I added a new project to my Contra profile. I was the Design & Developer on the project and acted as a Design Engineer.

I used Figma and Cursor/Claude to build the MacOS app.

New on Contra 👋 I am Erlend. I write short-form scripts for TikTok, Reels, and Shorts, and I build content systems for DTC and B2B brands. Most videos do not fail on production. They fail in the first 3 seconds. That is the part I focus on most. Open to UGC scriptwriting and content strategy projects. What are you working on?
