Hi, I'm Ernesto Crespo 👋

AI & Backend Engineer · Tech Lead — building AI agents, resilient backends, and data platforms from Venezuela 🇻🇪

Electrical Engineer with 20+ years in tech and Python since 2002. Currently leading the backend architecture of a health-insurance platform (NestJS, FastAPI, MongoDB, AWS) with real-time payment integrations across Venezuelan banks. Free Software advocate since the Debian Venezuela days ❄️ Arctic Code Vault Contributor.

🔭 What I'm working on

  • 🤖 Prismal — an open-source, security-first multi-agent orchestration framework built on LangGraph: central supervisor + 26 specialist agents, 9 reasoning patterns, 9 RAG engines, provider-agnostic via LiteLLM, native MCP support (v3.0 — evolution of the now-deprecated LightAgent)
  • 🌎 vigia-eew — a real-time earthquake early-warning agent (EMSC WebSocket + USGS FDSN + Raspberry Shake), supporting humanitarian response in Venezuela
  • 🧠 LangGraph agent architectures — documenting and teaching 16 agentic design patterns
  • ⚡ Local LLM inference on AMD — ROCm, llama.cpp, and NPU (XDNA 2) benchmarking on Linux
