Hey there.

I would like to introduce myself.

As you've probably noticed by now, my name is Jannik. I'm currently living in sunny Malta and I'm a freelance software developer. Originally I'm from Germany. I was born there in 1993 and used to live close to the northernmost city of Flensburg. After finishing school in 2012 I escaped home and moved to Hamburg, where I joined a company called InnoGames GmbH for an apprenticeship as Computer Science Expert within the subject of Software Development - that's how the Chamber of Commerce calls it, but basically I was training to become a full-stack developer.

I finished the apprenticeship in January 2015 and InnoGames offered me to stay and continue working for them as a software developer. So I did until August 2015 when I was hired by a company called Infovations AG - based in Zurich. I moved to Switzerland, worked a little more, then eventually decided to move to Malta and become self-employed in March 2016.

I spent the last years working with numerous clients including InnoGames GmbH, Modix GmbH, hanseflow UG and UB1st GmbH from Germany as well as Apson KG from Austria. I also had the chance to work on projects for a few high-profile clients, such as Audi and Deutsche Telekom.

What I do.

Usually I'm hired by companies to work on web development projects, but I'm also working for end customers. You need a website, a blog or a web application? You can contact me by writing an e-mail to hello@janniklorenzen.de to discuss your idea and get a quote.

Recently I started offering training and consultation services as well. You can see details about these services on the respective pages.
