What I'm looking for

I seek senior platform roles where I can own offline-first mobile systems, drive architecture decisions, mentor teams, and deliver scalable, high-performance Android platforms.

I am a Senior Android Platform Engineer with 8+ years building production-grade Android platforms used by 250K+ MAU, focused on offline-first distributed systems, large-scale data synchronization, and performance-critical architectures.

I’ve driven measurable improvements—30–40% performance gains, 99.8% crash-free sessions, P99 latency <300ms—through protocol-level decisions (REST vs WebSockets vs gRPC), concurrency optimization, and modular platform ownership. I author RFCs, lead design reviews, and mentor engineers.

My background spans FinTech, Enterprise, and Messaging domains where I own end-to-end platform reliability, observability, CI/CD, and AI-powered mobile features that increase engagement and reliability.
