Backend Progress – Strengthening the System(Day-18)

 

Another Day in Backend – Layering Stability

Today I continued backend development on the Codeforces Tracker project, and spent around 3–4 hours refining, testing, and adding stability to the existing API endpoints. Each improvement helps make the system more scalable and error-proof for future integration.

 What I Focused on Today:

  •  Refined previously built routes for better data consistency

  • Added input validations in the controller methods using basic conditionals

  •  Started basic testing of endpoints using Postman

  •  Added more console/debug logs to trace API flow

  •  Handled possible edge cases for:

    • Empty student data

    • Invalid/missing Codeforces handle

    • Update/delete failure cases

Small Learnings:

  • Realized the importance of status codes — using the right 200, 400, 404, 500 makes debugging and frontend integration easier

  • Naming conventions for route handlers and responses really help with code clarity

  • Added a fallback default cron schedule logic in case no setting is found

 Gracias:

I’m grateful for the chance to work on backend logic in a real-world-style project.
It’s one thing to learn Node.js, and another to build a full system with endpoints, cron jobs, and real-world APIs like Codeforces.

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. Also I revised from GeeksforGeeks also.  Practiced some basic core commands like:  git init, git clone git add, git commit  git push, git pull  git branch, git merge, git checkout Also Created a test repo and tried to pushed the commits using CLI.  I read full explanations from GeeksforGeeks.  Git Workflow -  Also understand how git workflow-> from staging area, working directory.  GitHub also helps in versioning controlling  Challenges -  Sometimes, merge conflicts led to minor confusions like head and current change but exploring little more from Chatgpt and documentation helps in figuring it out.  Gracias- Grateful to have a mentor for guiding me  I'm thankful for this opportunity to revise more and understanding this concept more in a better way ab...

JavaScript Deep Dive + React Review (Day-5)

 JavaScript & React – Interview Prep Mode Today was all about preparing for frontend interviews , and I focused heavily on reviewing core JavaScript and React concepts from the shared 150+ question set. What I Covered: JavaScript Topics: Completed all JS questions from the set Focused particularly on: Promises & Callback functions Closures and how they work under the hood Async/Await and handling asynchronous logic These topics were a bit tricky at times, but revisiting them helped me gain more confidence and clarity. React Topics (Partially Covered): Reviewed around 90 questions Focused on core concepts: useState , useEffect , useMemo Type-related questions and common hook usage I still need to complete the remaining React questions, but the progress so far has been good i learnt more about these topics than i knew before.  What I Learned: Revisited how closures work and why they’re important in functional JS. Understood as...

Starting the GitHub User Search App (Day - 2)

Project Exploration of Github User Search App Today I officially began working on the GitHub User Search App challenge from Frontend Mentor . This marks the beginning of building a real-world frontend project from scratch What I Did Today Explored the challenge brief and UI on Frontend Mentor to understand the overall layout and user flow Carefully observed the design to note color palettes, typography, spacing, and responsive behavior Reviewed and revised important concepts in HTML , CSS , and JavaScript , especially related to: API handling in JS DOM manipulation CSS flex and grid layouts Read documentation and tutorials related to: CSS design techniques for layout structuring JavaScript fetch API to prepare for API integration Set up the basic project structure using HTML and CSS Created the layout for the search box and initial user info card with HTML + styled with CSS What I Learned Importance of design breakdown before starting a proje...
