My Projects
Here are some of the projects I have worked on, showcasing my skills in cybersecurity, IT operations, and leadership. Each project highlights my involvement, work process, and the results achieved.
FortiFile Project
Problem / Scope
Nanyang Polytechnic needed a secure file management system to control user access and maintain accountability for sensitive operations. The challenge was to implement robust security controls while ensuring the system remained user-friendly for administrators.
My Role & Solution
As the lead developer, I designed and implemented a comprehensive security solution featuring session-based authentication, role-based access control (RBAC), and detailed audit logging. My approach focused on separating user and administrator privileges while maintaining full traceability.
Work Process
I developed secure authentication with session handling, enforced RBAC to separate user and administrator privileges, created audit logging to capture all user actions and security events, and built an administrative dashboard for monitoring, filtering, and CSV export.
Outcome & Results
The project achieved controlled access, enhanced accountability, and provided comprehensive visibility into user activities. It effectively supports secure operations and incident investigation through detailed logging and monitoring capabilities.
FortiFile Project 2
Problem / Scope
Building on the success of the first FortiFile project, there was a need to enhance the system with additional security features and improved performance for handling larger datasets and more concurrent users.
My Role & Solution
I led the second iteration of the project, focusing on optimizing database queries, implementing additional security layers, and improving the user interface based on feedback from the first deployment.
Work Process
I conducted code reviews and security audits of the existing system, implemented performance optimizations for database operations, added new security features based on vulnerability assessments, and enhanced the dashboard with real-time monitoring capabilities.
Outcome & Results
The enhanced system demonstrated improved performance with faster query response times and better handling of concurrent users. Security audits confirmed the effectiveness of the new protective measures implemented.
Spring Gala 2025 - Japanese Exchange
Problem / Scope
Nanyang Polytechnic hosted the Japanese Exchange Programme 2025 with 60+ participants from Japan. The challenge was to coordinate logistics, manage schedules, and ensure smooth cross-cultural communication throughout the event.
My Role & Solution
As Vice President of the Chinese Cultural Group, I oversaw live operations for the exchange programme, managing schedules, manpower deployment, and issue resolution to ensure smooth execution.
Work Process
I coordinated with multiple school departments and stakeholders, created detailed schedules and contingency plans, managed on-site operations and real-time problem-solving, and facilitated cross-cultural activities and communication.
Outcome & Results
The exchange programme was successfully executed with positive feedback from Japanese participants and school administration. All scheduled activities were completed on time with no major issues.
Spring Gala 2026
Problem / Scope
The Chinese Cultural Group at Nanyang Polytechnic needed to plan and execute Spring Gala 2026, a large-scale cultural event with over 400 participants. This required end-to-end planning including proposal writing, inter-department liaison, and on-site operations.
My Role & Solution
As Vice President, I led the end-to-end planning and execution of the event. My approach involved systematic project management, clear communication channels, and proactive stakeholder engagement.
Work Process
I managed proposal writing and budget planning, coordinated inter-department liaison and approvals, organized manpower recruitment and training, oversaw rehearsals and on-site operations, and handled real-time issue resolution during the event.
Outcome & Results
Spring Gala 2026 was successfully executed with over 400 participants. The event promoted Chinese cultural awareness and engagement across the school community, receiving positive feedback from attendees and school administration.
IT Lab Management System
Problem / Scope
Nanyang Polytechnic IT department needed to maintain consistent lab baselines across 50+ iMac and Windows PCs per semester, while ensuring minimal disruption to lessons and events.
My Role & Solution
As IT Support & Operations Assistant, I managed the imaging and deployment process using FOG Project and Azure MDM. I developed systematic approaches for preventive maintenance and device policy management.
Work Process
I executed imaging and deployment for 50+ devices per semester, performed scheduled preventive maintenance 4-6 times annually, monitored and resolved technical issues via NetSupport, supported Windows account access and device policies via Azure MDM, and automated routine tasks to reduce manual workload.
Outcome & Results
Maintained consistent lab baselines with improved system reliability and uptime. The automation of routine tasks significantly reduced manual workload and response time for technical issues.
