The systems behind the résumé.

Four client systems I lead or led, written for engineers and hiring teams: what the business needed, what I built, the decisions behind it, and where my part ends.
Private repositories are described, never linked. Every number is counted from code, Terraform or git history; a client's business metrics stay with the client.Platform & AI Engineer · Technical Lead · Relocating to Tokyo · 2027

Platform, DevOps or AI-platform role? Let's talk.

I build and run production systems on AWS, and I deploy and operate models in them. I'm looking for a senior platform, DevOps or AI-platform role, and I'm relocating to Japan in 2027. A résumé and references are available on request.
