👋 Hi there

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

Markus Staab - open-source lover, creator of staabm/phpstan-dba, staabm/phpstan-todo-by, rexstan and rexfactor.

I am one of the top contributors💫 to PHPStan and Rector. 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:

@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.

If one of those open source projects is critical for your business, please consider supporting my work with your sponsoring 💕. I am also available for paid support of PHPStan and related static analysis tooling.
