uttam dutta

I’m a Senior Mobile Engineer with 4+ years of hands-on experience shipping real-time, AI-powered mobile features. My work focuses on performance optimization, reliability, and production-ready architecture.

At Housing.com, I built Houzy, an AI Conversational Property Assistant using Kotlin and Jetpack Compose with a real-time streaming chat over Server-Sent Events (OkHttp SSE). I also integrated screen-aware AI context and remote-config rollout with OpenAI, boosting platform leads by 6% in 2 months.

I designed a self-verification flow for 500,000+ brokers with an in-app camera, location tracking, on-device contrast/blur detection, and image compression. I’ve driven unit-test coverage across 7 modules—authoring 500+ tests with JUnit4 and MockK—and mentored 2 interns while partnering with PMs, design, backend, and QA.

Earlier, I improved React Native performance by integrating Shopify’s FlashList, increasing a high-usage screen’s performance by 40% and fixing scroll rendering issues. I also resolved cyclic dependency problems that forced full reloads, restoring proper hot reloading and cutting daily development time.
