Notes on building minimal but powerful software: deterministic systems, performance as a feature, privacy by default. Few words, each one earning its place.

• 2026-05-10I built an MCP server for a knowledge graph. It doesn't call any LLM.Most MCP servers assume an LLM in the pipeline. This one is a deterministic memory layer: grounding, not retrieval.
• 2026-03-30I spent months trying to stop LLM hallucinations. So I wrote a graph engine in Rust.Why prompt engineering, RAG, and vector DBs weren't enough — and how Kremis became a deterministic verification layer instead of another generator.
