Cross-Platform Mobile App Development

@Microlent

Hello! I can take your concept from idea to polished, store-ready apps on both iOS and Android with native-quality performance and a clear roadmap for launch. What I’ll deliver • Technical roadmap and milestone plan (architecture, tech choice, CI/CD). • Regular device-ready builds you can test (weekly or biweekly). • Clean, documented source code in a private repo. • Full app store packaging + submission support (App Store & Play). • Post-launch support window for urgent fixes. Approach I’ll propose the best stack (Flutter / React Native / native) based on your priorities, implement auth, push notifications, IAPs where needed, and set up automated builds and tests so releases are repeatable and safe. Work is iterative with demos and fast feedback loops. If this fits, I’ll prepare a 1-page technical plan and estimated timeline so we can start immediately. Best regards, Jasmin.
