Moodle Expert for Scalable E-Exam Platform

Moodle Expert Role Specification: We are seeking a highly experienced and expert Moodle Architect/Engineer to design, and implement a high-performance, scalable, and highly available Moodle platform specifically for online examinations. This platform will support a large user base of 500,000 to 1 million concurrent students during peak exam periods, with the capacity to handle multiple concurrent exams. The ideal candidate possesses deep technical expertise in Moodle, Linux server administration, database management (MySQL), caching technologies, authentication/authorization systems configuration, and high-availability architecture. This role requires a hands-on individual who can both architect the system and execute the implementation. Responsibilities: Architecture & Design: Design and architect a highly scalable and available Moodle platform capable of supporting 500,000 to 1 million concurrent users for online examinations. Develop a detailed architecture blueprint, including server specifications, load balancing strategies, database design, caching mechanisms, and security considerations. Select and integrate appropriate technologies and tools for monitoring, performance tuning, and system management. Design and implement robust backup and recovery strategies for the Moodle platform and its associated data. Implementation & Configuration: Experience working on Huawei Cloud or equivalent. Configure and manage hundreds of Linux servers in a load-balanced, high-availability cluster. Install, configure, and customize Moodle, including plugins and themes. Optimize the MySQL database backend for performance and scalability. Implement and manage caching solutions (e.g., Redis, Memcached) to improve response times. Integrate authentication and authorization systems (e.g., LDAP, SAML) for secure user access. Implement security best practices to protect the platform from vulnerabilities and attacks. Automate system administration tasks using scripting (e.g., Bash, Python). Performance Tuning & Optimization: Setup monitoring system for performance and identify bottlenecks. Optimize server configurations, database queries, and Moodle settings to maximize performance and scalability. Conduct load testing and performance testing to ensure the platform can handle peak exam loads. Create implementation plans for updates and patches to Moodle and related software. Develop comprehensive documentation for the platform. Collaboration & Communication: Collaborate with other teams (e.g., development, testing, support) to ensure seamless integration. Communicate effectively with stakeholders about system status, performance, and any issues. Qualifications: Bachelor's degree in Computer Science, Information Technology, or a related field. Master's degree preferred. Extensive experience (5+ years) in Moodle architecture, administration, and development. Deep expertise in Linux server administration, including configuration, optimization, and troubleshooting. Strong understanding of MySQL database administration, including performance tuning, replication, and backup/recovery. Proficiency in caching technologies (e.g., Redis, Memcached). Experience with authentication and authorization systems (e.g., LDAP, SAML). Solid understanding of high-availability architecture and load balancing techniques. Experience with scripting languages (e.g., Bash, Python). Excellent problem-solving and analytical skills. Strong communication and collaboration skills. Experience working in a large-scale, high-traffic environment is highly desirable. Familiarity with cloud services (e.g., Virtual machine, Relational Database as a Service, ElastiCache) is a plus. Experience with Moodle plugins and custom development is a plus. The expected timeline for the project is 3-6 months.
