My name is Marc Langenberg — I’m an IT specialist with a focus on cybersecurity and cloud solutions, and Founder and technical lead of my creative tech project CosplayGIF.
I’m currently studying Bachelor of Science in IT Security @ Berlin University of Applied Sciences and Technology and also preparing for the Certified Information Security Specialist.
For more than ten years, I’ve been deeply involved in the cosplay and convention community, working voluntarily as a division and team leader at DoKomi Expo in Düsseldorf, Germany from 2014 to 2024.
The unique energy, creativity, and passion of the cosplay scene have fascinated me ever since and continue to influence both my technical and creative projects today.
With over a decade of experience as a photographer and retoucher (for brands such as Ulla Popken, Douglas, and dm), I combine creative vision with technical expertise.
My journey from digital film production to commercial fashion photography and IT taught me how to merge creativity and technology in secure, smart, and innovative ways.
