Continuous development and maintenance for one of the largest banks in Belgium. I took care of the planning and development of various components on the site, from building blocks for content editors to complex tools and calculators for loans and credit cards.

Catapult CX

A presentational website for a digital agency, which decided to refresh its website with a new design, but more importantly, allow its content managers an intuitive editing experience with plenty of flexibility to build versatile components to provide a unique UI/UX experience for the user.


A Drupal website for appliances from the Monogram brand. I was responsible for the back and front-end development of several features on the website, such as product listings, search pages, and product detail pages, to name a few.

We also utilized Drupal Migration API to provide continuous content integration into the new site from outside sources supplied by the client.

Training and CPD Platform for the Royal College of Obstetricians and Gynaecologists

Learning, tracking, and evaluation platforms for trainees and doctors from the Royal College of Obstetricians and Gynaecologists. I developed two different platforms with two different purposes for the doctors in the program. The tool enabled them to track their education items which their supervisors could review. Trainees gained points toward their annual training plan.


A marketing website to showcase the client's product offering and ability to connect with potential customers. The goal was to provide a simple and efficient content management experience with the Drupal CMS, as well as implement the provided designs for a pleasant and fluid user experience with eye-catching animations and a simple and effective user interface for easy navigation.


I was responsible for developing several elements in the content editors' workflow in the back-end—providing a good UI/UX for the user and, at the same time, converting those elements into interactable components on the front-end of the website.

Global Media Centre

A platform for content publishers to upload content, process, and present information about it. Clients can log in, view the published material, and also view coverage report data for the selected content.

The platform integrates with Brightcove (a video processing service), AWS for storage handling, and Drupal 8 which handles all of the components, including data manipulation for presenting it in the coverage report.

I was the lead developer on the team. I was responsible for the said components, integration with third-party services, and custom development work for the coverage reports.


An online insurance policy wizard for customers and a custom-built dashboard for agents to help them manage policies, rates, clients, and various other settings of the platform.

I was the lead developer on the project, responsible for the main platform architecture, the backend dashboard for agents to view various information, and also the frontend policy wizard which is used by the customers to buy their insurance policy. I was working on both the functionality of the features as well as the look and feel of them.

Home at Home

A commerce site migrated from WordPress with several custom commerce and business logic implemented for the editors to use such as discounts, vouchers, CRM integration, page displays, and more.

My role as the team lead was to coordinate the team with tasks, being responsible for the overall site architecture, development and deployment processes as well as communicating with the client and the team on various code implementations.


An educational platform for students all around the world that wish to study in Australia. The platform unites students and agents and gives them both a tool to communicate and work with courses and universities in Australia. Students can compare different courses, universities and also apply to them. The agents take care of everything needed for the student to come to Australia and study.

In a team of three—myself, another developer, and a designer—I acted as the lead developer, coordinating the team with the client on the development and on the design phase. I was responsible for the platform's architecture, development plan, and various components inside the platform.


An educational platform where students can purchase and view various educational videos through subscription. It is also a platform for the video providers who can submit their videos for purchase, view purchases, and income for each video.

I was one of the developers on the team, I was responsible for the submission workflow and dashboard of the video providers on both the development and UX aspect.
