Experience
Healthcare Website and Patient Portal (Toptal Project)
https://www.northeastspineandsports.com/An MVP of a new web experience for the patient portal. The goal was to completely rethink the patient experience on their website to make it more seamless and enjoyable. As a WordPress developer, I created the front end of the website using the Tailwind CSS framework, which was a great solution for developing the visual part of the site. I implemented the back end using the ACF plugin, one of the most powerful plugins for creating custom fields and relationships between CPTs.
Mundana Travel | Website for a Travel Company via Toptal
https://mundana.com/A website that lists all luxury hotels around the globe. As a WordPress developer, I implemented additional functionalities and custom page templates, fixed issues during the development process, optimized the website page speed, and integrated the GTM and GA4. This project is still ongoing.
RinggitPlus | Blog Website
https://ringgitplus.com/en/blog/Created a pixel-perfect template using HTML and a CSS blog design from Zeplin. The blog contains the main post page with configurable settings, such as editing the categories to be shown, adding more category sections, and customizing a YouTube playlist; an article page with article ratings; a custom CTA section; comment features; and the category page. The website is fully responsive, and I enjoyed the experience while working with this client.
Overwater Bungalows | Website About Traveling
https://www.overwaterbungalows.net/A website about traveling that includes a blog, resort pages, and destination pages, and groups the resorts by destinations. In addition to developing a custom WordPress theme from an XD design, I created the front end, back end, and responsive version of the website.
Price of Travel | Website About Traveling
https://priceoftravel.com/At a glance, it's a simple website. But if you dive into the code, you'll see a lot of custom fields and algorithms that optimize the website speed. I worked on the project as a full-stack developer and created a custom WordPress theme based on the XD design I was given.
The most important pages on this website are the city pages, and there are two types: city travel guide and city travel price. The city travel price page includes a currency converter that allows users to choose their local currency. I used the currency layer API to implement this functionality. This was a great project, and I was happy to work on it.

eMAG Upload | WordPress Plugin
A plugin for uploading products from the WooCommerce store to the eMAG Marketplace in one click, using the eMAG API, which has a lot of options to make the plugin more customizable. The administrator can upload one or more products at a time, and they can select the categories in which to upload the products. I developed something similar (OLX Upload), but the main difference is that this plugin sends statistical data back to the website.
WordPress Plugin to Filter Products
A plugin to filter products for WooCommerce that creates a filter based on the specific attributes that have a custom name structure. It collects the specific attributes, groups them, and displays them on the options page. The user can set a custom title for these groups and choose how the terms should be displayed as radios or as checkbox fields. The filter can be inserted on the front end by using a short code, and it will be displayed on product archives only.
WooCommerce Shop with Landing Page
A WooCommerce shop I created from a custom design. The shop functionality is built on the WooCommerce Storefront theme. I integrated shipping based on the product weight and EuPlatesc, the local payment gateway.
House Selling and Rental Website
A website that displays a list of properties according to options selected from the filter. The properties can be added, edited, or deleted from the admin panel, and they are grouped by categories, regions, types of use, and more. I implemented the design and functionality of the website, using a custom builder. Developing this website was a great experience.
Presentation Website for Professional Translators
https://elgtrad.com/enAn HTML and CSS template integrated with WordPress. All text on the website is dynamic and can be modified by the admin using the ACF plugin. I created a custom WordPress theme to integrate the HTML template and integrated WPML and WPML String Translation to make the website multilingual.
Real Estate Presentation Website
https://www.partnersavenue.ro/A simple presentation website I developed based on the PSD design. It contains a landing page with a few sections, a contact page, and a portfolio page. On the portfolio page, I implemented a filter that groups the portfolio items by year, using JavaScript.
Website Change and Improvement Implementation
https://80000hours.org/I created a new shortcode that generates a section with a summary container and a button to open the details section. The shortcode accepts a few parameters, reads the content between the tags, and can be rendered multiple times with different content.
I added a footer to the Algolia autocomplete results that contain a link to all the results page. The labels are composed of static text, and then find the results count.
