Projects
Side projects and experiments. Some live on their own subdomains.
- Cognition Playground ↗An overview of Devin, Cognition's AI software engineer, and how it compares to the other AI coding tools.
- Case Interview Trainer ↗Consulting cases with structure, brainstorm, math and synthesis questions, and a model answer for each.
- Mental Math Trainer ↗Timed drills for the arithmetic that comes up in meetings, with the shortcut for every answer.
- Venture Returns Calculator ↗Sliders for fund size, ownership, and failure rate. Shows how much of a fund's return comes from its single best company.
- Cursor Playground ↗A field guide to using Cursor day to day, with a comparison to Claude Code, Codex, Devin, and Droid.
Patents
Three granted US patents from my time at Nuro, all on the problem of handing something to a customer when there is no driver to do it.
- US 12,194,169 ↗Methods and apparatus for sanitizing an autonomous vehicle — A compartment that sanitises itself between orders, so a vehicle that carried groceries for one customer can carry a meal for the next without anyone cleaning it in between.
- US 11,951,941 ↗Methods and apparatus for enabling contactless command of a vehicle — Proving who you are to a driverless vehicle once it reaches the kerb, so the right compartment opens for the right person without anyone touching a handle.
- US 11,907,887 ↗Methods and apparatus for unattended deliveries — Completing the delivery when nobody is home: the vehicle arrives, and the compartment releases what it is carrying rather than waiting for a person to meet it.
