Hi! My name is Maciej. I’m a full-stack web developer from Poland, a certified expert on Codeable since April 2018.


What I can help you with

Web development is a wide area, and while I have worked on many types of web projects in my career, I choose to specialize in the ones which I enjoy doing the most.

I would love to help you with:

  • Plugin Customization (WooCommerce, WooCommerce addons, Gravity Forms, The Events Calendar and more)
  • Third-party API Integrations (form submissions, POS, inventory catalogs and more)
  • Plugin Development (add custom functionality to your WordPress website)

Below you can view some samples of my work.


MyClassroomscreen Demo

MyClassroomscreen – a virtual blackboard for teachers. The application provides a suite of tools to teach and manage a class. You can see it live on MyClassroomscreen Demo.

WooCommerce Timed Checkout

WooCommerce Timed Checkout on Every Day Original

WooCommerce Timed Checkout is a WooCommerce add-on I made exclusively on a client’s request – an e-commerce store owner who wanted to smoothen the checkout experience for his customers who purchased unique products on his site. Whenever a customer adds a product to the cart, a timer will be added and the product will be locked for that customer for the given time period. In the meantime, other customers can sign up for the waitlist in case the first customer doesn’t buy the product. You can see the functionality live on Every Day Original.

Advanced Product Options

Advanced Product Options on Feuerzeuge24.ch

This is another exclusive WooCommerce add-on I have developed. The customer needed a product options plugin for his network of sites, with very specific needs as to how the options affect the price. None of the existing plugins quite matched the requirements, so I developed a custom one. This plugin also adds the ability to download a pdf offer of the customized item. You can view a working example on Feuerzeuge24.ch

Maciej was very thorough in writing the specification of the task, giving me confindence in his ability and attention to detail from the start. He was very helpful throughout and always responded to messages in a timely manner. The plug-in works great - as specified. Nice Job!

It was an absolute pleasure working with Maciej! He helped me customize a Gravity Form in Wordpress by building a custom plugin for me. I would happily use his services again!
