We are seeking a skilled full-stack developer to create a comprehensive online examination platform that will revolutionize digital assessment processes. The project requires developing a secure, user-friendly system serving both students and administrators, featuring timed examinations, randomized question delivery, and instant grading capabilities. The platform must include robust security measures such as multi-factor authentication, session management, and encryption of sensitive data. Key technical requirements encompass a modern frontend framework (React.js/Angular/Vue.js), reliable backend infrastructure (Node.js/Python/Java), and secure database management (MySQL/PostgreSQL). The system should support various question types, automated grading, performance analytics, and comprehensive administrative controls. Essential features include a configurable timer, question randomization algorithms, real-time progress saving, and detailed reporting capabilities. The ideal candidate should possess 3+ years of full-stack development experience, proven expertise in educational technology, and strong security implementation skills. The project timeline spans 3-4 months, divided into phases covering system design, core development, advanced features implementation, testing, and deployment. Deliverables include complete source code, comprehensive documentation, user manuals, and API documentation. Post-launch support and maintenance for three months are required.
