Founder & Software Engineer
Years building software, shipping products, and starting businesses.
I've led architecture and development of e-commerce platforms, in-store digital experiences, and cloud infrastructure for companies like MediaMarkt across Spain, Portugal, and Europe — from full platform migrations on Shopify Plus to custom CDN solutions with 95% cost reduction.
Now I'm focused on building and shipping my own products, leveraging AI agents and modern infrastructure to move fast.
Self-taught. Always building.
Currently building AI-first developer tools — making APIs agent-readable and CI pipelines self-healing.
SWAGENT — API documentation for the agent era. Takes your OpenAPI spec and generates token-optimized
llms.txt for AI agents, full markdown for developers, and semantic HTML for browsers. 65 KB → 16 KB, same information. Open source, on npm.
Stitch — Open-source AI agent that autonomously detects, diagnoses, and fixes CI pipeline failures. Platform-agnostic. Orchestrator-agnostic.
Banners All Over — Shopify app for smart banner management with scheduling, targeting, and analytics. Built on Shopify Plus experience from years of enterprise e-commerce.
Most of my career was spent at MediaMarkt (9+ years), where I was technical owner and lead across their most critical digital projects in Iberia:
- MediaMarkt Canarias E-Commerce — Full ownership of the Shopify Plus operation. Built an ecosystem of 6 custom embedded apps powering checkout, logistics, invoicing, refunds, fraud prevention, and operations.
- MediaMarkt Portugal — Led the full architecture and migration to Shopify. +50% sales in month one, 2900% maintenance cost reduction.
- MediaMarkt Tech Hub Barcelona — Global technology solutions for 15 countries. Omnichannel innovation, in-store digital touchpoints, daily collaboration with teams across Europe.
Before that, I ran Twenty Four Colors (now x24labs), an independent studio where I delivered 50+ projects end-to-end for businesses across Spain. And co-founded GrowLandia, a digital media platform that grew to 400K+ social followers and 2.5M+ monthly page views across all Spanish-speaking countries.
