03How I work

Principles I build by

  1. 01

    Simple systems are easier to debug, extend, and hand off.

  2. 02

    Correct code matters more than clever code.

  3. 03

    Performance is a feature, not an afterthought.

  4. 04

    Constraints clarify decisions.

  5. 05

    Ship it, then iterate.
