About me

Welcome to my - kind of - CV. Let me shortly introduce myself. My name is Marco, a full stack developer based in Germany with a huge passion for building stuff for the world wide web. I have 10+ years of experience in building web applications, designing and developing user interfaces and backends.

At the age of seventeen, I build my first website. Since then I'm an enthusiastic developer and indie maker loving to build new things from scratch - coding everything from the backend, to the API, to the frontend. I have made a lot of web and mobile tools in the travel and nomad area before I launched my side projects in the SaaS market in 2018 and 2020.

In the past, I have worked as a freelancer for different clients around the globe and bootstrapped my own company. During my master's studies, I have been employed in the research team for mobile and cloud computing at the university of applied science in Worms. My main focus here was on modern and highly scalable technologies for web and cloud applications.

When I am not outside trying to get the perfect drone shot, I'm the go-to guy at Sleekplan and Sleek.page in my spare time.
