overview
I’ve been working on commercial projects for more than ten years. Today I work as a Software Engineer (MTS) at PayPal in a Zettle onboarding team, leading several initiatives. Before that, I worked as a Full Stack Developer at a streaming service Viaplay. Five years of my career are related to eye tracking company Tobii where I was working on various projects and, at some point, shifted focus from desktop and system programming to Cloud and Web domain. I speak at conferences and meetups, code and read about software engineering in my spare time, and enjoy creating and shipping pet projects.
