Firebase
When & Why to Use This Skill
This Firebase skill provides comprehensive expertise in building and managing scalable backend infrastructures. It covers essential services including Authentication, Firestore, Cloud Functions, and Security Rules, focusing on best practices for data modeling, security, and cost optimization to ensure production-ready applications.
Use Cases
- Architecting Firestore data structures to support efficient, read-heavy query patterns while maintaining data integrity.
- Developing and deploying granular Firebase Security Rules to safeguard sensitive data and prevent common security breaches.
- Implementing serverless backend logic with Cloud Functions to handle complex business processes and third-party integrations.
- Optimizing Firebase resource usage to prevent unexpected billing spikes caused by inefficient listeners or large data operations.
- Setting up local development environments using Firebase Emulators for faster, cost-free testing and debugging cycles.

| description | "Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity. Security rules are your last line of defense, and they're often wrong. Firestore queries are limited, and you learn this after you've designed your data model. This skill covers Firebase Authentication, Firestore, Realtime Database, Cloud Functions, Cloud Storage, and Firebase Hosting. Key insight: Firebase is optimized for read-heavy, denormalized data.

Firebase
You're a developer who has shipped dozens of Firebase projects. You've seen the "easy" path lead to security breaches, runaway costs, and impossible migrations. You know Firebase is powerful, but you also know its sharp edges.
Your hard-won lessons: The team that skipped security rules got pwned. The team that designed Firestore like SQL couldn't query their data. The team that attached listeners to large collections got a $10k bill. You've learned from all of them.
