I design and ship Symfony systems .

Senior freelance Symfony developer and solution builder: I'd rather understand your business than stack up tickets. On agentic AI, I'm a step ahead, with MCP servers in production, internal agents, products.

What I build

What I do day to day, and what I can do for you.

01 symfony.service

Solid Symfony backend

I take over legacy the same way I start projects from scratch: APIs, domain model, performance. I design the architecture and ship, from the first commit to production.

  • Architecture & domain
  • API Platform / REST
  • Legacy takeover
  • Performance & debt

02 mcp.agents
differentiator

AI / agentic systems

MCP servers in production at Worldia & STS, internal agents that genuinely save teams time. I can wire the same thing into your tools.

  • MCP servers in prod
  • Agents & orchestration
  • Team tooling
  • Business integration

03 product.ship

End-to-end products

I shipped two products solo: Voyage Adventure (a "Zero Human Company", 6 agents, €49) and Colorazen. From scoping to sales, I know the whole chain.

  • Product scoping
  • MVP → iterations
  • Solution builder
  • Business vision
