Hi, I’m Sandy Dähnert

I am a UX/UI designer from Cologne. For more than 10 years I’ve been helping brands to design user-friendly, accessible and (since 2018) ecologically sustainable websites, apps, online shops and other digital products. Because we as designers and companies have a responsibility. And because, to be honest, it has a lot of benefits.

My work is my absolute passion, especially when it gets tricky and complex.

I was honored to work in amazing projects for Adobe, Unicef, Telekom, Vodafone, Shop Apotheke, Langenscheidt, Recoupling, Eurorad, Klugo, DKV and various banks, insurance companies and car manufacturers. Will the next project be one with you?

Feel free to contact me to chat or to request a look at my portfolio.

There’s more if you want

What’s the web’s footprint?

Every mouse click starts a dialogue with data centers, that run 24/7 on energy and are cooled down with huge amounts of water. Telecommunication networks and end-user devices add to the massive needs of energy and emit all-together more than 830 million tons of CO2 per year, estimates rising.*

My vision …

… is a green, climate friendly web with happy users, super fast websites, healthy and loving communication, high accessibility, diversity, green patterns instead of black patterns and brands and designers that love their digital products and jobs. In balance with nature.

With green design, your website gets a real kick in terms of SEO, minimal loading times, sustainable consumption and happy users. Sounds quite nice, doesn’t it?
