Founder & Developer · calculations.tools
I have worked with SEO and software development since 2017, helping businesses grow their online visibility across multiple markets and languages. My work sits at the intersection of technical SEO and data analytics - building systems that are both measurable and durable.
Calculations.tools grew out of a personal frustration: too many online tools are engineered to extract value from users rather than provide it. I built this site to be the opposite - a resource that genuinely helps people with everyday tasks and stays free indefinitely. Every calculation runs locally in your browser; nothing is transmitted to any server.
Before my career in digital, I was a professional hockey player competing in Denmark and Germany. The discipline and focus that come with professional sport translate directly into how I approach development and SEO - methodical, detail-oriented, and built for the long game.
Outside of work I travel with my family, hike in the mountains, and explore Scandinavian nature with my wife.
