I'm Yousef Khaled, but most people online know me as Jax. I'm a medical student and a self-taught developer, building things under the name muxover.

My interest in programming started in 2018, when I got my first PC. A few friends introduced me to the username market, and I remember being fascinated by how a small script could do in seconds what would take a person much longer. I wanted to understand how that was possible, and that curiosity eventually got me into programming.

C# was my first programming language. A few years later, I picked up Go and started exploring more of what I could build with it.

In 2023, I graduated from high school in the UAE and eventually found myself in Egypt, where I chose medicine over computer science. I knew it would be a completely different path, but I wanted to give it a shot.

Medical school ended up taking most of my time, and programming gradually took a back seat. For a while, I stepped away from it to focus on my studies.

Then, in late 2026, after finishing my third year of medical school, I found myself wanting to build again. I came back to programming with a different mindset and a clearer goal: to create something of my own. That's where muxover comes in.

Today, I'm building my own apps and services, exploring ideas, and sharing the things I work on. I'm particularly interested in the networks and infrastructure behind the apps and services people use every day, the things most people never really think about but rely on constantly.

I'm still figuring things out, learning, and building along the way. There's a lot I want to create, and this is where I'll be sharing that journey. Welcome to muxover.
