(ABOUT ME)

Building AI Systems &
Scalable Solutions

I'm a Computer Science undergraduate at IIT Kharagpur '26, specializing in SDE, Generative AI, and full-stack development. I build practical AI systems including RAG pipelines, multi-agent LLM workflows, NLP models, and production-grade dashboards.

As the Co-Founder & Technical Lead at CampusBuzz, I lead product architecture and engineering for a campus-scale networking and career platform across IITs & NITs. My work spans backend engineering, scalable system design, vector databases, web scraping, and end-to-end GenAI/SDE application development.
