THE CLIENT PROBLEM

Peak Hour Concurrency Bottlenecks & High Rider Dispatch Latency

Fynito's initial MVP suffered from frequent GPS sync drops during dinner rush hours, delayed order state transitions between kitchen POS and riders, and abandoned checkouts due to slow payment redirects.

Core Friction Points:

✕GPS location packets from 1,200+ simultaneous delivery riders overloaded the legacy single-node backend.

✕Kitchen preparation status was out of sync with customer order views by up to 45 seconds.

✕Legacy payment gateway failures during lunch/dinner peak hours caused an 38.5% cart abandonment rate.

WHAT WE BUILT & DELIVERED

End-to-End Cross-Platform Mobile Apps, Kitchen POS & Live Telemetry Engine

Divanex redesigned Fynito from the ground up: building custom cross-platform React Native mobile apps for customers and riders, a high-throughput Node.js microservice cluster, and a live kitchen display web portal.

Delivered Architecture Pillars:

Socket.io & Redis Pub/Sub Rider TelemetrySocket.io • Redis • GeoJSON

Streams live rider coordinates with dead-reckoning smoothing, keeping mobile battery consumption minimal while updating customer maps every second.

Distributed Order State MachineNode.js • PostgreSQL Transactions

Deterministic order lifecycle managing placed, accepted, cooking, picked up, and delivered states with idempotency keys preventing double-charges.

Zero-Latency Multi-Gateway SwitchStripe • Razorpay • UPI Deep-Links

Smart fallback between UPI, cards, and digital wallets, achieving 99.7% payment success rate on first attempt.

SYSTEM TOPOLOGY, CODE & SECURITY

Architecture Blueprint & Technology Taxonomy

1. Order Ingestion

Customer Mobile App

Customer places order; signed payload validated via JWT and edge API gateway in <45ms.

2. Kitchen Dispatch

Partner Web Portal

Kitchen POS receives audio chime; kitchen accept updates PostgreSQL state machine instantly.

3. Smart Rider Match

Dispatch Engine

Geospatial proximity query matches nearest idle rider with lowest delivery route ETA.

4. Live HUD Streaming

WebSocket Broker

Rider GPS location broadcasted to customer app with map route interpolation.

Engineering Guardrails & Standards:

Zero dropped orders during 50,000 orders/day peak weekend spikes.

Offline-tolerant rider app with local SQLite caching when entering network dead zones.

Built-in merchant analytics dashboard tracking bestsellers, preparation times, and net revenue.
