3 years ago my wife and I began growing most of our own food. I’d never grown anything before and dedicated 2 years to obsessively learning about growing food. There’s a lot of information to memorize and to keep track of and from the beginning I knew a mobile app would make things much easier. I started learning how to code last year and released version 1 of our free mobile app that helps people grow food in November. We now have over 50,000 users and are adding 3,000 more every week. This talk explains how I learned to code, how I built it, and some of the motivations behind why. It’s also a call to action for developers to “code the change” they want to see in the world!
