Nick Smit

Senior AI / Full-Stack Engineer — based in Geneva / Zurich, Switzerland.

Currently lead contributor at Delta Labs, the Zurich AI startup (UZH spin-off, €4.4M seed Mar 2026) building Elaiia — an AI customer-simulation platform powered by Recursive Language Models (RLM).

What I build

  • Production RAG / semantic search on Postgres + pgvector + DiskANN
  • RLM inference & multi-turn persona-generation services
  • Agentic AI / MCP (Model Context Protocol) framework — codified team-wide
  • OCR / document parsing pipelines for proprietary enterprise documents
  • The orchestration / evaluation / reliability layer that turns AI prototypes into production
