About

Days, I’m tech lead at Gone.com, and most of the job is AI: building with it, measuring it, and getting the whole company using it. Evenings, I run my own experiments, and this site is where they land: how I run Claude, what I’ve launched, and what resale taught me.

Resale came first. Years of it, in a business where margins are thin and mistakes show up in a box on your doorstep. Price it, list it, see if it sells, fix it. Gone is resale too, with trucks and AI pricing, so the day job uses both halves.

Now

Tech Lead at Gone.com

Gone picks up the stuff you don't need, for free, and resells it. I lead the engineering team and architected the core operations platform. Most of my impact is with AI, in three areas.

  • Using AI to build and ship fast

    10+ apps, built with AI, that track our items end to end and put the data in front of every team.

    • 10+ apps
    • Item tracking, end to end
    • Data for every team
  • An eval system

    A framework for running pipelines against golden test sets, scoring each combination of model, prompt and tool use on value and other predictions. Experiments run 100k+ times on startup cloud credits.

    • Model and prompt
    • Tool use
    • Golden test sets
    • Value predictions
  • AI across the company

    Getting every team using AI well, with the setup built for them and the teaching to go with it.

    • Workflows
    • Connectors
    • Custom MCPs
    • Teaching and demos

Before, and still: resale

Reuse Thrift. Years of sourcing, grading, listing and shipping secondhand stuff. It still runs, quietly.
