In 2013, I joined the design team at Twitter. I was fortunate to work on a lot of varying projects, some rather large, some rather small. Twitter is a very data concious business, so a lot of my work was done behind A/B tests and not everything made it to the public, but quite a bit did.
I was fortunate to be part of the design team that created the redesign of Twitter in 2013. Moving direct messages from behind the profile to the front stage and laying the groundwork for the Twitter apps to become what they are today.
