Engineering Capabilities
What I Deliver in Firebase & Cloud Architecture
Declarative Security Rules
Bulletproof Firestore and Storage security rules with strict authorization checks, role-based access control (RBAC), and schema validation.
Serverless Cloud Functions
Event-driven TypeScript Cloud Functions for transactional payments (Stripe/RevenueCat), webhook processing, and email/SMS triggers.
Multi-Provider Auth & RBAC
Seamless authentication supporting Google, Apple Sign-In, Email/Password, Phone OTP, and custom JWT session management.
Push Notifications (FCM)
Targeted push notifications, background message handling, deep-link routing, and automated notification lifecycle triggers.
Methodology

Frequently Asked Questions
Questions About Firebase & Cloud Architecture
Why are Firestore Security Rules so important in Flutter?
Without robust security rules, any malicious user can read, modify, or delete your entire database by inspecting client mobile network traffic. Declarative rules enforce server-side validation, ensuring only authenticated users with valid permissions can access their data.
Does Firebase support offline mode in Flutter apps?
Yes. Firestore provides automatic local caching. Users can read, write, and query data with zero network latency, and changes automatically synchronize with the cloud once internet connectivity is restored.
How do you handle Stripe or in-app payments with Firebase?
Payment processing happens securely inside Firebase Cloud Functions. We use webhooks to listen for completed checkout sessions, verify signatures, and atomically update user subscription tiers in Firestore.
