About me
Design that scales.
Vision that leads.
Well-designed software shares with art its most essential nature: expressing structure and beauty at the same time. Every architectural decision is an aesthetic choice as much as a technical one. Quality software does not aim to work. It aims to endure.
With over 17 years of experience, I have transitioned from fullstack development roles to technical architecture and design of large-scale systems, aligning technology with strategic business goals.
My focus lies on building sustainable software using DDD (Domain-Driven Design), hexagonal architecture, microservices, and asynchronous event models. Strong command of technologies like Laravel, Symfony, React, Node.js, and cloud systems.
I have designed key architectures for the Spanish Government — FACe and FORMA — and critical SaaS platforms in the sports sector (AvaiBook Sports) and real-time IoT (Libelium).
Currently working as a software development consultant, Freelance Software Architect, and Fractional CTO in Zaragoza, I advise companies globally on platform design, deep technical audits, and legacy system refactoring.
