Hi, I’m
Matt.

Currently building Claktor
Refactoring agents that make codebases smaller.

Previously, I built a trading solver
that routed $15B in user orders.

I like AI and programming languages.

I built and ran a CoW Protocol solver on Ethereum and Gnosis Chain, competing against a dozen teams, some backed by venture capital.

In 2025, I sold Barter access to the codebase and retained the IP.
