Maria Parveen

I’m a junior AI/ML engineer focused on production-ready LLM-powered systems, especially RAG and NLP. I built and deployed a secure PDF RAG Assistant with authentication and per-user chat history, using Streamlit, ChromaDB, and the OpenAI API.

I enjoy taking models from data to measurable results. I’ve built and evaluated supervised ML models using train-test split, feature engineering, and metrics like accuracy, precision, recall, and F1-score, and I use SQL-based data extraction to support pipelines such as churn/business prediction.

Alongside my AI/ML work, I combine freelance web development and data analysis experience to ship end-to-end products. I’m hands-on with Transformers, embeddings, semantic search, prompt engineering, and deployment/debugging—so I can deliver reliable systems and keep improving them.
