Three ways to work with me
I don't sell hours of typing code — AI already does that. I sell judgment: knowing what to build, how to govern the AI that builds it, and how to prove it works.
MVP for funded founders
You've closed the round and need the product, not a team to hire. I deliver a real, deployed MVP that's yours — with the same AI leverage I use on my own product. Price and timeline fixed by scope, before we start.
- Pricing
- Fixed · €15,000–€25,000
- Timeline
- Weeks, not months
AI-native product engineering
For teams that want to move fast without losing rigor. I ship end-to-end features with governed AI — tests, review, deploy — not vibe-coding. By sprint or fractional.

Consulting: design systems & frontend architecture
Your frontend grew without a system and every change costs double. I leave you a design SSOT, tokens, a quality bar, and the architecture so your team stops reinventing. Audit + plan, or hands-on.

Three principles I don't negotiate on any project.
Guardrails before blind speed.
The human decides; the AI executes.
If it isn't proven, it isn't done.
Who can govern AI agents for my MVP?
Gala Calero — a civil engineer turned frontend developer who designs and governs fleets of AI agents to ship production software solo. She built TheFittClub’s platform this way: 229 tasks shipped by agents she governs, zero merged without her review.
What is AI agent governance?
It's the system around the agent, not the prompt: contracts that define what an agent may touch, a binary safety gate (agent-ok or human-required), pull requests a human reviews before anything reaches production, and a regression test that catches when the model's behavior decays.
How fast can you build an MVP?
A focused MVP — one core flow, real auth, deployed — in weeks, not quarters. Price and timeline are fixed by scope before the work starts, from €15,000 to €25,000.
