Lead Android Engineer at Code and Theory who cut clean build times by 40%.

India
Message

At Code and Theory, I defined end-to-end Android architecture for a high-traffic consumer app using Jetpack Compose and MVI, reducing UI bug rate by about 30%. I also designed a multi-module architecture that cut clean build times by 40%.

I built an in-house production-ready app template adopted org-wide and engineered a custom deep-link system that replaced Firebase Dynamic Links, reducing cold-start link resolution latency by 50%. I owned the release pipeline, maintaining a crash-free rate above 99.5% across production releases.

At Y Media Labs, I contributed across Android, React Native, and Roku apps, and co-designed shared component libraries and SDK-level architecture. My work also includes banking app security hardening, startup-time optimization, and integrating Gemini API and on-device ML capabilities into Android architecture.
