Message

At KNP Technologies Pvt Ltd, I optimized Node.js and MongoDB backend workloads, reducing a query’s latency from 700 ms to 100 ms. I also built an IMAP email-ingestion pipeline and managed AWS EC2 and S3 deployments.

I’m now focused on systems programming in C++17. I designed and implemented a cross-platform asynchronous TCP server with Windows IOCP and Linux epoll backends, shared message processing, and session-aware routing.

I also built Snatch DL, a Windows terminal download manager that coordinates jobs through background workers and invokes yt-dlp. Both projects are in development.
