rjalexa/README.md
  • 👋 Hi, I’m @rjalexa — a medical doctor turned AI engineer & software architect, with a background in service design and medical research.
  • 🤖 I build LLM-powered systems end to end: multi-agent applications, RAG, and precision-first entity linking — shipping to real users at cultural institutions (a museum concierge, a newspaper's semantic pipeline).
  • 🕸️ I work with large-scale knowledge graphs — tens of millions of RDF triples on Jena Fuseki / QLever, SPARQL, Wikidata — paired with vector search (Weaviate).
  • 🛠️ Fullstack & systems engineer: FastAPI/Python backends, Vite/React & Astro frontends, durable workflows with Temporal, plus local + hosted LLM routing (Ollama, LiteLLM, OpenRouter).
  • 🔧 I run my own production infra: multi-server Docker, Caddy, Tailscale, layered security (CrowdSec/fail2ban/nftables) and real backups (Borg/restic).
  • 🌱 I design complex AI-driven ETL pipelines, do NLP/NER on Italian-language corpora, and automate the boring stuff.
  • 📫 my email is bob and can be reached at my ralexander.it domain. I live on Central European time. Keep safe!
