Hi folks, recently I have created a small web application where we can find the link of the specific problems from recent past contests. You can add filters according to the contest type and problem number along with the user id and categories it into solved, unsolved and hold problems, once you first fetch the data, it will be stored locally. Username, contest type, and problem number should be filled for the application to load the problems. I am still working on this so there might me some scope for improvement.

Hope you will like it. GitHub Repo: https://github.com/sanjay-1458/Codeforces-Recent-Problem-List

Edit: The live link fetch only 5 problems for now, and you can set the number of problems in the JavaScript file. The time taking for the problems to display on the UI depends upon the number of problems and currently it takes almost 2 minutes for 10 problems. The current issue which you may face is you have to set the number of problems from JavaScript file and the wait time between fetching and displaying the problems.
