Sreekuttan J S
Full Stack Mobile Developer
I build high-performance cross-platform mobile applications with Flutter, engineer robust backend systems with Golang, and create educational YouTube content for Kerala Entrance exams.
Professional Summary
Full Stack Mobile Developer with 2+ years of professional experience. I specialize in building scalable mobile applications using Feature-Driven MVC and MVVM architectures, and engineering microservices backends with Go (Golang).
I have hands-on experience bridging Flutter with native Android APIs (Kotlin, BLE) and building offline-first systems using SQL/SQLite. Beyond development, I run a YouTube channel creating educational content to help students prepare for Kerala Entrance exams (KEAM).
