About

A student who ships

I'm a high school student in Michigan, heading toward a career as a CPA. Accounting and development need the same habits: get the details right, keep things organized and make sure the numbers add up.

I also run NightOwl Voice, an AI phone receptionist for trade businesses, so I know what a small business needs its website to do.

I build custom code instead of drag-and-drop templates, so your site or game system does exactly what you need and nothing it doesn't.

I use AI tools to work faster. I test and fix everything myself before you see it, and I'll tell you straight away if a job isn't a good fit.
