Full Stack Engineer & CS Student @ MSIT
Hi, I'm Kunal Kumar, a Full Stack Engineer and Computer Science and Engineering student at Maharaja Surajmal Institute of Technology (MSIT) from New Delhi, India.
I engineer high-performance web applications, leveraging modern stacks including Next.js, Node.js, and Socket.io. I focus on developing clean interfaces, optimizing backend flows, and creating digital Access Points that streamline professional connections.
Languages, frameworks, databases, and developer tools I build with.
A selection of tools and applications I've built.
A digital access point link-in-bio tool enabling users to unify their professional identities. Features a high-performance URL shortener, a dynamic drag-and-drop interface for real-time link management, and a physical-to-digital bridge via unique QR codes.
A specialized sugar monitoring web application designed for real-time health tracking. Integrates MongoDB Aggregate Pipelines to compute metrics, and features automated glucose tracking mechanisms to streamline health monitoring for Type 1 Diabetes users.
Deep dives on backend systems, architecture, and technology.
A technical deep dive into how DapLink is architected to combine link-in-bio directory hosting, URL shortening, real-time community chat, and high-performance click-through-rate analytics.
A practical overview of managing WebSocket handshakes, JWT authorization on connections, and scaling message streams with Socket.io adapters.
