Education & Experience

Sports

The mat teaches what the classroom can't — how to handle failure, reset, and go again. That same loop is how I approach every pull request.

The Kaizen principles

Kaizen-driven

Every sprint, commit, and review is a 1% improvement opportunity.

Clean code first

Code is read far more than written. Clarity beats cleverness.

Ship & iterate

Working software over perfect. Feedback loops beat guessing.

Athlete's grit

Consistent practice beats raw talent. Show up and do the reps.
