How I work
The principles behind every line of code I write.
Clean code
Code that humans can read, not just machines.
Keep learning
Always exploring new technologies and pushing past what I know.
Ship, then improve
Bias towards action. Build, iterate, improve.
User first
Every line of code serves a person on the other side.
Deep work
Focused sessions over scattered multitasking.
Simplicity
The best solution is often the simplest one.
