Hi, I'm Juraj 👋

Full-stack + applied-AI engineer. I build AI automations, RAG systems, and custom internal tools for businesses that have outgrown spreadsheets — solo, end-to-end, in weeks not months.

What I ship

  • AI automation — n8n pipelines, Claude/OpenAI agents, scraping → enrichment → CRM
  • RAG systems — FAISS vector search, document Q&A, production-grade pipelines
  • Internal tools — dashboards, inventory, scheduling & payments (FastAPI + Nuxt)
  • MVPs — idea → deployed product, full stack, one pair of hands
