About

Who I am

>cat ~/about.md

I write code that ships on time and doesn't wake me up at 3am. Full-stack means I'm accountable for all of it.

From schema migrations to the pixel that's exactly 1px off. I care about architecture as much as design.

Zero drama. Several NDAs. Sole dev on a product people actually pay for. One rule: ship something I'm proud of.
