Full lifecycle.
Production proven.

Senior Android Developer with 6+ years of hands-on experience building, deploying, and maintaining production-grade Android applications. Proficient in Kotlin and Java, I work across the full app lifecycle — from architecture design to Play Store release.

I've hardened live production apps against security breaches, shipped biometric fraud prevention features, and used internal projects as a deliberate space to explore emerging tools — including React Native, AI-assisted development with Claude Code, and Anthropic's Claude API. Based in Kochi, Kerala.
