About Me

Senior mobile engineer who ships apps people love — powered by clean code and AI.

12+ years of building Android and Flutter apps used by millions — from Google Play Editor's Choice winners to YC-backed startup products. I care deeply about clean architecture, intuitive UX, and shipping code that scales.

These days I pair my mobile expertise with AI-powered tools like Claude Code to move faster without cutting corners — architecture, code reviews, testing, all of it. Currently the sole Android engineer at Hammr Inc. (YC W23), building construction tech from scratch.

AI-Powered Development

Leveraging AI tools like Claude Code to accelerate development — from architecture design and code generation to testing and code reviews.
