I need a macOS desktop application that automatically creates multiple-choice exams from an academic PDF using AI. I want to: • Upload PDFs and have the system analyze their content without requiring me to input a set of questions. • Choose, before each generation, how many questions the exam will have and how many answer choices each question will display. • When answering, have the application indicate whether I answered correctly or incorrectly and provide the justification, citing the exact article, section, or page of the syllabus that supports the correct answer. Main technical requirements: • Native execution on macOS (an installable .app or equivalent), without a mandatory connection to external servers once installed, except to call the AI ​​API of your cho...

I need a clean, well-structured Python module that connects directly to the Home Assistant API, handles authentication, and exposes simple functions for reading and updating entity states, firing events, and subscribing to real-time changes. Everything should be wrapped in reusable classes (ideally async-friendly) so I can drop the code into an existing project without major refactoring. While Home Assistant is the immediate focus, I also keep Google API and Gorq API integrations on the roadmap, so designing the code in a way that lets me add further REST endpoints later would be a bonus. Deliverables • Fully commented Python code (Python 3.10+) that authenticates and performs the core CRUD operations against the Home Assistant API. • A short demo script (CLI or Jupyter not...

I need a fully custom-built website that showcases a searchable, filterable product catalog. The site must be responsive, fast, and easy for me to update without relying on WordPress or Shopify. A lightweight tech stack such as HTML5, CSS3, JavaScript with a Node.js or PHP back end and a MySQL or PostgreSQL database would suit me well, but I’m happy to hear alternative suggestions that keep performance and security in mind. Core deliverables I’ll use to accept the project: • Front-end interface designed for mobile and desktop, including category navigation, product grids, detail pages, and an intuitive search/filter bar. • Back-end admin panel where I can add, edit, delete, and reorder products, upload images, and manage categories. • Basic SEO foundations (...

I am looking for a freelancer to help build a kid-focused online tutoring marketplace where parents can book vetted tutors for live online lessons. This platform will act as a marketplace, not a tutoring service itself. Tutors provide the lessons, and the platform handles discovery, booking, payments, safeguarding, and takes a percentage commission from each completed session. The platform commission will also cover operational costs such as tutor identity verification and safeguarding checks, meaning tutors are not charged any upfront verification fees. Project Overview The website will allow: Parents to find, book, and pay for tutors Tutors to create profiles, set availability, and accept bookings Admins to manage users, payments, commissions, verification status, and safeguarding The i...

I have a Siemens IOT2040 already running Node-RED and two flow-meters that expose their readings over Modbus registers. I need a clean flow that polls those two devices, keeps the register map exactly as it is, and republishes the same data over Modbus TCP so a Crimson-based PLC on the other side can read it without extra parsing or scaling. There is no data pre-processing involved: whatever the meters expose is what the Crimson PLC must see. All I’m after is a reliable bridge with tidy, documented Node-RED nodes and comments so future edits are easy. Deliverables and Remote Work: 1- I will provide access to Red node and computer connected to the IOT - work can be done remote connection or on your workstation then imported here, 2- There will be UIs on the Node Red to see wh...

I’m taking my neighbourhood kirana shop online and need a compact e-commerce site that feels effortless on any phone. The core of the job is a modern, clean design that loads fast and makes ordering as simple as walking to the counter. Day-to-day I’ll be adding or removing items as stock changes, so a straightforward dashboard where I can upload photos, prices and quantities from my phone is essential. At checkout we’ll start with a single payment method—Cash on Delivery—yet the flow should still look professional, send order confirmation emails and record each sale in the back-end. Customers may check out as guests or create an account to track past orders; please wire the site so both journeys work without friction. I’m flexible on the underlying sta...

Engagement Model Hourly Budget: $4/hour Long-term engagement Phase-based development Continuous work opportunit...

I’m building a mobile-only app that needs a real-time text chat backend dedicated to one-on-one conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic. I’m open to proven stacks such as Node.js with WebSocket/, Go with gRPC, or an equivalent solution that plays nicely with iOS and Android clients. End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable. Deliverables • Production-ready server code with clear setup instructions • Secure user authentication and encrypted message transport • Message persistence (Mo...

