Hi there 👋

My name is Markus Staab, a open source enthusiast since 2008 ✨.

I am one of the top contributors💫 to PHPStan, Rector, Infection and PHPUnit. It's likely you read my name in the changelog or release notes somewhere.

Below you can find a list of my personal contribution highlights:

• A mixed type PHPStan journey
• @param-out implementation in PHPStan
• type inference for regular expressions in PHPStan, see also my blog post
• @require-extends and @require-implements in PHPStan, see also my blog post
• non-falsey-string type in PHPStan, see also my blog post
• PHPStan sprintf()/sscanf() type inference, see also my blog post
• Endless pull requests to improve performance and efficiency in PHPStan and Rector
• Hundreds of bug fixes in PHPStan, Rector, PHPUnit, Composer…

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

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