I'm the design lead on the Twitter's Abuse team. If the problem were as simple as "get rid of trolls," we'd be done already. I wish!
Instead, it's a cat and mouse game and the most complex design problem I've ever had the good fortune to work on. My team has been hard at work and there's no end in sight.
I was a design lead on Windows Phone, in charge of the team designing 1st party apps like Mail, Calendar, and Messaging. I also worked with partners like Office, Skype, and hundreds of third party developers.
I moved from Windows Phone to Office, where I led the design of new versions of Word, Excel, and Powerpoint for small screens. Getting the Office "ribbon" onto a four inch screen was a lot of fun and hard work!
I worked on dozens of different projects, the most complex being a redesign of mainframe software for Computer Associates. (I can't talk about most other projects because of how frog's NDA works)
That project taught me that I love complex problems. It was an order of magnitude more complex than any mobile app I'd worked on, and I loved it.
UX Launchpad teaches hands-on and fun design classes. For the first few years, we based them out of a space in Seattle, but since then we've moved to full-day seminars on site at companies.
The company also puts out a lot of design essays, including the popular Design Explosions. In issue #1 we compared Google Maps and Apple Maps.
I love public speaking and chatting and would love to hear from you. You can contact me at firstname.lastname@example.org.