I need a reliable way to pull data from Facebook Marketplace seller pages at scale. The target platform is Facebook; other marketplaces such as eBay, Amazon or Etsy are irrelevant for this job. Here’s what I’m after: when I paste one or many seller profile URLs into your script or small desktop app, it should crawl every public listing on those pages and export the results to CSV or Google Sheets. I mainly care about item title, price, description, photos (image URLs are fine), posting date, item location and the seller’s profile link so I can trace each record back to its source. If you can collect additional fields that Facebook exposes, even better—just keep everything neatly labelled. No hard requirement on the stack: Python with BeautifulSoup / Selenium, ...

I’m overhauling the Reviews area of our site and need a developer who can fold an AI-generated synopsis into the page. The old “Reviews” block will be replaced with a new, responsive section titled “What People Are Saying”. Here’s the flow I’m after: when the page loads, the system pulls our most recent top-rated customer comments (source is already exposed via API). An AI model then distills those comments into a brief, natural-sounding summary—two or three sentences that feel authentically on-brand. That summary sits at the top of the section, followed by the existing individual reviews beneath it for full transparency. I’m flexible on the underlying model—OpenAI, Google Cloud, Watson, or another provider—so long as th...

Fix: Production Blank Screen on Replit-Deployed Full-Stack App (Dev Works Fine) Tech Stack: React 19, Vite 7, TailwindCSS 4, Node.js 20, Express 4, TypeScript, PostgreSQL (Neon), Drizzle ORM. Hosted on Replit (Autoscale deployment). The Problem: The app works perfectly in development mode, but after deploying to production on Replit, the browser shows a blank/white screen. No visible errors in the browser console (or provide any you do see). Build Process: Vite builds the frontend to dist/public, esbuild bundles the server to dist/index.js. Express serves the static files in production. The build command is npm run build && npm run db:push, and the production run command is node dist/index.js. What I Need: Diagnose why the production build renders a blank screen Fix the issue ...

I run a website and need a custom script that helps me climb Google’s rankings and drive a steady stream of organic visitors. The idea is simple: automate the heavy lifting of keyword discovery, on-page optimisation and rank tracking so I can focus on content and strategy rather than spreadsheets. Here is what I expect: • A well-documented script (Python, PHP, Node or another widely used language) that: – pulls fresh, high-intent keywords related to my niche – audits existing pages and flags optimisation opportunities for titles, meta descriptions, headings and internal links – tracks daily ranking shifts on Google and compiles easy-to-read reports or dashboards • Clear setup instructions plus a quick walkthrough on my server so everything r...

I need a full-cycle build of an e-commerce web application, starting with UX wireframes and ending with a live, cloud-hosted site. The look must be modern and clean, so every screen—from the product gallery to the checkout flow—should feel streamlined and intuitive on both desktop and mobile. Core scope • Design: High-fidelity mock-ups, responsive layouts, and a coherent brand style that aligns with “modern and clean.” • Development: Front-end (React, Vue, or similar), back-end (Node.js, Django, or comparable), relational database, and solid API architecture. • Key feature: a reliable shopping cart and checkout system with real-time price updates, multiple payment gateways, and confirmation emails. • QA & deployment: automated testin...

I’m looking for experienced engineers who can step into an active code-base built with React on the frontend and a Node.js backend, keep everything running smoothly, and leave the code healthier than you found it. Most of the work revolves around maintaining the existing platform—troubleshooting production issues, refactoring brittle components, tightening test coverage, and slipping in incremental feature requests without disrupting current users. What you’ll actually tackle day-to-day depends on your strength: • Frontend specialists will focus on React component updates, state management fixes, accessibility tweaks, and performance profiling. • Backend specialists will handle Node.js services, REST/GraphQL endpoints, database queries, and deployment script...

