About

Staff-level Android engineer with 9 years building production Android — from e-commerce, logistics, fintech and health apps to my current role as the sole Android owner of a medical-device platform. I tend to live at the boundary most Android engineers never touch: where the app meets the firmware. I replaced a device's native OS UI with a custom kiosk application handling BLE/UART communication, remote telemetry and real-time logging — and when there was no physical hardware to test against, I built a high-fidelity device simulator that ran investor demos and a formative study with zero application issues. I've also shaped decisions above the app layer — identifying a RAM constraint that drove a hardware spec change before production, and standing up the OTA and UART-diagnostic tooling the team now depends on. Core stack: Kotlin · Jetpack Compose · Clean Architecture · MVVM · Multi-Module · Coroutines · Hilt · BLE/UART · MQTT · Firebase Increasingly focused on on-device ML / LLM inference on Android — the natural intersection of my embedded background and where mobile is heading. If you're building something hard at the Android/hardware edge, or an Android product that needs an owner rather than a contributor, that's the work I do best.

Staff Android Engineer at Vivance, May 2021 - Present · 5 yrs 4 mos, Bengaluru, Sole Android owner of a medical-device platform, responsible for the full Android codebase end to end. • Architected a multi-module Android framework enabling parallel development across the team and improving release maintainability. • Replaced the device's native OS UI with a custom kiosk application, owning the full stack from UI down to the device-communication layer. • Designed the BLE/UART communication layer between Android and embedded firmware for real-time control, command handling and logging. • Built a high-fidelity device simulator with no physical hardware — used in investor demos (ASN Los Angeles) and a formative study that ran with zero application issues. • Created an Android-based UART diagnostic toolkit that replaced PC-based testing, cutting hardware validation from days to hours and becoming the standard QA workflow. • Built an OTA release system on Firebase for automated QA delivery to dedicated devices, adopted across the full team. • Influenced hardware specification — identified a RAM constraint that drove a 1GB→2GB upgrade in early design, preventing post-production rework. • Stabilized the core app to near-zero crash rate within 2 months of joining; later secured external penetration-testing approval via obfuscation and build-hardening. • Recognized as the primary Android technical authority; awarded Best Employee twice. Stack: Kotlin, Jetpack Compose, Clean Architecture, MVVM, Multi-Module, Coroutines, Hilt, BLE, UART, MQTT, Firebase.
