My Projects
Here are some of my recent projects that showcase my skills and experience
BrowseAble – AI Accessibility Chrome Extension
Developed a Chrome extension using React and Gemini API to adapt web pages for neurodivergent users (ADHD, Autism, SPD). Implemented user-role authentication and integrated Firebase for personalized accessibility. Enabled summarization, font adjustments, and dynamic DOM overlays.
Distributed and Hybrid Query Engine for DuckDB
Built an extension for DuckDB to support distributed and hybrid query execution across multiple nodes. Designed a framework for data partitioning and adaptive query planning based on hardware variability and network conditions.
Badminton Shot Classification using ML
Classified badminton shots using OpenPose-based skeleton keypoints from videos. Engineered joint angles and shot trajectory features. Trained Random Forest, SVM, and LSTM models achieving 87% accuracy. Enabled athlete feedback in real-time.
AllBank – AI-Driven Inclusive Banking Solution
Developed a holistic React Native and Firebase-based app integrating QR payments, goal-based savings, and Gemini-powered conversational AI to support financial literacy and decision-making for underbanked communities.
DevC 2.0 – AI Food Ordering Hackathon App
