📚 What We Learned

This project was more than just a technical exercise—it was a mindset shift.

• We mastered Spring Boot’s layered architecture and built secure, scalable APIs.
• We learned to troubleshoot independently, gaining confidence with tools like Maven and IntelliJ.
• We embraced clean code principles: realizing that code that runs isn’t enough—code that’s readable, testable, and maintainable is what truly matters.
• We grew as a team, collaborating in a supportive environment and learning from each other and our mentors.

⚠️ Challenges Faced

• Designing business logic for habit tracking required thoughtful planning.
• Initial setup issues with IntelliJ and Maven were resolved with mentor support.
• We learned to approach technical problems methodically, using documentation and community resources.

🔮 Future Improvements

While this internship round was incredibly rewarding, we’d love to see:

• Continued mentorship and access to curated learning materials.
• More opportunities to work on full-stack or deployment-focused tasks.
