{ 8+ yrs · full-stack · legacy → modern }

I build and modernize business-critical .NET systems — from mission-critical desktop apps used daily by emergency services, to my own multi-tenant SaaS running in production. Clean Architecture, tested, deployed.

Own SaaS · Founder in production

Reservaki reservaki.es

A multi-tenant appointment-booking platform for small service businesses in Spain — hairdressers, barbers, beauty and massage centers. I own it end to end: architecture, code, deployment, and its first paying customer. Tenant isolation via EF Core global query filters; CQRS with MediatR; Clean Architecture enforced by automated architecture tests.

Salty Summer Mallorca saltysummermallorca.com

A commissioned website built and delivered for a client — designed, developed and shipped to production on a real brief and deadline. A compact example of turning someone else's idea into a working, public-facing site they were happy to pay for.
