Background
I'm a software and cloud architect with over 20 years of experience designing scalable systems. Currently at Avallain, I lead the architecture of AI-powered educational products serving millions of learners worldwide.
My focus has evolved from hands-on development to strategic technical leadership: designing AWS cloud infrastructures, defining system architectures, and guiding teams through complex technical challenges.
I've collaborated with startups and enterprises across Europe and the US, spoken at conferences about development practices, and contributed to open source projects. I'm passionate about building systems that are not just functional, but maintainable, scalable, and cost-effective.
20+ years in software development, AWS cloud architecture, EdTech & SaaS products. Remote-first since 2008. English & Spanish.
Certifications
Continuous learning keeps my architecture decisions grounded in current cloud capabilities.
