Hi, my name is
Leander.
I build things for the web.
I am a dedicated Front-end Developer based in Zürich with over 5 years of experience in the tech industry. I specialize in building robust, scalable web and mobile applications using React, TypeScript, and Node.js. My goal is to bridge the gap between complex backend logic and intuitive, high-performance user interfaces.
01. About me
My professional journey is a blend of technical expertise and unique life experiences. After serving as a Petty Officer in the Belgian Navy, where I developed my discipline and problem-solving skills in high-pressure environments, I transitioned into the world of software development.
Today, I leverage a full-stack mindset to deliver high-quality solutions, having worked with major organizations such as Brussels Airport, the Belgian government, and Eneco. I am passionate about writing clean, robust code, building fast and responsive user interfaces, bridging backend and frontend development, and staying at the forefront of modern tools and architectures.
