About us

Writing code with a mountain view

We're a two-person studio based in Poland's Bieszczady mountains. We combine senior engineering experience with original design, so we can own the whole project — from database architecture to pixel-perfect interfaces. We work with local businesses and with clients around the world.

Sebastian

12 years of commercial experience across startups, corporations, and freelance projects. He covers the whole stack: Go and Python on the backend, Vue and React on the frontend, and infrastructure on self-managed servers.

In 2025, he swapped Warsaw's office towers for the Bieszczady mountains. Today he lives in Ustrzyki Dolne and picks projects that matter — including for the local community.

After hours, he volunteers building websites for local businesses, newspapers, and the Ustrzycki Teatr Dramatyczny, helping Bieszczady culture stay visible online.

Ulyana

Frontend developer and UI designer from Belarus. After five years in Warsaw, she moved to the Bieszczady mountains to be closer to nature — and that's where, in 2024, her programming journey began.

She specializes in React and Vue (Next.js, Nuxt) with TypeScript. What sets her apart: she doesn't just implement other people's designs — she creates them, so what the client sees in the mockup reaches the browser without compromise.

She designed each of her 4 commercial projects from scratch around the client's vision — from online stores through gastronomy to agritourism. Her artistic background (drawing, poetry, music, ceramics) shows in the details and in how comfortable her interfaces are to use.

Why work with us

The whole project in one place

From database to deployment. No need to hire a designer, a developer, and a sysadmin separately.

Design and code, no broken telephone

Designer and developer sit at the same table (literally). Ideas don't get lost between mockup and code, and decisions take minutes, not weeks.

Experience you can see

12 years in the industry, startups and corporations behind us, and a portfolio spanning online stores, news portals, tourism platforms, and fintech.
