GoSchoolBox is a SaaS platform serving as the backbone for school districts and tutoring companies, enabling seamless connection and operational management. As the platform grew from 50,000 to over 1 million users, performance bottlenecks and stability issues emerged, including slow page loads, gateway timeouts, and inconsistent user experiences. In this project, I focused on profiling and optimizing the Node.js back-end logic, identifying and fixing performance bottlenecks to improve server throughput and responsiveness. I implemented Application Performance Monitoring (APM) tools to monitor real-time performance metrics and refactored critical workflows to ensure efficiency under heavy loads. Additionally, I optimized MongoDB queries to handle millions of records seamlessly, significantly reducing query times and enhancing overall performance. These improvements stabilized the platform, allowing it to scale effectively while delivering a fast, consistent experience for end users.
