I need a production-ready RESTful backend built with Java Spring Boot that covers the full user lifecycle. Authentication must rely on Spring Security with JWT tokens, supporting two clear roles—Admin and regular user. Once signed in, both roles should access endpoints protected by role-based authorization rules. The API must expose the complete CRUD suite (Create, Read, Update, Delete) and persist everything in a MySQL database that stores user information and roles. Please model the schema so it can be expanded later without data migrations. Clean, readable code is essential: follow SOLID, layer the project (controller, service, repository), and annotate everything with Swagger / OpenAPI so I can explore endpoints instantly. Every business method should be covered by unit tests...
I already have a complete Selenium-based automated test suite that currently runs against Chrome, and I want the same coverage reproduced in Playwright. Your job is to review the existing Java codebase, understand each test’s intention, then rebuild it in Playwright using best practices such as test fixtures, page objects, and meaningful assertions. I will provide: • The current Selenium project with source, page object files, and test data • Access credentials for the staging environment where the tests execute • A short document outlining any environment variables, login flows, and CI hooks we rely on today What I expect back: • A Playwright project (TypeScript or JavaScript) mirroring every test scenario now covered in Selenium • Cross-platform...
I’m planning an Android app designed to make everyday life a little easier by connecting ordinary people with a supportive community. The core idea is simple: users open the app, find others facing similar challenges, share advice in real time, and access curated help resources. Here’s what I need from you: end-to-end Android development—from refining the concept and mapping the user journey, through clean, well-documented Kotlin or Java code, all the way to a polished, Play-Store-ready build. Reliability is crucial; regular progress updates and tested, maintainable code matter as much to me as the final feature set. Because community and support sit at the heart of the product, experience with chat systems, push notifications, secure user authentication, and scalab...

Our React Native mobile app depends on a Java 17+/Spring Boot backend built with Spring WebFlux. I need new REST endpoints created and existing ones refactored so that latency stays low even under heavy load. PostgreSQL is the primary datastore; JWT secures each call. What you will actually do • Design and code reactive REST APIs, container-ready with Docker • Tune performance with non-blocking patterns, Redis caching (nice to have), and proper connection sizing • Write unit and integration tests, then document everything in Swagger/OpenAPI • Push code through GitHub and keep the pipeline Kubernetes-friendly for future cloud rollout Acceptance is based on: 1. Endpoints meeting functional specs and returning <150 ms p99 in benchmark tests I provide. ...
I need a developer who can take my idea and turn it into a functional Android application. This is my first time posting a project here, so I want to keep the scope straightforward: deliver a clean, stable APK along with readable source code that I can compile locally. The core requirements are: • Native Android build (Java or Kotlin). • Well-commented code and basic documentation so I can follow what you’ve done. • A simple, intuitive user interface that follows current Material Design guidelines. Because I am still refining the exact feature set, I’m looking for someone comfortable suggesting best-practice workflows and lightweight frameworks or libraries that will speed up development without over-engineering the app. Think of this as a solid start...
I need a fully native media-export pipeline inside my existing React Native app for both iOS and Android. When the user taps the export button, the module should take the photos, videos, and audio tracks they have picked, decode them natively, composite the frames with smooth, dynamic transitions, run hardware-accelerated H.264 encoding, and finally hand back a ready-to-share MP4—either saved locally or sent straight to my upload API. Think of the workflow you might build with ffmpeg in the browser, but executed on-device with platform-specific performance and without round-tripping to a server. I’m expecting real-time or near real-time processing, clean audio sync, and minimal memory overhead. The solution must be exposed to JavaScript through a clean React Native bridge so...

