Who Am I

Hola 👋,
I’m Yousef, a Pragmatic Software Engineer obsessed with Javascript, highly focused on the performance of web applications with +2 experience building resilient products on top of NodeJs and Typescript.

I love writing due to the love of knowing and mastering something, I love digging into the internals of anything I am exposed to, so writing helps me have a clear and strong mental model about that thing.

📖My writings are mainly about:

  1. Explaining Backend & Software Engineering Technical concepts.
  2. Best Practices of coding
  3. Internals of Architecture, tools, and languages we use on a daily basis
  4. Software Engineering career guidance and advice.
