I'm a Data Scientist with 5+ years of experience, mostly in e-commerce and retail. I enjoy building ML models that actually go to production and make a measurable difference. Lately I've been focusing on LLMs, RAG systems and agentic workflows — that's the direction I'm growing toward.

Machine Learning XGBoost LightGBM Scikit-learn PyTorch

LLM & GenAI LangChain FAISS Gemini API RAG Function Calling Agentic Workflows

Cloud & MLOps GCP Vertex AI BigQuery MLflow

Data & Scripting Python SQL Pandas NumPy

Retrieval-Augmented Generation system built on 568K+ Amazon reviews. Users can ask questions about products and get grounded, context-aware answers.

LangChain FAISS Gemini Streamlit (in progress)

XGBoost/LightGBM model predicting campaign response likelihood for retail customers. Delivered 12% uplift in conversion rates in pilot campaigns.
