About Me ๐Ÿ‘จ๐Ÿปโ€๐Ÿ’ป

been where? done what?

Nice to meet you! My name is Khalid, and I have been working as a web developer for the last 10+ years.

Passionate about programming since the spread of computer and networking systems. Confident about the knowledge of bytes and how they are created, processed, mesmerized, and networked. I have worked on projects ranging from small company and personal websites to full fledged web applications and mobile app integration with cloud systems serving millions of users without a single minute of failure.

I deeply enjoy building complex things that require simplification and knowledge with, especially if it's something that is useful or nice ...or both!
