I design what you see and build what you don’t. The site, the form, and everything behind it that makes things happen on their own.[*]

[*] By day I’m a developer at Juristic, where I was one of the first hires. On the side I build websites and web apps.

What I build

  1. S01

    Websites

    Sites that look like you, not a template. In Danish, English and Spanish.

  2. S02

    Web apps

    Booking systems, tools and anything that’s outgrown a spreadsheet.

  3. S03

    Automation

    Boring work that runs itself. Forms, emails and systems that talk to each other.

  4. S04

    Upkeep

    Fixes and new features when you need them.
