Full Stack Developer & AI Engineer

I build software that reaches production: from the interface to deployment, plus AI agents when they really help.

I can help with.

A website or product from scratch

I design it, build it and deploy it: from the interface to the database, on web and mobile.
Modernizing an old system

I refactor legacy code, document the APIs and renew the interface without stopping the business.
Automating with AI

Agents and automations with LangGraph and LLMs that work on their own and alert you if something fails.
Third-party integrations

Official APIs, authentication and validations, like the integration with the Spanish tax agency.

Tell me your case

A little about me.

I have always been curious about how things work, and computers were the first thing that hooked me. I started on my own and later made it formal with a Higher Vocational Degree in Cross-platform Application Development at U-tad and a Python bootcamp.

Since then I have worked in banking, in a tax product and in management software with more than 25 years of history. I like to understand the whole problem before touching code, and I am just as comfortable polishing an interface as setting up deployment.

With AI I do two different things: I use it to work better, and I build solutions that integrate it, like the agents and automations in my products. The first speeds me up; the second solves problems. Neither replaces knowing engineering.

MadRing Guide

A PWA to follow the Spanish F1 Grand Prix at the MADRING circuit in Madrid, with the week's schedule, transport, circuit zones and live timing. It draws the cars' positions in real time on a track generated from the telemetry itself, with no per-circuit illustration.
- A proxy with a 25 s cache, single-flight and staggered requests keeps within the OpenF1 rate limits however much traffic there is.
- The schedule is rendered on the server so search engines and AI assistants can read it without running JavaScript.
Product, design, frontend, backend, database, deployment and SEO.
August – September 2026. Launched at the GP on 11–13 September.

Stibios Agent Platform

A platform of autonomous AI agents, running 24/7, that generate content, analyze trends and qualify leads for several projects: Revista Victoria, MadRing and Blog Stibios. It orchestrates LangGraph graphs with Gemini 2.5, publishes to Sanity and Supabase and reports through Telegram with no human intervention.
- Eight agents are in production: news, dev briefing, blogs (Stibios, Victoria and Pádel), leads, trends and the MadRing scraper.
- They run on GitHub Actions, with cron and manual runs, with no server of my own.
Full stack developer and architect: complete design of the platform, all the agents and the infrastructure.
