Contributing to Zed's open source taught this dev more than just how to write extensions. From Tree-sitter parsing to WASM sandboxing, find out what shipping real tools to real users actually looks like.

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.

Just 2 early-bird tickets remaining—snag yours now! 🙌
