About devjaime
Backend engineering, applied AI and a career built in production.
I’m Jaime Hernández, also known as devjaime. I work across software engineering, backend systems and applied AI. I care about production-grade systems: APIs, microservices, data pipelines, AI agents, RAG and tools that help real teams operate better.
My focus
Applied AI that connects with real data, processes and teams: tool-using agents, evaluable RAG, traceable automations and maintainable backends.
