Hello, I'm Roel!
I'm a passionate Full-Stack Developer with 8 years of experience crafting scalable and efficient web applications. My expertise spans a range of modern technologies, with a strong focus on React.js, Node.js, Python and AWS.
About me
What excites me most about programming is the problem-solving journey—the thrill of finally cracking a complex challenge never gets old. My core skills include React, Node.js, Python, Typescript and AWS. I am also familiar with Docker, Kubernetes and AWS. I’m always eager to expand my knowledge and explore new technologies. Currently, I’m seeking a full-time position as a Senior Software Engineer.
When I'm not coding, I enjoy playing basketball, watching NBA games, and exploring the art of mind mapping, a technique popularized by Tony Buzan. Mind mapping allows me to visualize ideas, structure complex concepts, and organize thoughts creatively, which helps enhance my problem-solving and planning skills.
