Marcus Kazmierczak is a software engineer working in a Research and Development group at Automattic, the company behind WordPress.com. Marcus publishes his open source software at github.com/mkaz. He is a firm believer in open source and the hope of technology to empower and enrich our lives for the better.

Previously, I was the founding engineer at a start-up called Maya’s Mom. Our company was acquired by BabyCenter. I continued working for BabyCenter as VP of Engineering, leading the engineering team developing new features and services for millions of moms around the world.

I worked briefly at CNET as a consultant on the Haystack storage project, which was a massive storage solution for the Webshots photo sharing site. We basically built a closed Amazon S3 system a month or two prior to Amazon, they smartly did an open service.

I cut my technical chops at E-TRADE Financial for many years during the go-go dotcom days. I worked in the Architecture group on problems such as site scalability and performance. I also led the embracing of open source and converting the data center to Linux and open services such as Apache and Tomcat, which were radical ideas back then.

I live in the Bay Area with my wife and two daughters. I’m an avid photographer, check out my personal site at mkaz.com to see my photo blog and galleries of my work. Plus I write various articles about technique and camera hacking that I’ve done.

A few other spots you can find me is my Family Site which is basically cute pictures of my kids. At mkaz.blog I write random things like books I read and other non-tech things. I post art, sketches, and doodles on Instagram under @marcuskaz but I prefer posting where I can control my own content.
