Projects
COSC 4353 Volunteer Management System
Summer 2025
The Problem
For a software engineering course, the challenge was to build a comprehensive volunteer management system from scratch with a team. The system needed to handle complex volunteer coordination, event management, and real-time updates while demonstrating full-stack development and deployment skills.
The Solution
I led the development of the admin dashboard and backend architecture for a complete volunteer management system. The React frontend with Vite provides a responsive interface for volunteer coordination and event management. The Node.js/Express backend, deployed on Vercel, handles volunteer assignments, skill matching, and real-time calendar updates. Key features include an admin dashboard with comprehensive reporting, drag-and-drop event scheduling, skill-based volunteer matching, and live synchronization across the platform.
MusicBot
Sept 2024 – Present
The Problem
Music playback in Discord servers often relies on cumbersome text commands and offers limited user convenience.
The Solution
I developed a Python-based Discord bot using discord.py and youtube_dl. A key feature is dual interaction support — traditional text commands and interactive buttons — to accommodate users of all experience levels. Asynchronous processing enables the bot to handle concurrent requests with no perceptible latency.
COVID-19 Chest X-ray Detection
Spring 2025
The Problem
Rapid triage of COVID-19 from chest X-rays is high-volume and time-sensitive. Clinicians need automated assistance to flag likely pneumonia cases quickly.
The Solution
Built a transfer-learning classifier with EfficientNetV2-B0 in TensorFlow/Keras on the CoronaHack Chest X-ray dataset. Two-phase training (frozen base → fine-tuning), class weighting, and targeted augmentation improved generalization. Final model reached 89.10% test accuracy, 0.9643 AUC, and 97.7% sensitivity for pneumonia.
Museum Management System
Fall 2024
The Problem
For a capstone database course, the brief called for a practical full-stack application demonstrating database design, API development, and front-end integration. The challenge was to deliver a comprehensive system from scratch within a single semester.
The Solution
I designed and developed a complete museum management system. The back-end, built with Node.js and Express, exposes a robust RESTful API for all CRUD operations against a MySQL database. The React front-end consumes this API to provide an intuitive interface for managing exhibits, staff, and visitors. The entire application is deployed on Azure Static Web Apps for reliable and scalable hosting.
