Matthew Weaver is a project engineer with 11 years of hands-on experience in heavy civil construction, water infrastructure, and field engineering, currently at Allan Myers Inc. He progressed from excavation and residential construction to inspecting multimillion-dollar municipal water upgrades at the Philadelphia Water Department and helping win and execute a $22M Delcora wastewater project. Comfortable bridging office and field work, he produces takeoff estimates, manages submittals and RFIs via CMIC, writes subcontracts, and coordinates crews and suppliers to keep complex projects on schedule and compliant with PA steel and OSHA requirements. An entrepreneur as well—founder of Timberwolf Tree Service—he brings practical finance, risk management, and scheduling discipline learned running a small business through the pandemic. Unusually for a construction professional, he also contributes to formal mathematics tooling on GitHub, working on category-theory formalizations in the UniMath Coq library, demonstrating strong analytical and proof-driven thinking. Based in Philadelphia with a BS in Finance from Drexel, he combines technical project delivery with entrepreneurial grit and a knack for process automation.

Contributions summary:Matthew's contributions center around formalizing mathematical concepts within the UniMath library. Their work involves defining and proving theorems related to category theory, specifically focusing on concepts like slice categories, functors, and adjunctions. They are also working on the equivalence between different categorical constructions and contribute to establishing these mathematical foundations using Coq. The commits demonstrate a deep understanding of category theory and formal proof techniques.
