About us

A small team of developers building products with care, craft, and a long-term mindset.

Serhii Vovchuk

Serhii Vovchuk

Above all values code that's still worth showing a year later. Loves diving into technical details and refining solutions until there's nothing left to remove.

Daniil Bondar

Daniil Bondar

Values projects where you can build a product people will actually use. Likes understanding both the technical side and the reason any of this is being built.

Pavlo Beniuk

Holds the whole picture in his head — from code to deadlines. Doesn't like chaos and works to keep it out.

What we build

Six areas. Pricing depends on scope — tell us about your project.

Small team, undivided attention

Your project is led by a founder, not a junior. You talk to the person who is actually writing the code.
