Work Experience

Senior Software Engineer — Android Development (B2B Technical Lead) at JioSaavn

June 1, 2021 - August 31, 2024

Led refactor of a unified SDK architecture to scale the B2B infotainment ecosystem from 3 to 8 hardware models by replacing fragmented per-device variants with a single unified APK driven by a runtime hardware profile mapping service. Optimized build pipelines by modularizing Gradle flavors, cutting 35%–40% redundant code and reducing onboarding time for new hardware models by 50% (6–8 days to 3–4 days). Streamlined cross-border QA by replacing orientation-specific builds with native resource qualifiers (layout/layout-land), reducing overall binary size by 5%.

Backend Engineer & Android Developer at Syphyn Innovations Pvt. Ltd.

December 1, 2019 - January 31, 2020

Built a full-stack real-time financial bidding platform with a Kotlin Android client backed by distributed MongoDB services. Implemented gRPC unidirectional streaming to sync sub-second in-app bidding state, achieving 0.14-second transaction path latency via optimized stream pipelining, localized state machines, and reactive Realm DB bindings. Owned Android transactional state lifecycle for bid dispatch, multi-state confirmations, and fallbacks modeled after POS-terminal communication paradigms. Developed automated integration flows using BloomRPC and JUnit verification prior to deployment on the Google Play Store.
