Post-it! - HackTCNJ 2025

Returning back to HackTCNJ 2025 for my third year, my goal was to create a project that would introduce me to new technologies and tools that would also be fun to use and interact with. This led to the development of Post-It!— a full-stack web application which features a collaborative bulletin board to enhance student productivity, where users can share ideas via sticky notes and images!

To ensure secure access for this application, we implemented OAuth authentication, allowing students to sign in via SSO. MongoDB serves as our database, providing a scalable and flexible solution for storing notes, images, and user interactions efficiently. Our tech stack includes Node.js for the backend, ensuring seamless API handling, and React for the frontend, delivering a responsive and intuitive user experience.

Additionally, we integrated GPT-powered AI to help students summarize discussions, generate topic suggestions, and enhance collaboration by providing intelligent insights. This combination of technologies creates a modern, real-time, and engaging platform for students to collaborate effectively.

Our project was awarded first in the category: Most Creative Hack, and you can view our DevPost below.
