I’m planning to release a new Android-based game and need a developer who can take it from concept to a polished APK on Google Play. The project is purely mobile—no web or iOS components—so your focus will be on Android Studio, Java / Kotlin or a preferred game engine such as Unity or Godot. Here’s what I have in mind: • Core gameplay loop, menus, and simple in-app sound effects • Clean, responsive UI that scales well across common screen sizes • Integration of basic ads or rewarded video (AdMob or similar) • Documentation plus full source code so future updates are straightforward Once the first playable build is ready, I’ll test it on a range of devices and send feedback; we’ll iterate until the final version is sta...

...identification document. The app will interact with a server and has the following high-level functionality: • The user takes a photo. • The app sends the photo to the server which checks the photo, the app communicates the results of the photo check to the user. The user can decide if he wants to take another photo or if he wants to continue. • In case the user continues, the “Final Processing” starts. The final processing step removes the background from the image and verifies purchase data. The app has a free and a premium option. For the premium option, the user can buy in the app credits (in app purchase). If the user has premium credits, he will receive a full resolution photo. Otherwise, he can get the photo for free at a lower resolu...

...already in production; performance slow-downs on the older Mirth instances are the issues I meet most often. All access is through AnyDesk screen-share sessions—no direct log-ins or code exports—so you should be comfortable working live while we talk through each ticket. Your background must cover both the classic Mirth interface and the newer BridgeLink tool-set, with enough HL7, JavaScript, Java and SQL knowledge to trace bottlenecks, tweak transformers, and keep message queues flowing smoothly. Typical tasks you’ll handle: • Diagnose and resolve performance issues on legacy Mirth channels • Update or patch existing channels/destinations across both platforms • Build an occasional new channel when a facility is onboarded • Docum...

I’m ready to move from concept to code for a full-featured appointment booking application built entirely with Flutter. The app will serve three distinct roles—Admin, Service Provider, and Customer—each with tailored dashboards and permissions. Core functionality I need: • Seamless calendar integration so providers can set availability and customers can see real-time slots • Secure payment processing at checkout (Stripe or a comparable gateway) • Push and email notifications for new bookings, changes, and reminders I’ll share a detailed reference app and brand guidelines once we agree to collaborate, and I’m happy to refine the scope together before sprint planning. Your deliverable will be a production-ready Flutter projec...
1. Project Overview(Backend Microservices System (SPRING FRAMEWORK ONLY)) We are developing a large-scale, enterprise-level digital commerce platform on a Java-based microservices architecture (Spring Ecosystem). The development phase is "LARGELY COMPLETED". We are not looking for a builder to start from scratch, but rather a "finisher"—a skilled Backend Engineer to take ownership of the existing codebase. The primary goal is to validate current integrations, stabilize the logic, and ensure the system is production-ready through rigorous testing. WE WILL PROVIDE TESTING HELP FROM OUR SIDE TOO. 2. Current Project Status & Scope The following microservices have been developed. Your role is to ensure these services communicate seamlessly, handle edge cas...
...platform is ready for future PCI DSS and SOC 2 audits. Payments & Wallets The app should be architected to plug into popular mobile wallets and local payment rails (think Apple Pay, Google Pay, and regional wallets) through clear adapter classes. A sandbox integration that demonstrates at least one live mobile wallet transaction will form part of acceptance testing. Tech Stack Native Swift/Kotlin or a robust cross-platform framework like Flutter or React Native is acceptable; I’m open to your professional recommendation as long as performance, security, and code maintainability are fully addressed. A containerised backend (Node.js, Java Spring, or similar) running behind an API gateway with JWT or OAuth 2.0 is preferred. Deliverables (MVP) 1. Unive...
...familiarity with Express (or a comparable framework), query builders/ORMs, and SQL optimisation is essential. Scope of this first phase is intentionally narrow—two key modules only: 1. Secure user authentication (email / password, bcrypt hashing, JWT sessions) 2. Payment workflow wired to either Stripe or Razorpay—single-charge flow with webhooks for confirmation and refunds The REST API should expose clean endpoints the front-end team can consume for sign-up/login, patient profiles, appointment booking, and payment intent creation. Please containerise the app with Docker, include migration scripts for the database, and document everything through Swagger or an equivalent Postman collection. Deliverables (all required for acceptance): • Well-st...

You’ll dig into the current workflow, pinpoint what’s slowing Facebook down, then implement and document the fixes. Whether the answer is smarter caching, lighter API calls, refined Graph API queries, or background processing, I’m open, so long as end-to-end update time drops noticeably and remains stable under load. Deliverables I’d like to see: • Baseline performance report • Optimised code or configuration with clear change log • Final benchmark showing the improvement, plus a short hand-off guide for future tweaks If you’ve alread...
