PHP Development

PHP Developer Simon Köhler

From 2000 to Today – Been There, Built That

Hey, I’m a PHP veteran – I started developing back in 2000 (yes, when modems still made screeching sounds). Since then, I’ve worked with countless internet agencies across Germany, crafting everything from multilingual enterprise sites to dynamic frontend magic. If you're looking for a PHP Freelancer who’s seen it all – that’s me.
