I'm a Senior Node.js Engineer with 4+ years of production experience. At Solvebyte, I currently maintain the backend of a live iGaming platform serving 1M+ active users — handling production incidents, resolving crashes, and ensuring 99.9% uptime across wallet operations, betting flows, and game APIs. I've also reduced API response times by ~30% through PostgreSQL and MongoDB query optimisation on the same stack. Previously at GammaStack, I built and maintained full-stack iGaming and sportsbook products — integrating PayPal, RazorPay, CCPayment, and NowPayment gateways, streaming real-time sportsbook odds via WebSocket and RabbitMQ, and mentoring a 10+ person engineering team. My core stack aligns directly with this role: Node.js, TypeScript, PostgreSQL, MongoDB, Redis, REST APIs, WebSockets, Docker, and AWS. I have working knowledge of NestJS and use it in my current project. I'm based in Indore, open to remote work as well as relocating to Tier 1 cities (Bangalore, Hyderabad, Pune, Mumbai), and available for hybrid or fully remote arrangements.
