Hello, I'm Paul

I'm a developer with over 12 years of experience in web application programming. For the last 5 years, I have been working mainly with WordPress and WooCommerce on the backend and frontend. I'm also skilled with MVC frameworks like Laravel or Symfony 4. I use this knowledge to build custom solutions for Wordpress and WooCommerce apps. I develop applications like social websites, e-learning websites, schedule apps, company websites, e-commerce stores and websites from scratch or based on third-party plugins and themes.

I'm also skilled with Wordpress theme customization and have a full understanding of RWD. My coding style follows the WordPress guidelines - which means I always try to make sure the client can upgrade the WP core and all plugins without messing up the individual changes.
