Full Stack & Custom Firestore Engine

Core Engine

Offline-first real-time synchronization, mobile caching & end-to-end cloud backends.

Custom Firestore Sync & Caching Engine

Proprietary Mobile Caching Layer & Read Quota Optimization

Proprietary offline-first synchronization and caching layer engineered over Firebase Firestore. Eliminates listener memory leaks, provides sub-15ms cache read responses, and cuts document read billing expenses by up to 70%.

1. Optimistic Local Queue

Mutations apply to the UI in 0ms. Transactions are buffered locally in SQLite/MMKV and sequentialized with exponential backoff on reconnect.

2. Smart Delta-Listeners

Replaces heavy collection queries with timestamped delta queries, preventing listener spikes during app background/foreground transitions.

3. Automated Conflict Merge

Three-way merge algorithm with optimistic rollback, ensuring offline device edits never silently overwrite fresher cloud snapshots.

Full Stack Client-to-Cloud Tiers

Native iOS (Swift/SwiftUI) + React Native Expo frontend apps connected with Node.js Cloud Functions, Python FastAPI inference endpoints, and Cloudflare Pages/Workers edge distribution with sub-50ms global latency.

Fintech Reliability (Zeta Directi)

Engineered offline-first banking transactions, biometric cryptographic authentication (FaceID / TouchID / Android Keystore), and 99.95%+ crash-free session rates across millions of enterprise users.
