A backend developer for systems with complex business rules.

I’m equally at home writing new .NET services and reading a decades-old system that still runs the business — the kind of code most people would rather not touch.

That combination is the point. Most of the risk in modernizing a system isn’t the new code; it’s quietly dropping a rule the old one enforced. Holding both sides is how you move a system forward without first misreading what it was built to do.

I help teams understand, maintain, and modernize that kind of system without losing the business logic it was built to enforce — whether that means writing new code, extending what exists, or planning a path from one to the other.

Based in Spain. Available for independent consulting, contract work, and senior .NET backend opportunities — in Spain, across Europe, the US, and Latin America.
