Online Learning Platform
- Pynest collaborated with an online learning platform that offers educational programs from top universities all over the world and industry leaders. The platform provides more than 50 current topics and 200 courses designed to keep users engaged from start to finish. The goal was to enhance platform functionality, improve performance, and ensure seamless integration with third-party services.
Client
The client is a leading online education platform that partners with prestigious universities and organizations to offer high-quality courses. Their mission is to provide accessible and practical knowledge to learners across the world. Detailed information about the client cannot be disclosed under the provisions of the NDA.
Challenge
The client needed to expand the core functionality of their learning management system (LMS), optimize slow SQL queries, and integrate new third-party services. The platform required better handling of deferred tasks and improved system performance to ensure a seamless user experience.
Solution
Our development team restructured the platform by enhancing the backend architecture, optimizing SQL queries, and designing efficient workflows using Django, Kafka, and Celery. We ensured the system could handle high traffic loads while maintaining optimal performance.
