Hi, I’m CJ. I’m a UI+UX engineer and designer. Here are a few things I’ve built outside of my day job.

Flexbox Patterns

CSS flexbox is awesome, but it introduces many new concepts that can make it difficult to use. I made this site to share examples and source code that will teach people how to build UI components with CSS flexbox. This site got tweeted by CSS-Tricks, Smashing Magazine, and ZURB Foundation.


Take Buffett’s billion

My friend Damien Sutevski and I tried to game Warren Buffett’s 2014 March Madness bet with the public. Kinda goofy but it attracted 21,000 signups and a mention on Nate Silver’s blog, fivethirtyeight.

Neon marketing site

I had the honor of designing and developing Neon’s marketing site when they were pre-round A. Shortly after the launch of their site they raised a $4.1MM round to support their mission of automating the video thumbnail selection process.

Atomic armies

I started an LLC and built this social game in Flash around the time Zynga was eating everyone’s lunch. The game didn’t do so well but it was a heck of a lot of fun (and hard work) to make.

VFX work (previous career)

There’s a global community of visually-talented hackers who build interactive artwork, visual effects, animations, and data visualizations for a living. At an earlier point in my career, I was one of them.
