I’m Eduard Barrera, a Backend Software Engineer & Open Source Developer based in Colombia 🇨🇴.
I design and build reliable backend systems, developer tools, and AI-assisted engineering infrastructure.
If an idea or problem appears, chances are I’ll architect it, build it, test it, and ship it.
My main tech stack is TypeScript, Node.js, Python, PostgreSQL, and Docker. I focus strongly on REST APIs, multi-tenant architecture, automated testing, CI/CD, clean architecture, SOLID principles, and code quality.
I also work with real-time systems, developer tooling, static analysis, and AI/LLM integrations, with a strong interest in reliability, observability, and developer experience.
