I’m building a casual “Spin-to-Win” mobile game in Flutter and I’ve reached the point where a second pair of expert hands will speed everything up. The codebase is already set up in Flutter stable, relies on CustomPainter and AnimationController for the wheel, and is wired to Firebase for Auth and Firestore. The next milestones are polishing the wheel animation, tightening the overall game loop, and preparing the back-end calls for rewards, leaderboards, and future AdMob / in-app-purchase hooks. This is an equity-only collaboration—no invoices, no fixed salary, no “try-and-see.” I’m looking for someone who can treat this like a product we own together, not a gig that ends when the last ticket is closed. You should be comfortable delivering clean, testable architecture and squeezing the best possible frame rates out of Flutter. If you already know how to thread Firebase Cloud Functions into a real-time casual game, you’ll feel right at home. Deliverables for the first release • Refactor and optimise the current wheel animation so it feels smooth on mid-range Android devices • Implement secure reward logic with Firebase Auth + Firestore • Package the build for internal testing (Google Play internal track) Acceptance criteria • 60 fps or better on a Pixel 4-class device • No build-time or run-time warnings in Flutter stable • All Firebase calls succeed gracefully even on spotty connections What you gain Equity in the product from day one, the chance to co-own a real monetised app, and a seat at the table as we scale. If you need guaranteed cash or plan to “learn on the job,” this isn’t the right fit. If you thrive on building polished, animation-heavy Flutter apps and want skin in the game, let’s talk.
