Welcome to my website
This is where I share projects I've built, from interactive dashboards to small programs. The website grows with every new project.
About me
I'm Simon, and I use this site to share my projects. I'm interested in physics, data analysis and technology in general. Economics and finance fascinate me most. I use tools, projects and dashboards of my own to understand these subjects and share what I learn.
C and C++ were my first programming languages, and I used them to build small games. When I wanted to publish those projects on the web, I learned HTML, CSS and a little JavaScript and built this site. It grows with every new project.
I analyse data and build my own tools to understand how things connect and make complicated topics easier for myself and others to follow.
