Backend Complete – Ready for Integration(Day-19)

 

Backend Wrapped – A Solid Milestone Achieved!

Today was a fulfilling day — I finally completed the backend for the Codeforces Tracker project! From basic CRUD to smart features like contest history, submission analysis, cron job setup, and reminder logic, the system is now ready to serve dynamic data to the frontend.

What I Finalized Today:

  • Finalized All API Endpoints

    • Student list, creation, update, delete

    • Codeforces handle-based submission and contest history fetch

    • Toggle reminder emails

  • Data Flow Tested

    • Verified all major routes with mock data using Postman

    • Checked edge cases and fallback mechanisms

    • Ensured proper status codes, JSON structure, and error handling

  • Cron Job Logic

    • Synced data automatically with a daily schedule

    • Enabled last sync time display for each student

  • Reminder Email Logic

    • Integrated placeholder function for email alerts

    • Built toggle switch to enable/disable for individual users

 Key Learnings:

  • Writing scalable APIs means planning ahead — every decision on naming, structure, and response format affects frontend usability

  • Cron jobs are powerful for background automation when used carefully

 Gracias:

Super grateful for reaching this phase! 
 I’m excited to move to frontend integration and start visualizing all this meaningful data!

Revising GitHub CLI commands (Day1)

GitHub CLI Revision Today I marked the beginning of my revision journey, and I started with GitHub CLI.  I revised all the commands using GitHub Docs and Git Cheat Sheet.
