about me

I was born in Brussels and lived there most of my life before moving to the UK, where I first discovered the world of computer science during a preparatory program. What started as an interest in problem-solving quickly grew into something deeper: a desire to understand how technology can shape experiences and impact people's lives.

During my studies at , I joined , a student team developing an exoskeleton for people with spinal cord injuries. I wanted to apply the theoretical knowledge I was learning to something concrete and hands-on, and the strong human focus of the project really resonated with me. That experience was a turning point, it's where I realized I loved working at the intersection of technology and the user, and where my interest in interfaces and front-end development truly took shape.

Since then, I've continued along this path at , where I've had the chance to work with incredibly talented people and inspiring clients. There, I've been able to deepen my technical skills while contributing to polished, robust, and accessible platforms. Alongside building, I also enjoy teaching and mentoring, whether as a teaching assistant or through collaboration, and I find a lot of joy in helping others learn and grow.

Today, I'm drawn to projects that are thoughtful, human-centered, and made with care, where technology doesn't just work, but feels good to use!

And when I'm not coding, you'll probably find me having coffee and pastries with friends, behind my camera lens, or reading a good book.
