What I'm looking for

I'm looking for remote or independent-contract mobile work where I can own offline-first architecture, data synchronisation, delivery, and store releases across Flutter, React Native, Android, and iOS.

I've built and released offline-first mobile products for Devxhub, including Tanto, a Brazilian corporate reimbursement platform, and Farenow, a US multi-service super app. I own architecture, implementation, CI/CD, store releases, and post-launch maintenance end to end.

At Prabartan Information Technology, I led an offline-capable, multi-language EdTech platform serving 100,000+ students across five countries and sustaining a 4.7-star rating at 100,000+ daily active users. I built Firebase and SQLite synchronisation layers that kept lessons and progress available without connectivity.

I publish open-source Flutter packages for CRDT sync, accessibility, on-device voice commands, and UI tooling. Across Flutter, React Native, Android, and iOS, I focus on dependable data sync, native integration, and mobile apps that remain useful when networks fail.
