What I'm looking for

I’m looking to build and optimize high-scale Android products where performance, reliability, and maintainable architecture matter. I want to keep mentoring engineers, raise code quality, and use data-driven benchmarking to improve real user outcomes.

I’m a Senior Android Engineer with 6.5+ years building high-performance, large-scale mobile applications. I’ve delivered measurable impact—like reducing portfolio screen latency by ~80% and improving geo-fencing accuracy by 10× from 100m to 10m.

My work focuses on performance profiling, stability, and end-to-end product ownership. I’ve optimized WebView memory usage to improve stability on low-end devices, built a macrobenchmarking framework for data-driven releases, and improved app startup time and memory footprint through rendering and asset pipeline optimizations.

I also care deeply about engineering standards. I’ve led architecture refactoring (including mapper/transformer layers), mentored junior and mid-level engineers, and raised quality through regular knowledge-sharing—so teams ship faster with cleaner, more maintainable modules.
