Nikhil Arora

I’m a Full Stack Developer with 5+ years of experience designing, developing, and deploying scalable web applications. I’m skilled in the MERN stack, backend microservices, API development, and cloud-native deployments, with a strong focus on clean architecture and maintainable code.

In my current freelance role, I built a scalable backend system using Node.js and TypeScript with a modular architecture. I implemented JWT-based authentication and authorization (login, registration, secure route protection), created contract management and KYC modules, and delivered product listing APIs with CRUD support—while enforcing RBAC for secure access control.

Previously as a Sr. Node.js Developer at OneVerseGamingTechnology, I designed and developed microservices for a real-money fantasy and betting platform serving millions of users. I improved service-to-service communication, added caching, and optimized database queries, and I also built an Admin Panel for reporting, tournaments, KYC uploads, role-based login, and bulk registration.

I’ve also delivered real-time and event-driven experiences using Socket.IO and RabbitMQ, including admin-to-client promotional messaging and affiliate workflows (Affiliate → Player, Admin → Affiliate). Earlier roles included building an admin panel with Google Maps and integrating ClearTrip APIs plus payment gateways (Paytm, Razorpay), creating booking APIs for SpiceJet Cabs with IVR/AutoCall confirmations, and developing e-commerce and grocery platforms using React + Node.js and Angular + Node.js.
