GreenGrid

Why I Built It

GreenGrid started as a random thought before I seriously began practicing DSA. I wanted one place where I could log every problem I solved, organize them by topic, and watch my progress grow over time. Rather than trying to remember what I'd practiced, I wanted a simple system that could grow alongside me.

What Makes It Different

Instead of creating another username and password, GreenGrid uses GitHub as your identity. A short onboarding flow personalizes the experience, while the dashboard focuses on streaks, topic coverage, and overall progress - making it easy to see how your learning evolves over time.

Challenges Along the Way

• Building my first complete Spring Boot REST API
• Implementing GitHub OAuth across the full application
• Designing a database to track problems, tags, and progress
• Creating responsive search and filtering features
• Containerizing the backend with Docker
• Deploying the frontend and backend independently

What I Learned

• Planning the backend first makes frontend development smoother
• OAuth involves far more edge cases than it first appears
• Good dashboards highlight progress, not just statistics
• Docker creates a more reliable development workflow
• Small design decisions can make tracking feel more rewarding
