About me

I have 7 years of experience in web development. I lead small development teams for about 4 years now. For the last 1.5 years, I’ve been a part of the team working on a project focused on developing a 3D printing application with interactive model visualisations (and thus a need to dive into the mathematics of it all). Previously I was building a rather complex CRM/manufacturing management software. I'm generally a quite flexible person interested in learning new things. Love working on startup products and not a fan of burocracy-heavy enterprise projects. Also, I'm a jazz piano player.
