Implemented Play Asset Delivery (PAD) to reduce Ixigo Trains app size by 2 MB, boosting Play Store ranking and improving install conversion. Optimised Docker-based CI/CD pipeline by preloading Android SDK and build tools, cutting build time by 50% and eliminating flaky builds. Integrated CrossSell in the Train Waiting List PNR flow, increasing cross-sell flight and bus bookings by 20% and directly growing revenue. Eliminated UI jank on high-traffic list screens by flattening view hierarchies, removing overdraw, and optimising LazyColumn item composition – lifting average frame rate to a steady 60fps. Reduced cold start time by ∼400ms by deferring non-critical initialisation and implementing a SplashScreen API-compliant launch flow. Collaborated with cross-functional teams to define, design, and ship new features end-to-end on a platform serving millions of users.

Solely designed and developed the Device Interaction Module for Samsung Health SDK, enabling real-time 100Hz sensor sync from Watch to Mobile via GMS with 99.83% efficiency. Achieved ≤150ms end-to-end latency by building a lightweight pipeline with queuing and flow-control mechanisms optimised for wearable-to-mobile streaming. Designed and built real-time sensor data visualisation components – rendering live heart rate, SpO2, and activity graphs using Canvas API with smooth 60fps updates and no frame drops under continuous 100Hz data throughput. Implemented microservices-based chunked Sync Layer at the Wearable Framework to prevent OOM issues during large data transfers. Delivered 40+ features and resolved 300+ issues across sync, UI rendering, and data integrity; collaborated on-site with Korea HQ engineers.
