I have a new concept—working title “Ubububinompn”—that I want to turn into a fully-featured mobile application. Because this is definitely a mobile app project, I need someone who can guide everything from the first sketch through store launch. Here’s what I expect: • Collaborate with me to refine the core idea, user journeys, and feature set. • Design a clean, intuitive UI that feels native on both iOS and Android (if you specialise in only one platform, let me know; I may still split the work). • Build the app with well-structured, maintainable code, using a modern stack you are comfortable defending—Swift, Kotlin, Flutter, React Native or similar. • Set up basic analytics, crash reporting, and a simple admin/back-end if the solution requires it (Firebase, AWS Amplify, or your proven alternative). • Provide a testable build, handle at least one round of feedback, then deliver final binaries, source code, and concise documentation so another developer can pick it up later. Acceptance criteria • A working app that launches without errors on current iOS and Android versions. • UI matches agreed wireframes and passes basic accessibility checks. • All core features work as demonstrated in a short screen-record video. • Code compiles cleanly from a fresh clone using the documented steps. Show me two or three live apps you have shipped, outline your preferred toolchain, and give a rough timeline you feel confident hitting. I’m ready to move quickly once I find the right fit.
