01 / about
About
I like finding a real, annoying problem and just building the tool that fixes it. Working pool service routes gave me a field-ops app; volunteering at my church gave me a website to maintain; a 48-hour hackathon gave me a working prototype that won its category. I'll reach for whatever actually solves the problem.
