Back to original languageAbout Ángel David
I am a Full Stack Developer specializing in Backstage and Platform Engineering. Currently, I am technically leading an Internal Developer Platform (IDP) in production, used daily by the development teams of a large organization.
My specialty is building tools that reduce friction for other developers: custom plugins for Backstage, deployment automations, CI/CD integrations (GitHub Actions, CircleCI), and observability (Dynatrace, Datadog). I master the full stack: React/TypeScript on the frontend, Node.js and Java (Spring Boot) on the backend.
I have developed IDP portals and custom solutions for projects with INCIBE, Mapfre, and Prosegur. Speaker at the Cloud Native Latam Summit 2025 on Developer Portals.
If you need to build or improve an internal development platform, integrate Backstage, or automate processes to gain efficiency, I can help you. I work remotely with a clear goal: deliver something that simply works.
