Projects
Real-Time Sign Language Alphabet Recognition using Computer Vision
- Developed a real-time sign language alphabet recognition system using MediaPipe for hand landmark extraction and TensorFlow/Keras for alphabet classification from webcam input.
- Integrated text-to-speech functionality to convert predicted alphabets into spoken output, enabling users to construct words interactively.
Multimodal RAG System for Intelligent Document Question Answering
- Designed and developed a Multimodal Retrieval-Augmented Generation (RAG) system for intelligent document question answering from text PDFs,scanned PDFs,DOC files,OCR-based documents,and images, implementing an end-to-end pipeline for text extraction,OCR,image captioning,chunking, embedding generation,and semantic retrieval
- Built a scalable FastAPI backend integrating BGE Embeddings, PaddleOCR, Vision-Language Models, PostgreSQL (pgvector), Full-Text Search, and REST APIs to enable hybrid semantic search and multimodal document understanding.
Customer Segmentation using Machine Learning
- Developed a Machine Learning customer segmentation model using K-Means Clustering to identify customer groups based on purchasing behavior, performing data preprocessing,feature engineering, feature scaling, and Exploratory Data Analysis (EDA) to improve clustering quality.
- Evaluated clustering performance using the Elbow Method and created data visualizations with Matplotlib and Seaborn to derive actionable business insights for data-driven decision-making.
