- Built a full-stack ride-booking platform with a decoupled monorepo architecture — Next.js 14 App Router paired with a standalone Socket.IO server — supporting 3 roles (Passenger, Driver, Admin) across 8 RESTful API domains. – Integrated Socket.IO for real-time driver location streaming, in-ride chat, and targeted ride-dispatch broadcasts with a server-side /emit proxy for server-to-client pushes. – Implemented a double-OTP ride verification system, Razorpay payment integration, and an 8-step driver onboarding pipeline covering document uploads, vehicle registration, and live Video KYC via ZegoCloud.
