Senior mobile app developer scaling fintech and ecommerce with server-driven UI expertise.
IndiaWhat I'm looking for
I’m a senior mobile app developer with 10+ years building and scaling mobile applications, including 6+ years at Amazon India. I’ve owned ambiguous problems end-to-end—from design to launch—on teams like the FireTV & Device group, where I led performance optimization and helped drive reliable weekly release delivery with zero escalations.
At Amazon, I authored release cadence SOPs and internal wiki documentation to improve on-call efficiency, standardized settings UI across the FireTV platform, and led org-level service migration plus Lambda optimization as a team POC. I also lead engineering with hands-on delivery: I built server-driven UI for dynamic page rendering, developed offline support for low-connectivity regions, improved crash-free sessions (98.91% → 99.99%), enhanced security (SafetyNet Attestation and credential hiding), and mentored engineers to raise Android best practices.
