Nicolas Russo-Larsson


From concept to production, I help companies design and build products following an agile process:

  1. Start with something testable
  2. Make it usable
  3. Refine until it’s lovable


I mock up designs with Figma / Sketch and then use HTML / CSS (preferably leveraging Tailwind) to deliver production ready interfaces. I often contribute directly to an app's codebase and can manage full component systems. I recently worked on Lifeforce, Polymarket, Invelo, and StoryScout. To see earlier design work navigate to my previous portfolio.


I'm a co-founder and the designer of Markup Hero — a web-based screenshot and annotation tool. With Markup Hero it’s easy to capture ideas with the scrolling screenshot feature, communicate clearly with the annotation tools, save time with editable share links, and stay organized with full history. You can even annotate multipage PDFs, Google Docs, Sheets, and Slides. Try uploading an image and start annotating in 60 seconds or less.
