Check out my latest work

I've worked on a variety of AI/ML projects, from memory systems to workflow automation platforms. Here are a few of my favorites.

RAG Search Engine

End-to-end Retrieval-Augmented Generation system with hybrid retrieval (BM25 + dense embeddings), cross-encoder reranking, evaluation harness, and an agentic generation pipeline. Built to scale from semantic search to multi-modal document understanding.
