A Java-based college enrollment system with a Hogwarts-themed Swing desktop interface and a socket-driven client/server backend. It supports student registration and login, course catalog browsing, enroll and drop workflows, admin course management, balance handling, and report logging with file-based persistence.

I design and develop full-stack tools that help teams collect better data, streamline operations, and manage sensitive workflows with more confidence.
Featured work worth exploring
Selected projects that show how I approach real workflows, from registration and payment systems to admin tools, reporting, and database-backed applications.
A full-stack event registration system that lets car show participants, vendors, and sponsors submit tailored forms and complete payment through a server-backed checkout flow. The React frontend validates each registration path, while the FastAPI backend creates and captures PayPal orders, verifies payment webhooks, and stores customer, order, vendor, sponsor, car, and payment records in Supabase.
Practical systems for small teams
I help turn manual workflows into clearer, more reliable software, from structured intake forms and payment records to admin tools, reporting, and safer handling of operational data.
