It's been a while since I've been excited to contribute to an open-source project.
I've been wanting to switch from vscode to @zeddotdev for some time now. These two extensions, that I opened a PR for, won't prevent from doing that though. 😅

As a backend programmer, I’ve often been more comfortable behind the scenes—building systems, solving problems, and letting the code speak for itself. But in today’s world, technical skills alone aren’t enough.
We are in a world where reputation and online presence can make or break opportunities.
