Full-stack developer - Product-minded engineer

Ideas in.
Systems out.

I design and ship polished web products across the stack, from expressive interfaces and resilient APIs to data models, deployments and the tiny details that make software feel finished.

03 - About the craft

Make complexity
feel obvious.

My sweet spot is the seam between product and engineering: turning ambiguous requirements into systems people can understand, maintain and trust. I like small interfaces, strong primitives, boring infrastructure where it helps, and bold details where they matter.

const product = { idea: "worth shipping", ux: "clear", api: "durable", deploy: "repeatable" };
