• Back in 2019, I worked as a Senior Software Engineer at Soothsai project MasteryPrep, mainly handling both frontend work and Firebase functions. One of the biggest things I worked on was the quiz creation module in the admin panel. It let admins and moderators build quizzes, and we had about 20 to 30 different types of questions—not just the usual true/false or multiple-choice stuff.
• For example:
• type drag-and-drop : questions where users had to move answers into the right spots.
• type arrangement : questions where they had to arrange options in a specific order.
• type match: there were questions in two columns you have to match column 1 row to column 2 row by draging the connector thingy
• type Image-based questions, which were probably my favorite. I built a heatmap/mask system so users could click on a specific part of an image to answer. It was kinda like a ""Find Waldo"" game—if they clicked the right area, it was correct; if not, it wasn’t.
• A cron job that produced performance reports for students who took quizzes ran daily. The studies helped them identify areas for improvement by breaking down their strengths and flaws.
• My abilities were much enhanced by this project, particularly in the areas of interactive quiz creation, Firebase, and real-time data processing. learned a great deal in the process!
• Problem 1:
• Because of traffic and the number of students using the platform, we run into performance issues in the analysis report.
• Solution.
• We didn't have an initial queue, which made some requests throttle. We easily fixed it by adding a queue and processing data in batches, so it lowered the database as well.
• Solution:
• We refactored our code, replacing React Context with Redux. The issue was that we used a single context for the whole application, causing unnecessary re-renders. Instead of creating multiple contexts, Redux efficiently manages state by ensuring only the components that depend on updated values re-render, improving performance.
