About.
I'm a systems-engineering graduate (INTEC, with a Master's in Web Engineering from UPM) who has spent 10+ years on the boundary between backend platforms and the frontends they serve — PHP, Laravel and WordPress on one side, React and TypeScript on the other. Most of that time has been spent operating, not just building: I currently maintain architecture, performance and security across a portfolio of 30+ production sites, including enterprise WordPress environments, custom ecommerce integrations and API-driven content platforms for healthcare, real estate and consumer brands. I'd rather build something reusable once than fix the same problem five times.
Currently deepening: TypeScript across the stack, Laravel-first architectures, and cloud infrastructure (Docker at scale).
