Description

Senior Android Engineer with 15+ years of experience building, modernizing, and scaling mobile products for global companies including Meta, American Express, Rakuten, Hopper, and Agoda.

I specialize in Kotlin, Jetpack Compose, mobile architecture, and performance optimization, with a strong focus on solving complex engineering problems in large, business-critical Android codebases.

Over the years, I have worked on:

• large-scale platform and API migrations across Facebook, Instagram, and Messenger;

• Android app consolidation and CI/CD automation at Rakuten;

• conversion-focused product improvements at Hopper and Agoda;

• performance, stability, and accessibility improvements on the Resy app at American Express.

I am particularly interested in Android projects involving architecture modernization, legacy refactoring, performance and reliability, or technically demanding product environments where strong engineering judgment matters.