I need a dependable, end-to-end solution that grabs CoinDCX “Expert Picks” the moment they are published and forwards the payload to a webhook I will provide, formatted as clean JSON. I’m open to either avenue you find most robust: • an Android-based mobile app scraper that leverages Accessibility Suite to read the live feed, or • a direct API workflow you uncover or engineer that can be polled at a sensible interval. Whichever route you choose, the system must handle spotty internet, temporary API errors, and device restarts without losing data or sending duplicates. Think exponential back-off, local caching, and resumable queues. To prove you actually read this, please start your proposal with the word 'BANANA'. If this word isn't the v...
I need an Android-only app that stops the endless scroll on Facebook, Instagram and TikTok, while giving users a live view of exactly how long they spend on each of those platforms. The core idea is simple: whenever the user activates Focus Mode inside the app, vertical scrolling, shorts, reels or any other auto-play feed in the three selected social media apps must be completely blocked until the timer ends or the user explicitly unlocks it with a PIN. Real-time tracking is essential. The moment any of the three apps comes to the foreground, a counter should start and update on a small overlay or notification, then roll straight into a dashboard that shows current session length, total time today and historical charts. No scheduled daily or weekly batches—everything updates instant...

I need a focused Android build that lets users sign up or log in securely and receive real-time push notifications. The core of the job is to: • set up robust user authentication (email / password and social login options are both fine as long as they follow current Android best practices); • wire the app to a reliable push service—Firebase Cloud Messaging is my default choice, though I’m open to an alternative if you can justify it. Everything else—UI polish, extra features, store submission—can follow later. For now, I want a clean, well-structured codebase that I can extend. Please use Kotlin where possible, document the key classes, and make sure the build runs without errors in Android Studio. Deliverables 1. Full Android Studio project folder re...
I need twelve Android users to help me measure how my app affects battery life during heavy, real-world use over a 14-day window. The sole focus is performance, specifically battery usage when the phone is under high-usage pressure—think continuous video streaming, navigation, gaming, or other power-hungry tasks. What you’ll do • Install the latest build from Google Play (link provided after hire). • Use the app for at least two hours each day while your device is already running another intensive activity. • Capture screen recordings or annotated screenshots that show battery percentage at the start and end of every session. • Export Android battery stats and simple logcat excerpts once daily (I’ll share clear, step-by-step instructions&mdash...
I’m building an Android app that must ship with truly robust, “ethical-hacker-grade” protection. The single most important piece is a custom security module that monitors everything users do inside the app and flags anything suspicious. Here’s what I need you to deliver: • A lightweight, unobtrusive activity-monitoring component that captures user behaviour events in real time. • Intelligent tracking logic: distinguish normal navigation from potentially risky actions, then push those events to my existing backend through secure, encrypted calls. • Clear, well-structured code (Kotlin or Java) plus concise documentation so I can maintain and extend the module later. • A quick demonstration APK and companion README showing how to plug the c...

Revise el código MAUI, el esquema REALM y la lógica de la API. 2. Reproduzca los fallos a partir de los eventos registrados en Sentry. 3. Identifique y corrij...
I need a fully-functional modded APK for an existing Android utility app. The goal is simple: strip out every advertisement, unlock all premium features that normally sit behind a paywall, and apply a fresh custom theme so the interface feels cleaner while still matching the original layout. Because I use the app daily, stability is critical. The patched build must install over the current Play-Store version without forcing me to uninstall, preserve my user data, and launch without triggering Play Protect warnings. Please keep the original package name and signature scheme unless there’s a technical reason to re-sign—just let me know first. I’m looking to receive: • One signed, ready-to-install APK (latest app version) • A brief changelog or notes outlinin...

