What I'm looking for

I'm open to remote roles and to relocating with visa sponsorship.

At JUEGAENLINEA, I develop Laravel REST APIs and responsive SvelteKit interfaces for internal software, including business logic, role-based permissions, and PostgreSQL integration. I work on a 14-engineer team, and backend changes ship with PHPUnit tests.

I co-founded TrainUP, a multi-tenant gym-management SaaS that reached its first paying customer after a 30-day trial and now serves 100+ active members. I built its booking engine and payments module, and developed gym-ops-agent, a Claude Haiku pipeline that turns bank-transfer receipts into validated records.
