Data Scientist & LLM Engineer · building agentic AI, writing about the craft.

I am a data scientist and LLM engineer based in Tel Aviv. Most of my work is in agentic AI — designing multi-agent workflows, wrangling retrieval, and building the unglamorous plumbing that decides whether a clever system actually holds up in production.

This site is where I think in public: essays on intelligence, field notes from the build, and the occasional detour into the harder questions — privacy, meaning, and what we are really making when we make machines that reason.
