LoveOne builds systems that last – smart and step by step.
Hi, I'm Mattias!
LoveOne Consulting AB is my consulting company. I hold an M.Sc. in Electrical Engineering from KTH and have been building systems since 1999 – as an architect, tech lead, scrum master and developer. I'm at my best where technology and business meet: finding the simplest architecture that can handle tomorrow's demands, and then building it in small, safe steps.
I'm happy to take on assignments as an architect, tech lead or fractional CTO. I speak Swedish, English and Japanese.
LoveOne in four characters
Architecture
Building systems that hold up as they grow. I have designed and built scalable platforms in fintech, gaming and the automotive industry – from the first sketch to running in the cloud.
Experience
More than 25 years of software development, from Java servers in 1999 to cloud architecture on AWS, GCP and Azure. I've seen most of the mistakes – often from the inside.
Iterative
Small steps, early value, constant feedback. These days with agentic AI development, which lets a small team deliver like a large one.
Trust
You get me – no middlemen. The person giving the advice is also the one writing the code.
Selected assignments
A selection of assignments. I'm happy to send a full CV.

How I work
Most IT projects that fail try to do too much at once. Instead, I start with an overview of the business's challenges, pick the most pressing problem and build the smallest solution that delivers real value – often within a few weeks. From there we continue in short iterations with close feedback, so the system grows with the needs and the architecture holds all the way.
