02About

A studio of one, building practical software.

Run by Yannis Bertels — a developer focused on digital products, internal tooling and AI-driven experiments. Background in full-stack engineering with a strong focus on product, usability and clean execution.

Most projects start as practical problems. An internal team needs better tooling. A small business wants a polished web presence. An experiment wants to become a real product. The studio takes those briefs and ships them end-to-end.

The work spans web applications, internal interfaces, automation tools and AI-driven side projects. Different domains, same approach — build the thing that actually solves the problem, make it feel professional, ship it.

AApproach
  • 01
    Practical first

    Solve the real problem first. Polish, refinement and visual craft come after the thing actually works.

  • 02
    Clean execution

    Strong typography, restrained motion, focused interactions. Details compound — the small ones decide whether software feels professional.

  • 03
    Built end-to-end

    From data layer to UX, shipped as one piece. No hand-offs in the middle, no rough edges between parts.

  • 04
    Iterate small

    Ship the smallest valuable thing, then refine from real feedback. Speed of feedback is the single biggest predictor of quality.
