Hi there 👋

My name is Markus and I am a open source enthusiast since 2008 .

I am the developer behind cs2pr, phpstan-dba, rexstan and a few more projects.

For fun and educating myself I actively contribute to various projects - PHPStan, filp/whoops, sabre/dav, stomp-php, propelorm - to name a few of them.

I am curious and reading a lot regarding latest web technologies, web standards and browser development. My passion is working on performance problems and figuring out crazy bugs 🐜.

In case I was able to help you out with my contributions in the past, please consider supporting my work with your sponsoring 💕
