Challenges we ran into

The main problem we faced is collecting API's of different platforms. Even though after getting those API access parsing big JSON data is still a problem.Although we somehow able to manage reading and parsing that JSON data but Implementing filter based search was the most though task as it requires a lot of study of JSON data to analyze how we can implement Filter based on JSON data. Implementing Judge0 API for compiler was also somehow difficult as we have to save the code as blob file and upload that file to Judge0 API server after that we will be getting a JSON response containing the Output or Error during the compilation or runtime.
