Projects I've worked on

A selection of my recent work across products, client websites, and volunteer projects.

Product interface

Shards

Built the interface for a platform that turns documents into an explorable knowledge graph. Users can find relationships, such as people linked to the same company, review sources and ask questions about the graph through a RAG-powered assistant. Contributed Python backend code for document APIs, graph data and chat/indexing services, worked on PostgreSQL migrations and designed the logo in Illustrator.
