The freelance developer clients keep for years.
Hi, I'm Per, a full-stack developer in Denmark. For the past 10+ years I've shipped web and mobile products for fintech, biotech, climate tech and SaaS companies. Most freelancers hand over and leave. My clients bring me back: my average engagement runs over three years.
If it's a two-day fix or a two-year partnership, you get the same care.

Selected work
Clients keep me around. Here's for how long.
Long-term engagements in industries where mistakes are expensive. Every engagement I can talk about, longest first.

The person behind the code
Why I work this way.
I'm Per, a developer from Denmark who has spent more than a decade building for the web and, more recently, for iOS, iPadOS and Android with Expo. I have been an employee at a fintech company, a partner in a startup, and for the last several years a freelancer for accounting, biotech, climate tech and construction companies. That mix taught me that the best code is the code that solves the business problem and doesn't wake anyone up at night.
I don't start coding until we both agree on what the goal is and why it matters. Once we do, I move fast, I am honest when I think there is a better way, and I stick around after launch. I enjoy long-term partnerships most, but I don't shy away from smaller tasks either. If it is a two-day fix or a two-year engagement, you will get the same care.
Outside of client work I build my own products, like Tiltiden and Ønsker.dk, and tinker with Arduino, Godot and whatever technology happens to catch my interest that month.
Process
How we'll work together.
Intro call
A free 30-minute call where you tell me about your project, goals and constraints. I ask a lot of questions and tell you honestly whether I'm the right fit.
Proposal & estimate
You get a short written proposal: scope, approach, timeline and price. Fixed price for well-defined projects, hourly or retainer for ongoing work.
Build in the open
Short iterations, working software early, and a weekly update you can actually read. You see progress and can change course before it gets expensive.
Launch & support
I handle deployment, hand over clean documentation, and stick around for support and further development if you want me to.
Engagement models, what to expect each week and practical FAQs
Have a project in mind?
Tell me about it: what you're building, roughly when, and what a great result looks like. I usually reply within a day, and the first call is always free.
