I'm Lukas Lönnroth, a software and integration developer based in Ekenäs, Finland. I founded Muuk.io to do what I've always done, solve real problems with technology.
I didn't take the usual route into software development. Before I wrote code professionally, I worked as a seaman on cargo ships in the Mediterranean, the Baltic, and the North Sea. It's not an obvious starting point for a tech career, but in a way it shaped how I work: you learn to be self-reliant, to solve problems with whatever's available, and to keep things running even when conditions aren't ideal.
The truth is, I was already programming on those ships. I'd been building websites since I was 15, and computers were always where my head went when I had time to think. Eventually, I decided to stop doing it on the side and make it my profession. I went back to study computer science, and I haven't looked back.
That was over eight years ago. Since then I've worked across some varied industries. Building card payment backends in the banking sector, developing integrations for law firms, working on fintech platforms, ERP systems for food production, and most recently a platform for listed companies. Alongside my employed roles, I've always consulted independently. Muuk.io is the natural evolution of that, bringing everything together under one roof.
Over eight years I've had the chance to work on complex, high-stakes software across a range of sectors. That breadth matters — it means I've seen how different industries approach technology, where the common pitfalls are, and how to build things that actually hold up in production.
I'm a one-person operation, which means when you hire Muuk.io, you work directly with me, not a project manager who relays messages to a developer you never meet. I think that's a feature, not a limitation.
I take on a focused number of projects at a time so I can give each one proper attention. I'm direct about what's possible, honest about timelines, and I'd rather have an uncomfortable conversation early than deliver something that misses the mark.
I work in English, Finnish and Swedish, and I'm remote-first with availability across EU time zones.
I started Muuk.io because I wanted to work on interesting problems for clients who care about the outcome, without the constraints of a single employer or a single industry. The consulting I'd done on the side over the years had always been the most satisfying work: direct relationships, real impact, and complete ownership of what I delivered.
