More than half of these are fake though. I would be more interested in seeing how people solved real complex UI.
Your opening paragraph is on point. It's how I feel. I've been building feature rich, data complex, "business needs" driven analysts dashboards and web applications for the last 5 years. I get that same anxiety that you described every time I'm on dribbble
i can confirm that my work in this list is part of a real product, but utterly unimpressive and meaningless without any context.
I'd argue that it isn't unimpressive or meaningless. The point of the article was to highlight the handling of an interface that has a lot of moving pieces and the potential to be visually confusing.
I used the term UI in the title purposefully because this is inspiration more for that last phase of a project, implementing hierarchy in a form or using color to separate objects in a table.
We all have very different design problems to solve, but design principles and patterns are common, which is where gaining inspiration from the UI work of others can be valuable.
I worked for a couple of years at an extension project between the Federal University of Santa Catarina and the Brasil's Federal Ministry of Health as a digital product design intern.
At the time, I was assined to re-brand and re-design an entire web app/system called SISMOB (Sistema de Monitoramento de Obras), which had the purpose of monitoring the constructions — between the Federal, State and City spheres — of the Federal Ministry of Health. It was my first experience as a digital product designer — which included UX/UI, interaction, etc — and I also struggled so much with some "screens", because I couldn't find any sort of "real" complex digital product inspiration.
Anyways; I thought I could try to help you guys by showing the designs I did.
Hope you understand them, because they're all in Portuguese.
Yeah none of these are that complex, and a lot of them are fake. It's an interesting topic though. If you want complex UI look at specialized tools that need to handle specific workflows.
Travel sites are usually good examples. One of the most complex UI I worked with was a reservation flow for a cruise site.
