About Me

Hey! I'm an AI/ML Engineer who loves turning research into real products. I work with 🔥 PyTorch and Scikit-Learn to build and train models, and I'm deep into LangChain & RAG pipelines for production-grade AI agents.

On the backend I ship fast, scalable APIs with ⚡ FastAPI backed by PostgreSQL and Redis, deployed on ☁️ AWS via Docker. I write clean Python and C++, wrangle data with NumPy & Pandas, and I ❤️ GPUs.
