I design and build websites and mobile apps that are simple to use, nice to look at and built to last. As a UX/UI designer and developer I guide each project from the first sketch to launch. I start with the people who will use it and stay involved until everything works the way it should.

2About
A bit about me.
Hi, I’m Sayyid. I studied Creative Media and Game Technologies, where design and technology go hand in hand. That combination still defines how I work. I care about how a product looks just as much as how it works.
My biggest project to date is Kinesis+, a booking platform for a personal training and massage studio. Since its launch in September 2026 clients have been booking their sessions through it. Working on it showed me how much close collaboration with a client matters, especially in the final weeks before a launch.
I write code that is clean and easy to maintain so whoever works on it next can find their way around. I’m also always learning. Every project leaves me with something I bring to the next one.
Away from the screen you’ll usually find me in the pool or at the gym. Swimming has been part of my life for a long time. It started in Suriname and I’ve kept at it since moving to the Netherlands in 2021. Training keeps me disciplined and time in the water is my way to switch off for a while. And when I’m not training I’m probably gaming.
