At OKX, I overhauled the iOS and Android architecture for offline-first use, improving resilience during weak connectivity and increasing user engagement by 10%. I also owned delivery of advanced trading features and built automated test-generation pipelines.
At DoorDash, I drove $11M in savings by refactoring customer self-service modules and architecting a chatbot-first SDK. I led a six-engineer squad through the design and launch of a Sendbird-based SDK, and piloted feature-flagged releases with Product Managers and Data Scientists.
At Groupon, I refactored a legacy checkout into modular Kotlin MVI components and integrated multi-currency payment providers. At CSG Ascendon, I helped bring ExoPlayer into the core white-label SDK, adding adaptive MPEG-DASH streaming, Chromecast V3 support, and live TV playback.
At TCS, I built mobile prototypes, coordinated client and offshore delivery, and designed Android architecture training. My current engineering work includes Python/FastAPI tools for incident investigation, natural-language-driven app actions, and on-device mobile inference.
