UI Critic by Usercall
Many UI issues I’ve seen aren’t visual problems but unchecked assumptions about users.

Once UI 1.5Dec 2025 · once-ui.com · ▲302When I started my career and built my first design system, I was beyond excited.

In the next job, I did it again, then at the following job, again… And no matter which company I worked for, 80% of the design system was the same. I’ve decided to work full-time on the design system I’ve always wanted, and today I’m launching and open-sourcing it.

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
