About

I don't build websites. I build production systems.

Every project I take on is architected from scratch, engineered for real-world load, and deployed into environments where failure is not an option.

From enterprise SaaS platforms with AI pipelines to mission-critical election systems deployed at live events — I build things that work when it matters.
