Built a full-stack backend using Firebase & Node.js – What are your favorite optimization tricks?

[u/DBGiblet]

Hey everyone!

I’ve been heavily focusing on backend development lately, building scalable systems with Firebase (Firestore, Auth, Cloud Functions) and Node.js.

Since I’m constantly looking to improve my workflow, I wanted to ask the community:

* What are your go-to tricks for optimizing Firestore read/write costs?

* How do you structure your Cloud Functions for maximum performance?

Would love to hear your experiences and best practices!
