Beyond code
The why behind the work
I'm an engineer who likes building things I'd actually use. The clearest example: years of studying wine the hard way led me to build Sensium — so the discipline and curiosity outside of code feed directly back into it.
Outside the editor you'll find me on a ski slope, under a barbell, or nose-deep in a glass trying to call the grape blind — usually with my golden retriever not far behind.
Wine, seriously
WSET-trained and deep into blind tasting — the obsession that became Sensium.
Alpine skiing
A lifelong competitive skier; comfortable making fast decisions under pressure.
Powerlifting
Consistency, progressive overload, and showing up — the same loop as shipping software.
