A small studio, on purpose.
We keep the team small so the people who plan your product are the same people who build it. Fewer meetings, fewer hand-offs, better software.

Hi, I'm Petro.
I grew up in a village in Vojvodina, in the north of Serbia, and I still build software from here. I studied IT in Novi Sad, graduated in 2021, and have spent the five years since building mobile and web products across fintech, e-commerce, fitness and IoT.
I've led a React Native team for a German fintech app and a team of eight on a large e-commerce project, built a training and booking app for a Swiss fitness company, and worked with international teams at Vega IT and on IoT apps published to the App Store and Google Play. Along the way I mentored interns and junior developers and learned what makes projects go well: clear scope, honest estimates and shipping often.
I started TEOS IT to work that way with every client. Today I lead a small team with a dedicated UI/UX designer, and we also build our own apps — Kellion and Hortium — because shipping our own products keeps us sharp for yours.
