My Projects

Intelligent RAG Chatbot with Appointment Booking

Built a conversational AI assistant using LangChain and Retrieval-Augmented Generation for document-aware Q&A. Developed a FastAPI backend for query handling, embedding generation, and caching, with a Streamlit interface for interaction. Used Chroma vector database for semantic search and Redis caching to reduce redundant LLM calls, improving response speed and lowering costs.

KAWACH – Real-Time Malicious URL Detection

Built a Chrome extension powered by an LSTM model to classify and block malicious URLs in real time. The system analyzes lexical patterns to detect phishing and harmful links, intercepts user navigation, and prevents access to flagged websites.

Face Matching with Siamese Network

Built a Siamese CNN model for face verification by comparing image pairs and predicting similarity scores. Trained on a custom dataset with contrastive loss and data augmentation, achieving reliable accuracy despite limited samples, and developed an evaluation pipeline for robust performance assessment.
