Thinking

A notebook, not a blog.

Notes and essays on building products. Nothing here is dressed up as finished thought.

  • Jun 2026AI as an Idea HunterAI is more useful to me as a way of finding and pressure-testing ideas than as a replacement for building them.
  • May 2026What mastery-learning software should actually doIf the software cannot tell whether a learner can do the work, it is not teaching. It is presenting.
  • Apr 2026What happens when software becomes cheap to create?The interesting question is not whether one person can ship a product. It is what becomes scarce once building is no longer the bottleneck.
  • Mar 2026Lessons from building GuessorA geography game looks like maps and photographs. Most of the work is identity, sharing, and making a round that a stranger can finish without you.
  • Feb 2026Building products as a software engineer in South AfricaThe internet is global. Payments, attention, infrastructure and the nearest collaborator are not. That gap is part of the work.
  • Jan 2026What AI changes about the one-person software companyA single person can now cover more of the surface area of a product. That does not remove taste, distribution, or the need to keep the thing alive.
