I work on experimentation at Vinted. The other hours go to the bike, and to models.
01 — Ride
Quiet roads, long loops.
Most of the thinking that sticks happens on the bike. No agenda, one number on the computer, and enough distance for a problem to get simpler.
The line on the left is that kind of route: a loop with a climb in the middle and an easy roll home.
02 — Work
Did it actually move?
At Vinted I work on experimentation. Which metrics we trust, how a test is read, and whether a change moved the thing we cared about.
03 — Models
A computer for the next hill.
I use AI the way I use a bike computer. It does not ride for me. It shows the split I would have missed, and shortens the distance between a question and an answer.
- AskTurn a fuzzy question into something that can be measured.
- CheckPressure-test an analysis before it becomes a decision.
- BuildPrototype the small tool that makes the next one faster.
