Portrait of Evan Lewis

I'm a rising senior at the University of Maryland studying Computer Science with a machine learning concentration and a business minor. I'm interested in applied machine learning and financial markets, particularly in systems that produce answers you can trace back to a source. Most of what I build starts with something I wanted to understand better.

Knowledge graph view of HVAC distributor documents

GraphHVAC: AI Operating Manual

Python · Claude Agent Loop · Hybrid Retrieval · Evals

A retrieval system that answers operational questions for an HVAC parts distributor. It ingests manufacturer bulletins, regulatory filings, supplier emails, and SOPs into a knowledge base where every answer carries an inline citation to the document it came from. On a 30 question evaluation set, hybrid retrieval reaches 0.97 recall@5 and the agent loop reaches 0.98 citation recall.

3D globe visualization with the CoWoS packaging constraint highlighted across the AI supply chain

AI Supply Chain Globe

TypeScript · Three.js · React · Graph Modeling

An interactive 3D globe that maps the AI supply chain as a layered graph running from power grids and fabs through advanced packaging, data centers, and model labs. Bottlenecks such as CoWoS packaging capacity and grid equipment lead times are modeled directly, so selecting one highlights everything downstream that depends on it. Every node and edge traces to a public, dated source.
