About Me

I architect the invisible stuff — the infrastructure, systems, and automation layers that let products scale with confidence.

Over two decades, I've gone from hands-on coder to team mentor and platform architect. I've worked across startups and scale-ups, led teams through serverless transformations, and integrated LLMs into production systems — all while staying close to the code.

I'm currently looking for Principal Engineer or Staff-level roles where I can apply deep AWS and backend architecture skills to solve hard, meaningful problems.
