    Software engineer

    Sweden

    Summary Ever since I can remember technology has been an important part of my life, this has taken me from founding my own small technology company back in Sweden to working on projects all over the world. This same focus on technology also allows me to have a broad understanding of how technology is evolving and it has given me the ability to widen my knowledge which is now spread across several different kinds of technological areas. References will be provided upon request. Specialities I am an experienced developer within the mobile sphere having built both back office software as well as fully fledged content delivery and billing solutions for some of the biggest carriers in the world. Ive had several titles in top lists in the apple appstore and on carriers across the world. While mobile has been my main focus the last couple of years my base lies in web where I have developed solutions to allow companies of all sizes to have a presence on the web. I’ve built systems and websites for everything from small local companies to big global companies. For the last couple of years my focus on web has been towards Ruby on rails using a BDD philosophy having finished both big and small sized projects by successfully leveraging cucumber acceptance tests and story writing as well as unit tests based around rspec. While being a partner in different businesses I have also gathered skills in business planning and management.
