I can’t get over how fast Erik worked… [I] had no trouble handing him a half-completed design and then showing our product VP the working version in code later that day.”

Let's Work Together

Please Note:

I am currently seeking out UX/UI clients primarily in two spaces:

  1. Cutting-edge physical technologies such as quantum computing, private spaceflight, nuclear/fusion/geothermal energy, etc.
  2. Digital products that bring analytical rigor to improving the world – e.g. effective altruism, evidence-based medicine.

If you – or someone you know – needs design work in this space, please reach out.

I completed Learn UI Design about 2 months ago, and it’s changed my life. My skills are on a whole different level now. Probably the best-spent $1000 of my life. Thanks a lot!”

Milutin Tomic

I'm a UX designer, but since doing Learn UI Design, my visual design skills have improved so much that teams I've interviewed with thought I was a UI designer who accidentally applied to a UX job! I've seriously learned way more about design from Learn UI Design than I did from [my four-year university]!”

Xingxin Chen

The color videos BLEW MY MIND! This is EXACTLY what I’ve needed to learn for years. I could never name it, but you just showed me. I’ve been paying attention to color for decades, and have NEVER seen this ANYWHERE. Thank you, Erik!”

Kelly Kuran
