About
I’m Sumit Mishra, a full stack developer who enjoys building reliable products end-to-end—from backend workflows and REST APIs to responsive user interfaces. I’ve worked on large-scale, real-world systems for the Indian Railways, where I focused on improving fare-rule processing, ticketing logic, and passenger-facing stability through careful testing and defect resolution.
I also enjoy creating AI-powered applications. In my projects, I’ve led development of an AI security assistant using LLM tooling and secure authentication, and I’ve built chatbot experiences with fast, context-aware response handling. I like collaborating across teams (Android, QA, DevOps, and domain experts), documenting workflows clearly, and continuously improving performance, maintainability, and quality.
