Hello!

Hi, I'm Pete Corey. I'm a software developer and owner of East5th, Inc. I've been working in the software industry since 2008. I've worked in various capacities for various different companies like Amazon, Tapestry Solutions, and Cigital. In 2015 I started working for myself, and these days I find myself largely writing back-end software solutions using Elixir and Node.js.

I enjoy writing about what I know. Everything on this page was written entirely by me without AI assistance. Here's a sampling of some of my recent posts:
