Projects & Publications

Paper Reference System

An academic writing tool designed to streamline literature reviews for researchers and students. The system uses semantic search and natural language processing to summarize academic articles and help users quickly find relevant references, significantly reducing research time.

Tech Stack: Python, ML (semantic search), NLP

Airline Planning System

A flight planning application that uses real Google Flights data to help users create custom itineraries. Features optimized search algorithms built with Pandas and NumPy for efficient flight comparison and route planning.

Tech Stack: Python, Pandas, NumPy

Hearing Disability Assistant

An Arduino-based wearable device designed to assist individuals with hearing disabilities. The system detects critical environmental sounds like alarms, doorbells, and knocks, then logs alerts to a companion web application for real-time notifications.

Tech Stack: Arduino, Web Development, Hardware Integration

Social Media Depression Detection

A research project conducted at Stanford University focusing on human-computer interaction in AI. Built machine learning models using RoBERTa and Decision Trees to detect depression signals in social media content, achieving 82% accuracy. Deployed interactive prototypes using Next.js and Vercel with integrated ML backends.

Tech Stack: Python, RoBERTa, PyTorch, Next.js, Vercel
