How I work
- 01 Build reusable foundations
- The expensive parts of software — auth, billing, sync, deployment — should be paid for once and reused across products.
- 02 Keep the daily action simple
- Products people use every day must cost seconds. Depth belongs behind the main loop, never in it.
- 03 Design for local-first resilience
- Apps should work offline and anonymously by default. The network is an enhancement, not a dependency.
- 04 Treat product and engineering as one system
- Pricing, copy, schema, and architecture constrain each other. Designing them together is what independent building makes possible.