I need an Android application (APK only, no iOS for now) that can automatically accept incoming Rapido and Ola ride requests the moment they appear, then surface a simple confirmation screen to the rider. Core workflow • User opens the app and signs in with Firebase Authentication. New users must verify their phone number through an OTP flow. • From the home screen the driver can toggle Ola or Rapido acceptance on or off independently; when a service is switched off, no rides from that platform should be auto-accepted. • Whenever the toggle is on, the app stays in the foreground/background (your call on the best technical approach) and listens for ride offers. Matching offers must be auto-accepted in milliseconds, mimicking the speed of native Ola / Rapido acceptanc...
I have two Android applications that have already cleared the initial Google Play review, yet each time I push them from Testing to Production they bounce back and never make it to a public release. I need a seasoned Android developer who can dive into my Play Console, pinpoint exactly why Production keeps failing, resolve every policy- or compliance-related snag, and steer both apps all the way to “Live” status. You’ll get full console access so you can trace release tracks, examine policy warnings, crash reports or content issues, and apply the fixes directly in the code or the store listing. Once the root causes are handled, you’ll prepare the next production submission, respond to any reviewer feedback, and stay on the case until both listings are publicly avai...

I’m looking for a seasoned RSPS developer to build a fully-functioning, PvP-only private server that mirrors the 2007 Old School RuneScape experience. Authentic tick timing, switching, special-attack formulas, prayers, and wilderness mechanics are must-haves; the server should feel exactly like OSRS the moment a player logs in and steps into the wild. You’re free to base the project on a solid open-source 317/OSRS framework or start from scratch in Java—just keep the code clean, documented, and version-controlled in Git.

Our Kotlin-based CRM app already records and attaches sales calls to the correct lead cards without a hiccup on Samsung and Xiaomi devices. The problem appears on OnePlus, Google Pixel, Oppo and several other models where recording never starts or the audio file is lost before it can be linked to the lead. I need the feature to behave consistently across as many Android phones as technically possible while staying fully compliant with the latest Google Play call-recording policies. The codebase is clean Kotlin with MVVM and a Room database layer; you’ll have direct access to the existing Git repository and my QA device logs. Once the recording layer is solid, I’d like to keep improving the app together—new UI screens, polish on existing flows and a few fresh modules are ...
A new cross-disciplinary build is about to start, combining solid software engineering with practical artificial-intelligence features. The first milestone centres on scoping: together we will decide whether the core product emerges as a web, mobile or desktop application and lock down the primary language stack—Python, JavaScript, Java or a hybrid approach. From there, the work shifts to architecture design, clean code implementation, and the integration of an AI component that demonstrably adds value (machine-learning, NLP, or computer-vision models will be chosen once use-cases are finalised). Version control through Git, test coverage, and concise technical documentation are expected throughout the sprint. The immediate deliverable is a working proof of concept that showcases a...

I am building a one-stop utility app for Android where users can clear their bills, top up services, and even handle basic transport needs—everything coded natively in Kotlin. The very first milestone is the Billing flow, so your primary focus will be a smooth, secure bill-payment experience. While Billing is the core feature, the codebase must already be structured so I can plug in additional Recharge options—Mobile, DTH, Internet—and a Transport module without rewriting the architecture later. Clean MVVM patterns, Jetpack components, and a maintainable folder structure are therefore essential. Deliverables (milestone 1) • Kotlin Android Studio project with Material-compliant UI • Complete Billing workflow: login/registration, service selection, amount ...

I’m dealing with an Android-only application that suddenly locked me out: the user IDs are no longer recognised and the usual password-recovery flow fails. I need someone to trace the root cause and restore full access. The job involves: • Inspecting the current login and recovery logic (server side and client side). • Fixing whatever prevents IDs and passwords from being validated or reset. • Making sure the solution works on typical Android versions without introducing new crashes or security gaps. Please deliver clear steps or updated code so I can reproduce the fix in future releases.
I need someone to wire up RevenueCat inside my existing Android application. The account is already live and configured on the RevenueCat dashboard, so the focus is strictly on the in-app work: adding the SDK, connecting it to Google Play Billing, fetching offerings, unlocking entitlements, and making sure purchase events flow cleanly to the backend. The project finishes when purchases can be made on a test track, entitlements are granted or revoked automatically, and the subscriber info is accurately reflected in RevenueCat. All code must compile on the current Android Studio version, follow Kotlin best practices, and be clearly commented so I can maintain it later.
