AI Doctor is an advanced medical chatbot powered by a Retrieval-Augmented Generation (RAG) system. Leveraging LangChain, OpenAI API, and embeddings, it retrieves relevant medical information and provides accurate, context-aware responses. With a user-friendly Streamlit interface, AI Doctor offers instant, intelligent support for health-related queries.

Database QA Tool

GEN_AI_Database_QA_Tool

AI-powered question-answering tool designed to interact with relational databases using natural language queries. Built with LangChain, the tool leverages machine learning techniques and prompt engineering to translate user questions into syntactically correct SQL queries, execute them, and return accurate answers.

BERT Twitter Sentiment

BERT-Driven-Twitter(X)-Sentiment-Classifier

Twitter (X) sentiment analysis tool using a fine-tuned BERT model. Built with Python, it leverages Hugging Face Transformers for prediction and Streamlit for an interactive UI. Users can input text to get real-time "Positive" or "Negative" sentiment predictions with confidence scores.

Log Classification System

Gen AI-Powered Log Classification with Regex, Clustering, and Regression

Hybrid Log Classification System designed to intelligently analyze and classify system logs. The system integrates LLM, Regex-based preprocessing, Sentence Transformers, DBSCAN clustering, and Logistic Regression into a unified pipeline.

Agentic E-commerce

Agentic AI-Based E-commerce Price Tracker and Smart Buyer

An Agentic AI system that acts as a smart e-commerce assistant, interpreting user-defined purchase rules through natural language and autonomously evaluating conditions to simulate buying actions. It uses OpenAI's LLM for rule extraction, Selenium for live data scraping, and Streamlit for the UI.

React Movie Searcher

React_Based_Movie Searcher_App

A frontend web app built with React that lets users search for movies and save favorites. It integrates a public movie API, uses Context API for state management, and features a responsive UI with a favorites page for a personalized experience.

News Articles QA Tool

NEWS_Articles_Q&A_Tool_With_Langchain

This project is a Generative AI (GenAI) tool designed for automated question answering on news articles. It uses NLP techniques with LangChain and OpenAI API to extract and generate contextually accurate answers. The UI is built using Streamlit, enabling users to input articles and ask questions.

House Price Prediction

house price prediction using machine learning

I developed a machine learning model to predict house prices based on various features such as location, size, and amenities. The end-to-end solution includes data preprocessing, feature engineering, model training, and evaluation using algorithms like Linear Regression, Random Forest, and XGBoost.
