Accountant · Auditor · Builder

I audit the books,
then I build the system.

Accountant and California sales & use tax auditor — CPA exams passed, completing the experience requirement for licensure. I spend my days testing whether transactions were recorded and taxed correctly — and my nights building the software that gets it right the first time.

For fun.

I sing, and I play guitar — sometimes both at the same time. The through-line with accounting is not as strange as it sounds: both are structured systems where the constraints are the interesting part.
