About

I'm a full-stack developer who started out keeping factory equipment running, not writing code — and that background still shapes how I build software: I care about things working reliably in production, not just in a demo.

Since 2021 I've shipped full-stack products end to end — APIs, front ends, deployments — and over the last year I've been upskilling into AI systems engineering, designing and shipping AI-powered features as part of an internal product suite at MSD.

I'm most useful on teams that need someone comfortable moving across the stack: happy writing a FastAPI service, a React interface, or the Terraform that deploys both.
