I'm Diego — an AWS Solutions Architect and backend engineer with 6+ years turning enterprise requirements into systems that stay fast, secure, and affordable as they scale.
I architect cloud platforms and build the backend that runs on them — designing AWS infrastructure as code, then writing the Java and Python services that move the data through it.
My work has lived inside demanding environments — Banco Santander, BBVA, Santalucía — where systems have to scale under load, pass audit, and stay available without drama. I care about code quality, efficiency, and getting the architecture right the first time.
Designing cloud and backend architecture for enterprise clients — translating business requirements into scalable, well-architected systems on AWS.
Grew across a consultancy partnered with Banco Santander, BBVA and Santalucía — designing AWS infrastructure with Terraform, building Spring Boot and Python services, and running platforms on EKS and OpenShift.
Every component assumes its neighbour will fall over. Redundancy, graceful degradation, and tested recovery are the baseline — not the upgrade.
If it isn't in code, it doesn't exist. Infrastructure is versioned with Terraform, reviewed, and rebuildable from a clean account in an afternoon.
Automated tests, static analysis, and clean architecture keep systems honest — so they stay efficient and maintainable long after launch.
The best system is one your team can operate without me. Clear diagrams, runbooks, and golden paths outlast any single architect.
