I worked on the Die Mitte WordPress ecosystem, which included a WordPress Multisite network and stand-alone WordPress installations supporting more than 300 websites.

I developed a custom plugin from scratch to retrieve and synchronize people data from the centralized Hitobito database provided by Puzzle ITC. The plugin stored people as a Custom Post Type, managed profile data using ACF, and supported WPML programmatically by creating content in the correct language and linking translations.

I also developed a second custom plugin for cross-site content synchronization. Administrators could connect source websites running the same plugin, browse and select posts or pages, and keep imported content synchronized with the source. The plugin also handled WPML languages and translation relationships automatically.

I worked across both multisite and stand-alone architectures, supported multilingual functionality, and maintained full and light versions of the main theme.

The project demonstrates experience with large-scale WordPress architecture, Multisite, custom plugins, WPML, ACF, external data integration, and multilingual content synchronization.

I developed ChatHearth, an AI chatbot plugin for WordPress and WooCommerce that helps visitors ask questions about website content, compare products, and choose the right products based on their needs.

The plugin uses OpenAI through WordPress Connectors and includes a built-in RAG knowledge base that indexes selected pages, posts, products, custom post types, and taxonomies. Embeddings are stored directly in the WordPress database and updated incrementally when content changes.

ChatHearth can answer questions about the page a visitor is viewing, provide source links, display product recommendations, compare WooCommerce products, and allow users to add products to their cart directly from the chat widget.

It also includes configurable appearance settings, conversation history, Markdown responses, rate limiting, content moderation, optional reCAPTCHA protection, a kill switch, and site-wide usage controls.

The plugin is publicly available on the official WordPress.org plugin directory.

I worked with MediaTech Ventures, a media startup incubator running a complex WordPress community and learning platform built with BuddyBoss, BuddyPress, BuddyForms, LearnDash, Divi, HubSpot, and several third-party services.

My work included integrating BuddyForms registration forms with HubSpot so new users and custom registration fields were automatically synchronized with the CRM. I also refactored existing BuddyBoss parent-theme customizations into a child theme to make future theme updates safer and easier to maintain.

In addition, I customized the BuddyBoss NewsFeed to display recent community activity and introduced custom activity events required by the platform.

For comment migration, I used the OneAll LoudVoice API to export externally stored comments and developed a custom WordPress plugin to import them into WordPress while preserving comment/reply hierarchy, author details, original dates, and essential metadata.

The project combined WordPress development, CRM integration, BuddyBoss and LearnDash customization, API-based migration, theme refactoring, troubleshooting, and custom plugin development.

• To address a specific need, I created a custom "Investment Calculator" feature for properties listed for sale on the website. This tool can be accessed when viewing the details of any property, such as this example: https://www.jacbon.eu/property/luxury-3-room-house-for-sale-in-centrum-denia-in-costa-blanca/

• The "Investment Calculator" was meticulously crafted using Vue.js, allowing for dynamic interaction with all the fields. Users can control and adjust values effortlessly through intuitive sliders.

The UX/UI of the client's website. I worked with the client to create the UX/UI of their website. I used Adobe XD, and here you can see exported images of the pages: bit.ly/creos-ux-ui. I also worked on the development of the website. I built the website using the Gutenberg editor and used the GeneratePress theme (generatepress.com) as the basic theme because it is a lightweight WordPress theme focusing on speed, stability, and accessibility. In addition, I used the GenerateBlocks (generateblocks.com) plugin to add some basic blocks to Gutenberg. The plugin is a small collection of lightweight WordPress blocks that can accomplish nearly anything.

In addition, I developed ten custom blocks to match the clients' UX/UI designs. The blocks include the Toggle switch, Testimonials, Tabs, Icon Box, Flip Card, Featured Box, Facts Carousel, Counter, Cards Carousel, and Accordion.

I also created a simple, special user manual to help the client manage his website after finalizing the project. Here, you can find a copy of this manual: bit.ly/creos-manual.

• I successfully integrated Gravity Forms with Stripe for donation support on this page:
• https://thevarsitycollective.com/donate/

• I helped fixing several issues with the following form:
• https://thevarsitycollective.com/vbclub/

• I ensured one-time and monthly donation options, with funds sent to separate Stripe accounts based on user choices. Additionally, I enabled automatic receipt generation and resolved layout and responsiveness issues in Gravity Forms.

I worked with BuildPalestine to complete the following tasks:
• Building custom blocks in Divi to allow them to add complex content based on their designs.
• Helping them set up their Strip account, connect it to Donorbox, and integrate the form on their website.
• Fixing some Divi-related issues, like performance and display.
• Fixing their security issue and installing and setting up Sucuri service.

This website was built using the Divi page builder and the DiviEstate theme. I revamped it using Gutenberg custom blocks, GeneratePress, and GenerateBlocks. I built 20 dynamic Gutenberg blocks with React to make the final result 100% pixel-perfect as the designs. The custom blocks included an advanced property search, property carousels, and custom single property pages with affiliate buttons, galleries, and standout features. Property features were organized with custom taxonomies, improving database response.

Additionally, I used Gutenberg reusable blocks for articles, offering content flexibility. Property locations were structured hierarchically for precise filtering, and customizable property status/types enhanced the front-end display. The revamp improved performance, user experience, and content management, showcasing the power of React and Gutenberg Blocks in web development.

Extended WooCommerce products by adding two custom taxonomies and one custom field that was added to a PDF.

Migrated old product information, images, and variations to the new website with the "WooCommerce Product CSV Import Suite" plugin.

Set the "YITH WooCommerce Request a Quote" plugin so visitors can add products to their request and then send the request to the website admin.

Created an advanced search form that uses all 11 custom fields, the product title, and SKU to filter the products.

Added the FAQ page as accordions.

I created a sticky sidebar for the single project page that sticks to the screen while users scroll down.

Integrated the product zoom plugin with the functionality of popup slideshow images. When users hover on a gallery image, the image will zoom and move based on the mouse movement, and a plus icon will open the image in a popup slideshow.

Customized my account page content, links (endpoints), and the checkout page messages and layout.

Set up the ticketing system on the website with the Event Calendar plugin and WooCommerce so that the website admin can sell tickets for events based on several locations and dates.

Created an auto-menu filler in the footer.

Fixed several plugin conflict issues that were causing the WordPress control panel to stop working properly.

• I created a plugin to filter the zip codes on the checkout page; if the zip code does not pass the filter, the client email is automatically sent to Mailchimp API.

• The second plugin I created was a cron job that runs every day to check the old orders that remain in specific status for a specific amount of days and automatically create tickets for them on Zendesk using the Zendesk API. The tickets are made once per minute to avoid overwhelming the Zendesk API.

• The third plugin was an update on a ticket creator plugin to allow the users to attach images to their tickets. Here I checked the user email and order ID and used the WordPress nonce field to make the form as secure as possible. The user can create a ticket and attach several images if the order is found.
