UH Marketplace
Live Project: uh-marketplace.github.io
App Demo: uh-marketplace-app.vercel.app
GitHub Org: github.com/uh-marketplace
Overview
UH Marketplace is a secure, UH Mānoa-exclusive platform that allows students and faculty to buy, sell, and trade items like textbooks, electronics, furniture, clothes, and more. Unlike Facebook Marketplace, it’s invite-only with @hawaii.edu authentication for a safer, campus-based experience. Users can post listings, explore categories, message one another, and manage favorites—built with Next.js, PostgreSQL, and Bootstrap 5.
My Contributions
- Developed core pages: Landing, Explore, Profile, Favorites, Messages
- Integrated authentication with UH emails and protected routes
- Set up PostgreSQL and Prisma ORM for the backend
- Wrote E2E tests with Playwright and configured CI/CD on GitHub Actions
- Refined the UI for a clean, mobile-responsive design
- Handled bug fixes, UI tweaks, and improved accessibility

- Build a secure, responsive web app with a modern stack
- Troubleshoot deployment (Vercel), databases, and edge-case bugs
- Collect and apply user feedback to improve UX
