A bit about me

My name is Matthijs Lanser. I'm a freelance software engineer based in Prague, Czech Republic. I have a big passion for turning ideas into real products. Over the last few years, I've been able to do this while working on and leading multiple complex international projects.

In addition to cooperating with various companies as a contractor, I've built several SaaS applications of my own. The projects I worked on range from simple landing pages, like this one, to complex SaaS applications used by hundreds of thousands of people.
Across these projects, I've gained a deep understanding of software engineering and business needs.

My skills range across the whole software development process. From the prototyping/design phase to building a fully-fledged API that can be used by a single-page application. All the way up to hosting while keeping customers up to date using product management tools and meetings.
