About Kishan Singh

AboutI’m a Software Engineer with a strong foundation in full-stack development and a deep passion for designing and building scalable, distributed, and production-grade systems. My expertise lies in architecting high-performance web applications, leveraging modern technologies and cloud-native patterns to deliver seamless, real-time experiences at scale.I specialize in developing low-latency distributed systems using technologies like WebSockets, Cloudflare Durable Objects, WebRTC, tRPC, and gRPC, enabling efficient client–server communication and resilient edge-deployed infrastructures. My backend expertise spans Node.js, Express, TypeScript, and Java, complemented by a strong understanding of system design, microservices, and JWT-based authentication mechanisms for secure, stateless communication.As an active open-source contributor, I’ve made notable contributions to LangChain and LangGraph, focusing on improving developer tooling, AI-driven application pipelines, and scalable orchestration of LLM-based systems. I’m passionate about enhancing developer productivity through clean abstractions and composable architectures.My core programming language is Java, which I also use for competitive programming and algorithmic problem-solving. With 400+ problems solved on LeetCode across data structures, algorithms, and system design patterns, I maintain a strong grip on computational thinking and performance optimization.I take pride in writing clean, maintainable, and well-architected code — always with a focus on scalability, reliability, and developer ergonomics. Whether it’s building real-time collaborative systems, optimizing API performance, or deploying globally distributed workloads on Cloudflare’s edge network, I strive to deliver solutions that are both technically sound and elegantly designed.
