What I'm looking for

I’m looking for a product-focused team where I can lead Flutter/Dart mobile delivery end-to-end, collaborate on React/Next.js frontend, and build maintainable architectures (Clean Architecture, BLoC) with reliable CI/CD and strong testing.

I’m a Mobile Application and Frontend developer with 5+ years in Flutter and hands-on experience in React and Next.js. I’ve built and shipped 11+ production apps, including a Top 20 Google Play sports platform, and I work confidently across full-stack development with NestJS and FastAPI.

I’m also an expert in BLoC and Clean Architecture, and I love owning the details that make apps reliable in production. Currently, I’m a key role developer at Salasto FZCO in Dubai, managing the full mobile product lifecycle—independently handling App Store and Google Play deployments, release cycles, and even certificate/provisioning maintenance while building interactive storytelling experiences for iOS/Android/Web.
