Hi, I'm Jesper

Developer in Nordic financial services. Based in Denmark with a wife, two kids, and three cats.

synsyst = synergistic systems.

Most of my code lives in private repos for work, so the public side of this profile is sparse on purpose. The contribution graph tells the real story.

Currently building

• A stock options suggester for my own portfolio. Retail investor side project, somewhere between "actually useful" and "excuse to code on weekends"
• Most of my development these days happens through Claude Code. It's been the primary IDE since Sonnet 4.6 made it genuinely good

Sometimes appears in public

• Small fixes and PRs on tools and libraries I use day to day

Long game

Game dev. Not there yet, but it's where I'm headed when the timing works.
