90% of solo building:

  • Debugging alone
  • Reading stack traces
  • Rewriting the same function
  • Staring at logs

10%:

  • Shipping

That 10% makes the rest worth it.

PM wrote the spec.
Designer questioned it.
Engineer built it.
QA tested it.
User broke it.

Same person.

All the hats. One head.
