Feature Inventory: Real-Time Mobility Platform

Overview of Core Features

• F1: Real-Time Geospatial Driver-Rider Dispatch & Matching: Live WebSocket telemetry streaming driver GPS coordinates and broadcasting ride dispatch requests within geographic radiuses.
• F2: Dynamic Fare Matrix, Routing & Google Maps Polyline Rendering: Computes mileage, durations, and multi-tier pricing (Car, Moto, Auto) via Google Maps Distance Matrix.
• F3: End-to-End Cryptographic Ride Lifecycle & OTP Handshake: Secure 4-digit numeric OTP generation, start-ride verification handshake, and transactional state progression.
• F4: Dual Persona Identity & Token Blacklisting: Isolated rider and captain portals, salted bcrypt hashing, JWT issuance, and TTL-expiring token revocation on logout.
• F5: Kinetic Mobile-First UI & Bottom Sheet Drawer Choreography: GSAP-driven sliding panels, interactive vehicle selection drawers, and autocomplete suggestions.

Say It Out Loud (Feature Summary)

"When explaining this system to an interviewer, I emphasize how the platform bridges asynchronous HTTP REST APIs with low-latency WebSockets. The entire ride journey—from initial fare estimation and radar driver search to the cryptographic OTP start verification and live route tracking—operates as a deterministic distributed state machine designed to eliminate race conditions and keep both parties perfectly synchronized."
