Antonio Oliva Cárceles

AI Engineer · agents, retrieval and the infrastructure that keeps them honest

LinkedIn Email

I build generative AI systems that hold up in production. Backend engineer by training (Java/Spring), now working in Python/FastAPI on LLM orchestration, retrieval and evaluation.

🧩 What I work on

  • Agentic systems — multi-agent flows with LangGraph, LangChain and Google ADK; tools, memory and policies exposed over MCP and A2A.
  • Retrieval that survives review — chunking, pgvector/FAISS, re-ranking and continuous evaluation with RAGAS. Answers that cite their source, or admit they can't decide.
  • APIs and pipelines — FastAPI services with auth, rate limiting, tests and CI/CD; event-driven flows on Kafka.
  • Shipping and watching — Docker and Kubernetes on GCP/Vertex AI and AWS, traced with LangSmith and OpenTelemetry.
