Skills

Hello and thank you for visiting my freelancer profile.

Sebastian is my name, and I'm from a small town near Düsseldorf. I've been a graphic designer for over 18 years, with the first 12 spent primarily in the fashion industry. I was primarily responsible for designing and creating prints and patterns for apparel, footwear, and accessories, as well as creative management of small and medium-sized interdisciplinary design teams for companies such as adidas, Puma, Reebok, Jack Wolfskin, and Walt Disney. In 2014, I became increasingly involved in the fields of UI and UX design, and I began to gradually develop online presences for medium-sized and large FMCG companies. Since the middle of 2020, I've only worked as a freelancer, implementing digital projects for companies such as Indeed, Vorwerk, RTL+, Armed Angles, LFDY, VDE, Kachelmann Wetter & Vereinigte Hagelversicherung among others.

My primary focus as a UI & UX designer is on conceptualizing and designing digital products, such as landing pages, websites, APPs, User Interfaces, and UX concepts, but I also have extensive knowledge, experience and skills in design systems, typography, image editing, photo retouching, vector illustrations, branding, and CI.
