ABOUT

I’ve always wanted to know how things work — and then build a better version.

That curiosity is the whole story. It’s why I ended up in data engineering instead of deciding on it — pipelines are just systems for turning raw, formless things into something legible, and that’s the same instinct that sends me up a mountain with a camera or into a new codebase at 11pm.

I travel because unfamiliar places ask better questions than familiar ones. I photograph because a still frame forces you to actually look. And I write code because it’s the most honest feedback loop I know — it either works or it doesn’t.

Engineering and creativity aren’t two halves of my life I’m balancing. They’re the same process, pointed at different material.

VALUES

What I work by

01

Curiosity

The default state. If I'm not learning something, I'm bored.

02

Honesty

Case studies show what broke, not just what shipped.

03

Craft

Whether it's a pipeline or a photograph — sweat the details or don't bother.
