At Kalpla, I build real-time learning infrastructure spanning a Next.js 15 and React 19 frontend, a NestJS backend, and a custom mediasoup WebRTC media server. I delivered live classrooms with sub-500ms media latency, Socket.IO signaling, and live attendance tracking.
I engineered a server-side recording pipeline using Playwright, MediaRecorder, S3 multipart uploads, and CloudFront signed URLs for secure session playback. I also contribute to a 34-module backend with roughly 490 versioned REST endpoints and 91 Prisma models.
I build event-driven payment, wallet, and payout systems with Razorpay and Bull queues, while maintaining Turborepo monorepo infrastructure, shared API contracts, Dockerized PostgreSQL, and Redis. My work emphasizes end-to-end type safety and scalable delivery.
Previously at Zysk Technologies, I delivered production web and mobile applications across booking, e-commerce, and HRMS. I improved application performance by 40%, reduced redundant API calls by 45%, and shipped cross-platform mobile apps supporting more than 1,000 users.
