The Problem: Hackathons bring brilliant minds together, but finding the right teammates quickly can be tough. Participants often scramble to form teams, sometimes ending up mismatched or going solo, which affects their overall experience and project success.

The Idea: Having faced this issue myself, I came up with the idea for Hackmate Finder—a command-line tool that helps participants find compatible teammates based on skills and project interests. The goal was to make hackathon team formation smarter and faster.

The Build: Hackmate Finder is built entirely using Java with MySQL for data storage. I used JDBC to connect the application to the database. Users can:

1) Register and log in securely

2) Enter their skills, interests, and preferences

3) Search for teammates using filters

4) Get match suggestions based on compatibility

5) Everything runs through a clean CLI interface, making it lightweight and accessible.

The Impact: This project not only solves a common hackathon pain point but also helped me improve my practical Java, JDBC, and database design skills. It’s a great example of how even simple tools can create real value.

Tech Stack:

1) Java (Core + JDBC)

2) MySQL.
