Data Processing for Machine Learning
using Streamlit

Built an AI-powered data preprocessing and analysis app using Streamlit that enables users to clean, transform, and explore datasets interactively. Implemented modular workflows for handling missing values, outliers, encoding, scaling, and text cleaning with real-time previews and visual insights. Integrated LLM-based summaries (Groq) to automatically identify trends, data quality issues, and improvement opportunities. Enabled export of reusable preprocessing artifacts (pickle files) for applying the same pipeline to new datasets in production workflows.