The frontend of the project is done. However, I am unable to integrate Supabase as it crashes when I do. I am not familiar with Supabase. This project has user management, with separate portals for Admin, Interpreter, Client, and Staff. It has various workflows (example: Registration-> User Management; Booking Request-> Job Creation -> Assignment Tracking -> Completion Report -> Invoicing -> Payment) and integrations between users (Admin <-> Interpreter, Admin <-> Staff). It is also important that email integration is seamless.

I’m launching a dedicated platform that will stream T20 matches in real time. Live video is the centrepiece, so the build has to handle an uninterrupted HD feed, adaptive bitrate (HLS or MPEG-DASH), and a responsive player that works on desktop and mobile alike. Beyond the core stream, I’d like the framework kept flexible: an area for quick score widgets, space for articles, and the option to turn on login-gated or premium access down the road. Think of it as a lightweight version of the big sports portals—purpose-built for T20 yet scalable for future series or even other formats. Key deliverables • Front-end interface (React, Vue, or plain HTML/CSS/JS—your call) with an embedded, responsive video player • Back-end service (Node, Laravel, or simi...

I have an existing React app and need the key pieces of the Polymarket privy-safe-builder example wired straight in. The focus is on two things: • User authentication & management – replicate the Privy-powered flow so users can sign up with email or social, link a wallet, and stay logged-in across sessions inside my project. • Smart-contract interaction – expose the same Safe-based contract calls shown in the repo (read, write, signature gathering, error handling), but adapted to the contracts my dApp already references. The codebase you’ll be grafting onto is a standard Vite + React setup with already in place. I’ll add you to the Git repository once we start; you can work in a feature branch and open a pull request when complete. Acceptance crite...

I’m ready to add PAN card verification to my e-commerce site. You’ll have direct access to the official API documentation, and the stack is already in place—Node.js on the backend and Vue.js on the frontend. Here’s what I need from you: • Backend (Node.js): create secure routes that call the PAN verification endpoint, handle token management, sanitise user input, and store the responses we need for order processing. • Frontend (Vue.js): build a clean form that collects the PAN, calls our new backend endpoint, and displays success or error states in real time. • Testing & hand-off: end-to-end tests confirming valid/invalid PAN handling, plus clear setup notes so my team can deploy with confidence. If you’ve integrated identity or payme...

I need help finishing a React-based e-commerce web application within the next seven days. The design files and API documentation are ready; what’s left is turning them into a polished, functional front-end. Here’s the scope you’ll tackle during the one-week sprint: • Wire the React components to the existing REST endpoints • Implement routing and state management so pages load quickly and data stays in sync • Hook up the product listing and search views, the cart flow, checkout, and basic user sign-in/out • Apply the provided styles and ensure the layout remains responsive down to mobile screens • Hand over clean, well-commented code in a Git repo as the final deliverable I’m looking for someone comfortable with React Router, Con...

I already have two live avatars that mirror real people as they speak to one another, yet the current pipeline adds several seconds of lag. I need your help driving total end-to-end latency (mouth movement, facial animation, and generated voice) down to a hard ceiling of one second while keeping everything completely self-hosted—no paid APIs or usage-based services. The finished solution must plug straight into my existing platform and remain free for the public to use. You will begin by profiling the present stack, spotting where frames or audio buffers pile up, then redesign the generation and streaming loop so that speech-to-text, text-to-speech, facial blend-shape synthesis, and video compositing all run in near real time. GPU acceleration, WebRTC, low-level ffmpeg calls, on-dev...

I need a secure, web-based panel that lets users liquidate their crypto directly into Indian Rupees. The flow is straightforward: a visitor creates an account with an email-and-password signup, checks the live conversion rate for the supported coins, chooses the amount to sell, confirms, and then reviews the completed order in a personal transaction log. Core requirements • Web interface only—no mobile client at this stage. • Real-time price feed so every quote shown and every sell order reflects the current market. • Simple user account area where people can update profile details and see an at-a-glance balance. • Transaction history page that records date, coin, INR value, status and reference ID. Technical notes You are free to pick the back-end...

