About Me

Building things that scale & ship

I'm a Senior Java Engineer at Amadeus Labs with 6+ years designing distributed systems — microservices, event-driven architecture, CI/CD pipelines. Led Java monolith-to-cloud migrations, cut deployment times by 30%, and built REST APIs serving thousands of concurrent users.

More recently I've gone deep on AI integration — not just experimenting, but shipping. My end-to-end content automation pipeline powers 5 active YouTube channels: script generation via Claude API, image rendering via ComfyUI, voice, ffmpeg assembly, upload queue. Zero human intervention.

I care about clean architecture, 99% test coverage, and systems that don't page you at 2am. Open to remote roles in backend or AI-integrated product engineering.
