About Me

Hello! I'm Simon Stijnen, a software Engineering & AI student at VIVES University of Applied Sciences. I build software that works, scales, and is maintainable; even under heavy load.

My Background

With over 5 years of experience in software development, I focus on creating responsive, accessible, and high-performance applications. I have worked with a variety of clients, from startups to established organizations, to help them achieve their digital goals.

I learn fast and apply new technology in practice. At 17, I built a system to determine device locations using Bluetooth signal strength, similar to how satellites operate. Today, I work with AI and developed Pop-a-loon, a browser extension with over 200 active users.

In 2023, Rotary International recognized me as the top graduating student in secondary school; a recognition of my dedication, curiosity, and results.

When I'm not coding, you'll find me on the ice. I've been playing hockey for 7 years with Brugsche Beiren, and there's something about the fast pace and split-second decisions that keeps me coming back. Plus, debugging code after a good game always feels easier somehow.
