What I'm looking for

I'm looking to build robust, user-friendly mobile applications, solving production challenges across native iOS and cross-platform stacks.

I've built and maintained consumer mobile apps at TechTreeIT Systems, including Tata Starbucks, Café Coffee Day, Geekay, Viya, and Chitale Bandhu.

I reduced payment failure incidents by building a Firestore-backed transaction tracker with automatic retries across CC Avenue, Juspay, and Razorpay. I've also maintained crash-free user sessions above 99%, strengthened security with iXGuard, SSL pinning, jailbreak detection, and Keychain storage, and automated releases through Bitrise.

I led the company's React Native adoption by architecting and shipping Chitale Bandhu, a production loyalty app, from scratch using TypeScript, Redux, Axios, React Navigation, and AsyncStorage.

Across native iOS and cross-platform development, I focus on robust, user-friendly applications that solve real production problems.
