Manas Kalangan
Hello! I am a Master's student in Computer Science and Engineering at the University at Buffalo with a strong foundation in backend engineering and systems thinking. With ~3 years of professional experience as a .NET developer, I have built and shipped production-grade software ranging from REST APIs and desktop applications to distributed systems components. See my open-source contributions.
I enjoy working close to the fundamentals like databases, system design, and performance, while also exploring applied AI through explainable retrieval systems, RAG pipelines, and multimodal projects.
