Reialesa

https://reialesa.com
A portfolio website with a custom theme. I was the back-end and the front-end developer on this project. The client provided the design with detailed instructions made in Adobe XD and I converted it into a WordPress theme. I used Ninja forms for the contact form, Mailchimp for the newsletter and the admin was built using Advanced Custom Fields. Other than that everything on the site is custom built.

Custom Products for WooCommerce

Worked on my own personal project, which is an extension for WooCommerce that adds a new level to the product-attribute hierarchy. The plugin includes multiple shortcodes, a WYSIWYG SVG image editor, customization fees, attribute images, and much more.

WP Dev Helper

https://play.google.com/store/apps/details?id=com.labdog.wpdevhelper
This is an Android app that I created with Android Studio and Java to track statistics, ratings, and support forum for my (or any other) plugins published in the WordPress plugin repository. It obtains live data from the WordPress API and presents them in a mobile-friendly way.

Kozmetična sobica pri Nini

https://www.kozmeticna-sobica-pri-nini.si/
I designed and developed this website for a beauty salon owner. I built it with a Divi child theme; I also made the design, created all effects (parallax, transitions, etc.), the accordion section on the homepage, and more.
