Infomax

Freelance Developer · Mar 2024 - Mar 2024

Built the shared API foundation for an MCQ learning platform, with versioned Express routes, request protection, email error notifications, and deployment configuration. Learning-domain operations remain scaffold implementations.

More about this engagement

Organized questions, exams, courses, enrolment, and results into versioned Express modules for an MCQ learning platform. Centralized controller wrappers, response formatting, and error handling to give new features a consistent API structure. Added Helmet security headers, request limits, timeouts, and rate limiting at the application boundary. Included Nodemailer error notifications and Docker/PM2 deployment configuration. The reviewed implementation establishes API infrastructure; persisted learning workflows, exam execution, and result storage remain incomplete.
