I’m building a focused productivity tool for Android and need a seasoned full-stack developer who can own the entire journey—from polishing the native Android interface to standing up the backend that powers it. On the front end, you’ll design and code an intuitive, responsive UI that feels at home on modern Android versions. You are free to leverage Kotlin or Java as you prefer, provided the end result meets current Material guidelines and performs smoothly on a range of devices. Behind the scenes, I’ll rely on you to architect and implement the server side. That includes database design, secure API endpoints, user authentication, and any real-time features the app may require. I’m open to popular stacks such as Node.js with Express, Django, or even Firebase if it makes sense—just explain your rationale. Deliverables I need to see: • A fully functional Android APK (or AAB) ready for Play Store testing • Source code for both mobile and backend, cleanly organized and documented • A short setup guide so I can run the app and server locally • Brief hand-off call or video walkthrough once everything is stable If you’ve shipped Android productivity apps before and can point me to code samples or live links, that will help us cut straight to building. Let’s create something users will open every day to get more done.
