Projects
Impact-driven AI/ML systems built end-to-end
AI-SQL Assistant
Writing complex SQL queries is time-consuming and error-prone, especially for non-technical users
Built a GenAI-powered assistant that converts natural language questions into accurate SQL queries using LLMs with schema awareness
Enables instant SQL generation from plain English · Zero SQL knowledge required
Sign Language Detection
Communication barrier between deaf/mute individuals and those unfamiliar with sign language
Built a real-time computer vision system using deep learning to detect and classify sign language gestures from a webcam feed
Real-time gesture recognition · Bridges communication gap with instant translation
Activity Recognition
Identifying human activities from sensor or video data is critical for health monitoring and surveillance
Developed an ML pipeline for classifying human activities using time-series sensor data with feature engineering and ensemble models
High-accuracy activity classification · Applicable to fitness tracking and smart environments
Disorder Divination
Early detection of mental and physical disorders is difficult without clinical tools accessible to the public
Built an ML-based diagnostic system that predicts potential disorders from symptom inputs using classification algorithms
Accessible early-warning tool · Supports proactive health awareness
