donatj/README.md

Hello!

I am a PHP, Go and TypeScript developer based in Minneapolis.

I work across the entire stack, but I’m happiest in the backend. Moving data, pushing bytes around, making things fast.

I ❤️ tiny reusable parts with single responsibilities and no side effects. I keep code simple, clear, and easy for anyone to read.

I’ve spent fifteen years in EdTech keeping old systems running and new ones from catching fire. Before that I built industrial and B2B tools where things had to work because people depended on them.

What I've been up to recently

I’ve been building picopass, a TinyGo experiment that turns a Raspberry Pi Pico 2 W into a physical TOTP keyboard. It pulls time over Wi‑Fi/NTP and presents itself over USB as serial and HID, with buttons for typing the current time, a stored password, or a fresh one-time code. I also used its documentation as the basis for a GitHub Markdown rendering report.

What I have been thinking about

I’ve been thinking about putting effort into better macOS support where it can make a real difference, rather than recreating strengths Linux already has. I’ve also been impressed by coding tools that can produce a useful first pass, and I’m curious about how they’ll reshape the everyday rhythm of writing software.
