Hey guys, William here (guess what my nickname is). I've been working on and off with postale.io for a few years now, enjoying its technical challenges. Two of the things I like most about developing this service are the wide variety of things to do, and the freedom we have to pursue our goals. Being particularly interested in infrastructure and architecture, I focus most of my efforts there. I'm also happy to write a blog post from time to time. Hope you find one useful!
