Engineer — AI systems

I build the core from scratch: Rust ingestion, GLSL, retrieval.

I don’t import a brain — I build one.

BUILDER

§01 — What I build

I build the memory and retrieval that agents actually run on.

The retrieval stack is built from scratch — semantic chunking, multilingual-CLIP embeddings, agentic RAG with rerank and multi-hop. No LangChain, no LlamaIndex.

§02 — Stack

End-to-end — embeddings to infra.
