Experience

Mohali · Event-driven backends, real-time Telegram Mini Apps, Redis-backed APIs, and multi-chain staking and rewards.

• Architected an event-driven backend using BullMQ queues and workers with Redis, reducing a critical data-processing pipeline from ~4 seconds to under 100 ms — a 40× throughput improvement.
• Built real-time communication systems with Socket.IO featuring dynamic room creation and event-based state synchronisation, enabling live multi-user interactions across Telegram Mini Apps.
• Implemented Redis caching layers for hot-path API routes and session data, cutting average response times by 60% under peak load.
• Launched Telegram Mini Apps using React, Node.js, and TON Connect enabling wallet authentication, referral systems, and gamified user engagement.
• Authored staking smart contracts using Solidity and deployed backend reward distribution services across TON, Binance Smart Chain, and Solana networks.

Mohali · Scalable REST APIs, Next.js SSR, and WebSocket services across multiple production products.

• Designed scalable REST APIs in Node.js and Express with role-based authentication, secure authorization flows, and structured error handling across 3 production products.
• Established real-time communication systems using WebSockets and Socket.IO, enabling live data synchronisation and event-driven updates across client applications.
• Built server-side rendered applications using Next.js, improving SEO indexing and reducing client-side rendering load.
• Delivered REST APIs and Socket.IO services for the Jodo-Cabs Flutter application, reducing response latency by 40%.
