Selected work

LLM eval harnesses, AI agents and computer vision. Client names stay private, so each project has a codename.

  1. Blueprint Vision

    Construction tech, Computer vision

    Computer vision for construction takeoff. Models find HVAC symbols on drawings, and each human fix becomes new training data.
