My name is Krystian Safjan and I'm a AI/ML Implementation Manager at Ernst&Young. I love programming and things related to computers and networks.
✍️ Sometimes I write on my blog - see last articles:
- The Real Cost of Model Migration - What Swapping LLMs Actually Requires
- The illusion of control in AI-assisted engineering
- Version Your Vectors - Index Versioning as the Missing Layer in RAG Observability and Compliance
- Publishing a Python CLI Tool to Homebrew
