About
I'm Maxwell Howe. I teach math and make maps on the North Shore of Massachusetts.
This is the fun half. Small tools I actually use (sun times, address lists, seating charts), plus maps and games that didn't need a client. Everything is free, runs in your browser, and asks for nothing.
The hire-me half lives at maxwellhowegis.com. Case studies and the work I'd show an employer. If you're deciding whether to hire me, start there. If you just want a sun calculator, stay here.
The radars are daily notes on what's new in maps and developer tools.
