I already have a fully functional HTML/JavaScript baccarat predictor; the logic is proven and stable. What I need now is a production-ready package that runs smoothly everywhere. My top priority is seeing the Android and iOS versions live, and I also want a polished web app released in parallel. I’m open to whatever approach you believe will deliver the best performance—native Kotlin/Swift, Flutter, React Native, or another cross-platform framework—so long as the end result feels fast, looks modern, and never crashes. You’ll begin by reviewing my existing codebase, extracting the prediction module and UI assets, then adapting them to the chosen stack. A clean, minimal interface is a must, and I’m happy to collaborate on final styling details. Once the builds are stable, deployment all the way to Google Play and the App Store is in scope. Deliverables • Responsive web app hosted on my domain • Production-ready Android APK/AAB • Production-ready iOS build ready for TestFlight & App Store Acceptance criteria • All three builds reproduce current functionality with no regressions • Cold-start time under two seconds on typical mid-range devices • Consistent, modern UI with smooth touch interactions • Zero crashes during a continuous 30-minute usage test When you respond, please include examples of similar conversions or multi-platform apps you’ve shipped, your recommended tech stack, an estimated timeline, and a cost breakdown. I look forward to collaborating with a developer who can turn this proven predictor into a sleek, cross-device experience.
