I just celebrated my 3 years at OmniSci (formerly MapD). Looking back, my biggest highlight was to move from Frontend engineering to Product design. 22 years ago, the same year I founded my UX design company BioDesign, I started teaching programming, so I always had both interests.
My first project in that new role was to convert the app to dark mode. I always vaguely dismissed the request for dark mode UI as a trend. But then I got a very specific use case: the condition for our app to be displayed on the giant screen of the NVIDIA GTC conference was that it needed to be in dark mode, light mode simply blasts way too much on these giant screens.
I still need to learn more facts about the benefits of dark mode. But at the end of the day, a big part of making our users successful is to make them happy. We delivered dark mode with the next release of OmniSci Immerse and it was a great success. So I have to thank a giant screen for forcing me to learn how to properly design dark themes.
