09 / 14Tech Architecture · World-class infrastructure, already shipped

The platform competitors take 3 years and ₹100 Cr to build — we already have.

Cloud-native, event-driven, multi-region ready. Hungarian-algorithm dispatch on Fargate. Real-time tracking via AppSync. ConnectRPC gateway. Single-table DynamoDB. 47 CDK stacks. Built solo, audited for security and compliance.

12-factor matching algorithm

Hungarian assignment optimizing for ETA, driver fairness, surge, vehicle fit, ride pooling, rider preference, dashcam status, language match, last-trip rest, fuel type, traffic, and historical reliability. Outperforms broadcast-first dispatch by 23% in pickup latency on synthetic load tests.

Single-table DynamoDB

11 access patterns served from 1 table with 4 GSIs. Sub-15ms p99 reads at any scale. No JOINs, no schema migrations, infinite horizontal scale.

47 CDK stacks · IaC

Every resource in code. Disposable environments. Dev/staging/prod parity. Compliance-ready audit trail of every infra change.

Real-time at planet scale

AppSync GraphQL subscriptions deliver driver location, ride state, and SOS broadcasts in <300ms p99. WebSocket presence channel for chat. Kinesis event journal for replayability.

Hardware-software loop

Dashcam device pairs over BLE, streams to S3 over Wi-Fi/4G with on-device buffer. ML pipeline (Rekognition + custom) flags incidents in real-time. End-to-end encrypted in transit + at rest.

56-finding security audit · all critical fixed

Internal audit Apr 2026: HMAC signing on all webhooks, audit logging on every privileged action, IAM least-privilege across 47 stacks, DPDPA-compliant consent flow.
