JZ Jeff Zych

Hi, I’m Jeff.

I’m a designer, developer, and writer based in San Francisco.

I’m currently Head of Design at Optimizely. Before becoming a manager I was a Product Designer and a UI Engineer.

Before joining Optimizely, I earned my Master’s degree at UC Berkeley’s School of Information, where I studied human-computer interaction, usability, and behavioral economics.

I’m also a tennis player and musician (guitar/bass/drums).

This is my personal site that I use to write about design, code, A/B testing, and other topics that interests me. A few of my most popular posts:

You can find me on Twitter, Instagram, Medium, LinkedIn, Github, and Gmail (jlzych@).
