I run Pulsometrs.lv, a sports tech shop in Rīga. I build side projects. I run marathons. I write honestly about what all of it looks like from the inside — the experiments that worked, the ones that didn't, and the tools I keep coming back to.
This is where I think out loud.
Latvia's specialist shop for Garmin, Polar, Therabody, Brooks, Maurten. Physical store in Rīga's Barons kvartāls, e-commerce across Latvia. Built from scratch, still run day to day.
