I'm John. I’m a freelance software engineer and writer based in London, UK. I grew up near L.A. I make native iOS, Android and Web software for clients, ranging from radio and podcast tools to scientific data apps.
My programming experience stretches back to my youth, during which I was obsessed with Commodore Amiga computers and earned extra credit for writing a BASIC game about elves during trig class.
Lately I’ve done things like design and build an app for a conservation project in Madagascar, where scientists needed a new way to measure human activity in coral reefs. It's being used on the beach by octopus fishers. I also do stuff with Unix, Web servers and databases. As a journalist and book author, my work has been featured in the New York Times and on NPR.
I build, document and advise clients on how best to implement:
