About  —

Emil Rosenius,
software developer.

I'm a freelance developer based in Copenhagen. Since 2015 I've shipped code inside large enterprises and product-led companies - with clean architecture, honest communication, and systems that hold up in production. Most of my work sits at the intersection of frontend architecture and full-stack development, from small marketing sites to complex platforms for companies like Microsoft, Novo Nordisk, and Rigshospitalet.

Over the years I've worked across many different industries and team setups. I've led delivery alongside teams of up to 12 developers, and I've owned outcomes solo when that was what the situation called for. That range has given me a good sense of when to keep things simple and when a more structured approach is needed.

Today I work as a freelancer because it lets me stay close to the code and the people I build for. I join your tools, your meetings, and your workflow - and I care about getting the details right.

If you're looking for a developer to help ship serious software - whether that's hands-on coding, architecture, or technical direction - feel free to reach out. I'm always up for a conversation over coffee.
