about petter carlsson


I am an imaginative coder with a passion for latin american dance and martial arts who spends his weekends volunteering at a cat shelter in Stockholm, where I am based.

A passion for coding led me to pursue web development after 8-years of working as an SEO and Web Analyst. The thrill of finally getting a piece of code to work after hours of frustration and the challenge of finding creative solutions to problems are what I love most about coding.


web development

The appearance, usability and accessibility of your website is more important than ever. I develop client-focused, customer-centric, solutions for both the front end and the back end to help you deliver tangible business results.

web analytics

I work with clients at every stage of the measurement lifecycle, from Google Analytics audits, strategy and configurations, to advanced reporting setups. I’ll also find the goals, user flows and KPIs that really matter for your online business.


Don't let organic search be a missed opportunity to increase revenue and brand awareness. Whether it is optimising the ranking of YouTube videos or ordinary web rankings I can help improve your organic performance.
