Principal Design & Brand Architect at GitHub. Creator of Bootstrap. Previously at Twitter. Huge nerd.

Mark Otto is a designer living and working in San Francisco. Originally from Wisconsin, he freelanced his way through high school and college before dropping out and moving to California to work at a design firm, ZURB, in 2007. There he designed and developed dozens of projects with clients large and small, including his favorite, a website for Britney Spears. In early 2010, he left to become a product designer at Twitter.

At Twitter, he worked on numerous projects including the Promoted Products campaign tools and badges, Twitter.com during #NewNewTwitter, the Twitter Help Center, and several internal tools. He also created the popular open source front-end toolkit Bootstrap with @fat. In late 2012, he left Twitter to join GitHub.

As a product designer at GitHub, he worked on tooling for GitHub Enterprise, helped redesign Issues, redesigned conversations, designed split diffs, shipped mobile web notifications, and iterated on GitHub.com’s design with ships like redesigned repositories, system fonts, dark header, and more.

From late 2015 to early 2017, he served as GitHub’s Director of Design, managing a newly unified team of nearly 30 designers, artists, and writers across Product and Marketing. In early 2017, the GitHub Design team split and he moved to Marketing full-time as Senior Director of Design. For two and a half years, he managed a team of roughly 25 web designers, engineers, and artists that maintain GitHub’s brand, marketing sites, and creative campaigns.

As of July 2019, he’s GitHub’s first Principal Designer, focusing on brand, marketing, workplace, and event keynotes.

About the site

This URL has been my online home for many years, manifesting at times as a blog or a portfolio until landing on this current single-column blog. Today it’s a bit of an outlet graveyard for my design-and development-related ramblings.

In case you were wondering, this site is:

  • Designed and coded on a Mac in California
  • Coded with Atom
  • Built on Jekyll, the open source static site generator
  • Hosted on GitHub Pages

You can find more about my macOS development setup in my config repo on GitHub. The design and code powering this site, however, is not available for re-use or purchase.
