Available to hire
I’m a senior frontend developer based in Denmark with over 25 years of software development experience, including 15 years in technical consulting.
My work spans public-facing web sites as well as complex internal business web applications. Along with hands-on UI development, my focus is also on making the foundational technical choices needed for a successful frontend solution — without making things more complicated than they need to be. Simplicity and maintainability are guiding principles for my work.
When joining existing teams, I adapt easily and focus on predictable, self-managed delivery, while helping out teammates and filling in gaps where needed.
Since starting as a freelancer in 2022, I have delivered projects for major domestic and international organisations, including the United Nations, Jyske Bank, and Denmark’s largest construction and contracting company, Per Aarsleff.
