About

I'm a Computer Science student (2023–2027) specializing in GenAI engineering and backend development. I build production-ready AI applications that bridge modern language models with reliable, deployable systems.

I focus on RAG pipelines, LangGraph agentic systems, and NL-to-SQL workflows, with Django and FastAPI powering scalable APIs and services. My goal is to deliver practical AI that solves real problems and fits into real products.
