...app built from the ground up and, just as important, I want to understand every step that goes into creating it. Your role will be two-fold: first, deliver a fully functional APK (plus clean, well-commented source code); second, walk me through your architecture, toolchain, and deployment process so I can replicate or extend the project later. Core expectations • Native Android build (Kotlin or Java with Android Studio). • Standard social features—user registration/login, profile editing, posts with images/video, likes/comments, and real-time notifications. • Secure back-end (Firebase, Supabase, or a lightweight REST API with SQL) and cloud storage for media. • Clear documentation: project setup, key code sections, and build/submit steps for Goo...

...platform is Android only, so please focus on the latest Android SDK while keeping compatibility back to at least Android 8. I already have wireframes that outline a familiar social feed: users create profiles, follow one another, post photos or short videos, like, comment, and receive push notifications. Your role is to refine the UI to Material Design standards, build the front-end in Kotlin or Java, and connect everything to a scalable cloud back-end—Firebase is my first thought, but I’m open to an alternative you can justify. Robust authentication, real-time data sync, and basic content moderation hooks are essential. Performance, security, and clean, well-commented code will guide acceptance. Deliverables: • Android Studio project with full source and comme...

I need an experienced full-stack developer who can look at my existing Java- and Python-based application, identify where machine learning will add the most value, and then build those features over the coming eight months. Your first task will be a short discovery sprint carried out through TeamViewer: we will walk through the codebase together, map the data flows, and agree on the key machine-learning opportunities. The priority use-case is classification, and it must surface across: • the user interface (smart suggestions and contextual prompts) • backend processing (automated decisions and scoring) • data analytics (actionable insights and dashboards) Once the roadmap is clear, you’ll pick up fortnightly stories in our tracker, write clean, test-...

I’m looking for an experienced Android developer to step in and refine an existing native app. The core build is stable, but it still lacks a reliable, well-structured push-notification system. Your task is to review the current Kotlin/Java codebase, integrate (or repair) FCM-powered notifications, and be sure they respect the app’s current UX flows—no rogue alerts, no missed messages. Once the notifications are live you’ll help me run a quick round of QA on a small device matrix, package a signed release APK, and supply the updated source in Git so I can keep the repository current.

I have an existing Java Spring web application that has been running for a few years and now needs a full refresh. The immediate priorities are: • Migrating everything to a brand-new server and hosting environment • Updating all Spring-related code and third-party dependencies to their latest stable releases • Implementing a handful of new features that have been on my backlog The current stack is Spring (Boot & MVC), Maven, MySQL and a small front-end in Thymeleaf with a sprinkle of jQuery.

I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface.
