Raj Kantaria
Hi there! I’m Raj, a developer with a passion for building things that live on the internet. I created this blog as my personal 'digital garden'—a space where I document my learning journey, share technical deep-dives, and keep notes on the projects I’m tinkering with. I’m a firm believer that the best way to master a concept is to explain it to someone else, so I hope you find something here that helps you on your own path.
