    Bio

    As a Code Wrangler at Automattic, Inc., I spend my days designing software. As a nomad, I own very few things and enjoy living simply. I love cooking, engineering, photography, and my faithful God, Jesus Christ.

    Interests

    I’m passionate about programming theory, engineering design, and teaching software design. If you want to meet up at a WordCamp we could spend hours into the night discussing any problem no matter how big or small and get out our laptops to explore some ideas together.

    WordPress Origin Story

    At the time I found WordPress I had been building primitive CMS systems out of Google Docs, Smarty, and FCKEditor – what a different world! Once I realized that I could have a fully-fledged website building system for free and which got better as time passed I was hooked and abandoned all of my custom website coding.
