01. services

I take a problem and ship the smallest thing that solves it, solo or embedded in your team for a quarter or two.

what-are-we-building.mp4

On-screen text, in order:

  1. it starts as an idea.
  2. built all the way down.
  3. and it works.
  4. ai that fits your business.
  5. agents your team can trust.
  6. products, built end to end.
  7. fixed, not rewritten.

  • ·Workflows automated from request to booked job[3][6][7]
function aiInBuild()
  • ·Specs and rules any coding agent can pick up[2][3][8]
  • ·Multi-agent workflows with defined roles and review[3][4][7]
  • ·MCP servers that give agents live docs, errors and data[2][3][4]

04. about

Stefan Kovachev
→ portrait.jpg

❯I build bespoke web apps for ops-heavy businesses, the kind where spreadsheets stopped scaling six months ago.

Full-stack dev, obsessive about architecture: the domain model, the boundaries, and the boring infrastructure that keeps it up at 3am. I spec, design and review; agents handle the volume. Having built it all by hand is why I know when they're wrong.

Started at SAP Labs and Fraunhofer back when "ajax" was still a buzzword. Picked up a Diplom in digital media in Kaiserslautern and an MBA from Worcester somewhere along the way.

Three spoken languages, bg, en and de, plus fluent typescript.