I want to streamline two pillars of my customer journey through the WhatsApp Business API: end-to-end order management and secure phone verification. On the order side, the flow should cover placement, tracking, and final confirmation without requiring any manual intervention from my team. Customers need to see real-time updates, and the system must write each step back to my existing database (REST endpoint available; documentation ready). For phone verification, the system should automatically send a code, listen for the reply, validate it, and return the result to my app. No human action should be necessary once the user responds. Acceptance criteria • Single WhatsApp number handles both processes concurrently without collisions • Clear, commented code (Python, Node, or...

I need a secure, browser-based accounting platform designed for professional accountants. The system must live entirely in the cloud, offer multi-company ledger management, intuitive journal entry screens, adjustable reporting periods, drill-down financial statements, and a full audit trail. Seamless, automated integrations with major Banking systems are critical so statements can be pulled in real time and reconciled quickly. Likewise, the platform must connect to common Payroll systems, posting payroll journals without CSV uploads or manual data entry. I’m happy with any modern web stack—Laravel, Django, Node.js, or similar—so long as it is container-friendly and can be deployed on AWS, Azure, or Google Cloud.

I have a Base44 application that is already coded for the web and I want it running on my own virtual private server. The VPS is up, secured, and ready—what’s missing is the actual deployment. Here’s what I need to happen: clone or upload the current codebase to the server, install any required dependencies, configure environment variables, link up the database and storage locations I specify, and then expose the app at my domain with an SSL certificate in place. Once everything is live, a short, clear README or set of notes on the steps you took will help me maintain future updates without guesswork. Acceptance criteria • Application loads over HTTPS at the domain I provide. • All existing features work exactly as they do in my local build. • Deplo...

Senior Automation Engineer for Traffic Simulation & Referrer Spoofing I am looking for a specialized Automation/Growth Engineer to build a custom Traffic Orchestration System. The goal is to simulate "Viral" traffic spikes to specific URLs to test search engine ranking signals. The Technical Challenge: This is not a simple headless browser task. You must solve the problem of taking high-volume, raw human traffic (via Pop-Under/PPV APIs) and "cleaning" it through a Bridge/Redirect layer to spoof specific social referrers while maintaining session integrity. Core Deliverables: - Referrer Bridge: Build a script/server that receives raw hits and uses a "Double Meta Refresh" or similar logic to spoof (e.g., masking traffic to appear as if it's coming f...

I need a blazing-fast, fully responsive online store built with and Tailwind CSS. Use whichever backend stack—Node.js or Python—helps you move quickest, pairing it with either PostgreSQL or MongoDB for data storage.

I need a full-stack developer to build a website in Node.js that cleanly presents three core areas—business listings, a blog section, and a product showcase—supported by a secure admin panel. The admin area must let me create, update, and archive content for each of those modules using a straightforward email-and-password login flow. Visual direction is modern and minimalist: lots of white space, clear typography, subtle accents, and a layout that feels snappy on both desktop and mobile. I’m happy for you to pick the most suitable Node.js framework (Express, Nest, Next, etc.) and database, as long as the code is modular and easy for another developer to pick up later on. Key deliverables: • Responsive public site with the three content sections wired to dynam...

I need an OpenAlgo environment wired up to Kite Connect so the system can place and manage an options straddle on the Indian markets with an integrated delta hedge. The core logic is already outlined—I simply want it coded, tested, and ready to push live. Here’s the flow I have in mind: • At a scheduled entry time the program selects the ATM call and put, and th corresponding predefined hedges, fires simultaneous market orders through Kite, and records the positions. • The delta hedge continuously checks net delta and sends offsetting futures orders whenever the threshold I set is breached. • Stop-loss, profit-target, and end-of-day square-off rules must sit server-side to survive a local outage. • All trades, greeks, and P&L should stream to a li...

I’m looking for a developer who can build a social-networking web application from scratch. The core idea is to let users create profiles, post updates, follow friends, and exchange private messages—nothing overly complex at first, but the foundations should be solid enough to grow.
