Hi, I'm Grzegorz.
Android engineer, nine years in. Senior Software Engineer at Allegro by day; before that senior and then lead engineer at Centralny Ośrodek Informatyki, and Android work in Warsaw and Zurich before that.
The day job is the large end of the craft — big codebases, big teams, and a lot of people depending on the thing not breaking. sqTile Launcher is the other end: a local-first home screen I design, build, ship and support on my own, where every call is mine and I live with the consequences. Doing both keeps each one honest — the scale teaches discipline, the solo work keeps the standards from becoming somebody else's problem.
What I care about is the part people actually feel: how fast it opens, how little it asks for, how long it keeps working without maintenance. That shows up as a short permission list, no accounts, and no analytics SDK following you around. I ship in small updates and write down what changed.
sqTile is built under Grzegorz Radomski TECH. If you want to talk about a project, a bug, or just how something works — email is the fastest way to reach me.How it got here.
Two careers, in the order they happened.
-
Software engineer
Seven years across product teams in Warsaw and Zurich — and sqTile on my own time.
-
Data analyst
A year back with data before returning to engineering for good.
-
Software engineer
Six months that turned a side interest into the job.
-
Data analyst
Eight years of reading data for a living — where the habit of measuring things started.
