Born on 6th October, 1982
Lives in Copenhagen, Denmark


I’ve been a web developer for more than 10 years. During my career, I’ve been responsible for building awesome digital products together with great team members – from startups and companies at earlier stages, to big companies that lead the market like I’m currently working at Danske Bank in Copenhagen, as Senior Software Engineer, making part of one of the biggest fintech companies in scandinavia. I’m an experienced full stack developer with a strong foundation in front-end, which I learned while the Javascript language conquered the world. My career has been built of learnings from different projects and this way I’ve acquired experience with the most used programming languages such as Javascript and their main frameworks, like React.js, React Native and Angular.js, as well as backend languages like Node.js, Ruby, Java, Python and PHP. This flexibility creates an opportunity to contribute with a variety of open source projects and cross team initiatives. I love sharing my learnings with the community on my blog ( and I published the Mobile First Bootstrap book by Packt Publishing in December 2013. I’ve participated as speaker in technology conferences such as Qcon (Worldwide) and FISL (International Open Source Foundation). I usually talk about web, mobile, test driven design, performance and user experience. I used to work part time in personal startup projects in order to learn how to launch digital products iteratively in a real setting. Beyond the limits of the web, I like to explore the internet of things, programing with Arduino and microcontrollers. I would like to work in an open environment, a place that embraces continuous delivery and collaboration, that can impact the society with technology.
