By day I build web apps — backend and frontend. On the side I freelance and build just about anything, desktop apps included, then write about the craft. This is the front door to it all.

Software, written down.
I'm Joshtri — a web developer working across backend and frontend, and a writer. I like building things that are simple on the outside and honest on the inside, then writing about what I learned along the way.
My day job is web development, but freelance I'll build just about anything — desktop apps included. The rest lives across open source repositories and a blog where I think out loud about architecture and craft. This page is just the front door — the detailed work sits on the portfolio.

One roof, three doors.
Everything I build and write, indexed in one place. Each door leads off this page to where the real work lives.
Let's build something worth keeping.
