I will first provide a test because I must see you can do the job. Plenty of work to follow I need help wiring a single, well-structured JSON file into our application so it can drive all configuration settings that currently live in several scattered places. The goal is to read that file at startup, expose the values to both our internal modules and a pair of third-party REST APIs, and then allow future updates without a full redeploy. Here’s what I’m looking for you to deliver: • Schema design or validation logic that guarantees the JSON stays consistent. • A lightweight loader (preferably in Node.js or Python—happy to discuss) that parses the file once, caches it, and hands the data off to the rest of the app. • Hooks or endpoint wrappers so t...

I’m setting up a subscription service that analyses home-collected urine and fecal samples and then pays participants for the data we extract. The heart of the product is an AI engine dedicated to kidney-function health diagnostics; everything else—from the postage-paid kit to the laboratory partner—already has a clear roadmap. What I need now is a freelancer who can transform raw lab read-outs into accurate, automated insights. You’ll architect and train the models, build the API that the lab will hit with each batch of results, and generate a secure, client-friendly report that flags kidney-related anomalies and actionable next steps. Python, R, or comparable data-science stacks are all fine as long as the finished solution ships in a container and deploys clea...

I need a clean, well-structured Node.js backend that exposes a REST API protected by JSON Web Tokens. The project should ship with everything required for full-cycle user management: sign-up, secure login, password reset flows, and an optional two-factor authentication step for extra security. Role-based access control is essential; the system has to recognise three distinct roles—Admin, User and Guest—and gate endpoints accordingly. Please wire this into the middleware so that adding new protected routes later is straightforward. Preferred stack is Express (or Nest if you feel it adds value) with modern JavaScript or TypeScript, bcrypt for hashing, nodemailer (or a comparable service) for reset emails, and a simple in-memory or SQLite store is fine for initial testing; I...

I need a clean Firebase project configured from scratch to power my web app. The core requirement is a Firestore database structured for user-centric data: authentication details, user profiles, and detailed activity logs. I already have the front-end in progress; what’s missing is a secure, scalable backend that I can plug straight in. The job covers: • Spinning up the Firebase project and enabling Email/Password (plus any other built-in methods you recommend) in Firebase Authentication. • Designing Firestore collections and sub-collections to hold the three data sets mentioned above, with indexes where they will matter for query speed. • Writing robust security rules that protect each document based on the currently signed-in user. • Supplying a concise...

I need a compact Node.js backend that sits between a chat widget and OpenAI’s latest Chat + Vision models. The flow is straightforward: a visitor drags-and-drops an image (or types a question) into the widget; the server sends the request to OpenAI; it then returns both the conversational reply and a structured product summary pulled from the image. From each image I must capture: • any text or barcodes present • key dimensions that appear on labels or packaging • colour and design cues worth noting • a link or filename for the stored photo itself Every chat turn—user prompt, image reference, OpenAI reply, the extracted fields, plus a session identifier—has to be pushed automatically into a Google Sheet through a service-account credential....

I’m building a straightforward online store for physical products and need someone who can put together the full stack with React on the front-end and Node.js (Express) on the back-end. Shoppers should be able to browse the catalogue, add items to a cart, and complete checkout without creating an account—guest checkout only. A key piece is the customer reviews feature. After a purchase, buyers must be able to leave a rating and comment that displays on the product page. Beyond that, keep the flow lean: no social logins, no complex payment gateway work at this stage, just the essential cart-to-order process with dummy or cash-on-delivery logic so we can wire in a real processor later. I’d like clean, modern UI components (Material-UI or Bootstrap are fine), a simple RE...

I’m building “Teman Curhat,” a safe space where anyone can reach out for confidential mental-health support. The core of the platform is an anonymous, one-on-one chat that pairs a user with a qualified counselor while keeping both identities hidden.

I need a developer who can design, build, and container-deploy a new API that will live in a hybrid landscape—part of it running in the cloud, the rest on-prem. The codebase will revolve around Node.js, Go, and TypeScript, packaged for Kubernetes so that services can be moved or scaled between the two environments without friction. Core capabilities the API must ship with: • User authentication (JWT or OAuth2, your call as long as it is secure and test-covered) • Data processing that can handle both real-time and batch workloads • External integrations, mainly REST and a handful of webhook-driven services The workflow I have in mind is straightforward: containerize the service, write Helm (or similar) charts for deployment, set up CI/CD that pushes to both cluste...

I have a Node.js backend that currently lives only in a ZIP archive. I want it living, breathing, and auto-deploying from GitHub to AWS Elastic Beanstalk every time I push. Here’s what I need you to handle from start to finish: • Spin up a fresh private GitHub repository, commit the existing source, and preserve its commit history with an initial “import” tag. • Craft a GitHub Actions workflow that installs Node dependencies, runs my existing unit tests, builds the artefact, and then deploys to Elastic Beanstalk. – Use OIDC-based GitHub → AWS authentication so no long-lived keys are stored. – Secrets such as the Beanstalk application name, environment name, and any env vars should sit in GitHub Secrets. • Configure the Beanstal...

I’m looking for a seasoned full-stack developer who can take a project from concept through deployment. The exact scope is still flexible—I may need to build something new, improve an existing codebase, or resolve a backlog of bugs—so I’m keen to hear what approach you’d recommend once you understand the requirements in detail. On the front end I’m open-minded: React, Angular, Vue, or another modern framework you’re comfortable with. For the back end, choose whichever stack you can move fastest in while keeping the code clean, testable, and scalable. Here’s how we’ll work: 1. We’ll start with a short discovery call where you’ll help me clarify goals, select the best architecture, and outline a sprint plan. 2. You&r...

My app is already deployed and the REST of the codebase runs fine on my Linux VPS. The missing piece is MongoDB: I still need the server configured from scratch and the existing dump imported so the application can finally read and write data locally on this machine. Here’s what I still need done: • Install and harden the latest stable MongoDB release on the VPS (Ubuntu/CentOS—whatever commands match the box). • Create the required admin and application users, set up authentication, and open only the necessary ports in the firewall. • Import the provided MongoDB dump so all collections and indexes come across intact. • Wire the connection string into my environment file, then restart the app and confirm that the API routes hit the database without e...

I’m building an online business directory from the ground up and need a developer who knows the Node.js ecosystem inside-out. The goal is a fast, scalable platform where companies can be added, searched, and browsed with ease.
