What I'm looking for

I’m looking for a senior Flutter or mobile lead role where I can own architecture and ship secure, high-performance apps at scale. I’d like to work on products with real user impact, ideally in fintech or consumer tech, with a strong engineering culture that values clean code, testing and AI-assisted development. I also want to mentor developers and grow toward technical leadership.

At Zeta Tech, I architected a secure Flutter authentication flow for banking apps using SSO, token exchange, replay-attack prevention, and session isolation. I also integrated secure card SDKs while keeping raw PAN, CVV, and PIN out of the host DOM.

At Junglee Games, I reduced app startup and load times by about one second and built customizable private contests and milestone-based referral rewards. I also developed a Gemini AI proof of concept for team generation.

At Refyne India, I built a Flutter design system with the design team and managed iOS releases from QA testing through App Store deployment. I also helped establish a testing framework that expanded coverage to about 75%.

Earlier at GeekyAnts Pvt Ltd, I developed Flutter plugins using platform channels, including an Android SDK wrapper for DRM content playback. Across my work, I’ve focused on Flutter and Dart applications, app performance, testing, and secure mobile experiences.
