Hello, I'm Martin.

I'm a freelance web developer based in Stuttgart & Freiburg, Germany. I plan and develop responsive websites, web-applications and complex distributed systems of all shapes and sizes.


Research, climbing and traveling is what I do.

My name is Martin Lowinski and I'm a software developer based in Stuttgart & Freiburg. Currently, I'm enrolled in a PhD program at the TU Berlin and Robert Bosch, working on embedded real-time software. Besides that I love building applications for the web.


My research topic is about parallelizing real-time software for the automotive industry. The increasing complexity of automotive systems requires more computing power, which can be provided by e.g. multicore architectures. To fully benefit from this architecture, automotive software has to be parallelized efficiently while satisfying all real-time constraints.

Web / Freelancing

I am working as a professional web developer since 2008. I create and build websites from the ground up using established standards and great technologies. The web is a fascinating place and if you have a great idea for a new project, contact me and let's grab a coffee.


I am currently available for new projects.


These are some of my freelance projects.
