Content Snapshot | Drupal 8 Module

This module gives you the ability to export/import a website's content from/to YAML files. Great tool for automation, as it allows websites to be dynamically built from the code and content repositories for development and staging purposes.

Content Fixtures | Drupal 8 Module

Do you want to build a running website straight from your repository, but you realized that you have to get some dummy content from somewhere? Search no more.

This module will give you an API to program your own content generators, that you will be able to run with one command, and fill your website with the content required either for development or presentation.

Entitypoll | Drupal 7 Module

This is a contributed module that I started working on some time ago, with the intention of making a poll system with a clean API based on entities.

Entityform Email Confirmation | Drupal 7 Module

This module provides elements for Rules, which will allow you to set up the confirmation of emails that are sent to your website by using Entityform.

Entity Reference Select View Per Context | Drupal 7 Module

This module provides a new selection handler for Entity Reference that allows the use of a different view for generating options based on context.

Block i18n Config | Drupal 7 Module

This module provides an API that should help with integrating your custom block configuration with i18n so it will be translatable on the block translate page just like the block title.

i18n Migrate | Drupal 7 Module

This project is intended to provide classes for use with the migrate module; to help with the migration of internationalized Drupal core content.

Transferuj.pl | Drupal 7 Module

I integrated the Transferuj.pl payment gateway with the Payment API; it may have already become obsolete.

Other Drupal Contributions

A Selection of Projects:
• Developed and proposed a unique solution to the problem of Drupal's Layout Builder limitation of layout structure.
• Contributed multiple patches to core bugs.

Betomat

https://betomat.netlify.app
Application based on a custom CKEditor 5's plugin, helping writers to clean up their writing style by highlighting different pronoun groups in their writing. This application has been made for the Polish language, where pronouns appear frequently and are often overused. Writers might not be aware of the pronoun clusters they produce during writing until it gets highlighted for them. This app helps them in that regard.
