Full stack developer based in Spain (CET), working remotely and looking for a remote-first team.
I have two years of professional experience building and maintaining web applications in production. My day-to-day stack is TypeScript, JavaScript, Node, PHP and MySQL, and I own the full cycle: analysis, development, deployment and the technical SEO and performance work that comes after shipping.
What I am proudest of is Nibbly (playnibbly.com), a real-time 3D game that runs in the browser on desktop and mobile. I built it alone and it is live with paying users: 58,000 lines of TypeScript with the compiler in strict mode, an own Node backend with twenty-five endpoints (sessions, email verification, password recovery, payment webhooks, rate limiting, scheduled backups), 192 automated test suites, and continuous deployment on every push.
I also lead the backend of EHWO (ehwo.org), a two-person platform for online psychology consultations. I designed and built its REST API with token authentication and role-based permissions, and integrated Zoom video consultations plus two payment providers.
At Estudio Web Doce I build custom websites and WordPress themes and plugins, and I own the technical SEO of every project: Core Web Vitals, structured data, indexability and content architecture.
I use AI-assisted development daily and it is the direction I want my career to take: integrating language models into real products, not just using them as an editor autocomplete.
Languages: Spanish and Valencian native, English C1 (uncertified).
