What I'm looking for

I seek roles where I can lead cross-platform Flutter development, optimize performance, implement scalable architecture, and contribute to CI/CD and DevOps to deliver high-impact products.

I am a Senior Flutter developer with 4+ years of experience building production-grade Android, iOS, Web, and Android TV applications from end-to-end. I specialize in Clean Architecture, performance optimization using Flutter DevTools, real-time systems, and AWS CI/CD pipelines, and I have delivered apps with 100,000+ downloads and 4.3+ Play Store ratings.

I focus on improving app stability, load time, and developer productivity through structured state management (GetX, BLoC, Provider), dependency injection (get_it, injectable), and robust DevOps practices (Docker, CodePipeline, CodeBuild). I enjoy solving cross-platform challenges and shipping reliable, high-traffic user experiences.
