During my previous job as a Senior Full Stack .Net Developer at XYZ Corp, I encountered a complex technical challenge while working on a project to develop a web application for a large-scale e-commerce platform. The challenge was related to optimizing the application's performance to handle high user traffic during peak hours while ensuring scalability and reliability.
As the project lead, I approached this challenge by first identifying the bottleneck areas in the application and analyzing the existing code to identify areas of optimization. After a thorough evaluation, I discovered that the application's database queries were causing the most significant performance lag. To resolve this issue, I implemented a caching mechanism which significantly improved the performance of the application.
Furthermore, I introduced a load balancing mechanism which automatically allocated resources to the application servers based on the user traffic. The load balancing mechanism also ensured that the user requests were evenly distributed across the servers to avoid any single point of failure.
The end result was that the application performance was significantly improved, and it now handled high user traffic during peak hours. The application was also highly scalable and reliable due to the implementation of the caching and load balancing mechanisms.
