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.
Car Insurance Web Application - Compara Asigurari
https://compara-asigurari.ro/I developed a quote generation system that collects user input, like personal details, vehicle information, and coverage requirements. It calculates insurance quotes based on that data.
I also integrated with insurance broker API to retrieve accurate and up-to-date pricing and policy information. This integration ensures that users receive the most relevant quotes and policy details.
I've built a comparison engine that can display multiple quotes side by side, enabling users to compare coverage options, premiums, and deductibles easily.
I also then implemented an online application process that captures user information and guides them through the steps required to complete the purchase of their chosen insurance policy.
I Integrated a secure payment gateway to facilitate online premium payments. I ensured sensitive payment information was handled safely and compliant with industry standards. I also created WordPress to allow administrators to update and manage website content, including articles, FAQs, and educational resources.
The website is responsive and optimized for mobile devices, providing a seamless user experience across various screen sizes.
I also then implemented strong security measures and data encryption.

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.
Radius Analytics - Company Website
https://radiusanalytics.co.uk/A WordPress website created using Elementor block builder. The first page hides a secret mesh of zero and one that changes their value assisted by a small red sparkle.
The mesh is uncovered when hovering the RHS image of the first section. The website integrates a lot of custom JavaScript animations, as well as Lottie animations that have been created using Illustrator and After Effects. The design was inspired by the client and created following the client's requirements.

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.

Model Calibration - Radius Analytics
https://modelcalibration.com/A black-on-white website design that is focused on its content and information. I designed a website in black and white to create an elegant and timeless aesthetic, where the absence of color allows me to focus on ideas the client wants to share with the website readers.
It exudes a sense of sophistication, balancing simplicity and sophistication to showcase content with striking visual impact.

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.
Translation Agency in Bucharest - Enlightening Languages
https://elgtrad.com/en/An 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.

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.
Real Estate Website - PartnersAvenue LLC
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.
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.
Simplified Rental Experience Website
The website is easy to navigate, with a clear layout and intuitive design. Users can browse and search for available rental properties with detailed descriptions, high-quality images, and location information. Users can refine their search based on criteria like location, property type, price range, and amenities.

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.
