About

I possess a strong knowledge of CS fundamentals such as Data Structures and Algorithms, Object-Oriented Programming, Database Management Systems, Operating Systems, and Computer Networks. Gained an in-depth understanding of the Unix environment and the Version Control System via internships and open-source contributions. I have also built projects using Deep Learning and worked on full-stack technologies. Recently, I have used LLMs in production applications, integrating them with backend services, vector databases, and retrieval pipelines to deliver scalable AI-powered capabilities.
