During my tenure as a developer, I contributed to the development of an online class platform with an exam and task monitoring system. This innovative solution, built using .NET Core Web API, Angular, WinForm, and SQL Server, aimed to enhance the teaching and learning experience in a virtual setting. Key features of the project included a comprehensive cheat detection system, ensuring the integrity of online exams. The system effectively monitored and tracked student activity during exams, allowing teachers to detect any suspicious behavior. Effort estimation functionality was implemented to provide insights into the time students spent on performing online tasks. This feature allowed teachers to evaluate student engagement and optimize the learning process. To facilitate real-time monitoring, a teacher dashboard was developed. This dashboard enabled teachers to track student participation and determine whether students were actively engaged in the online class. The system automatically captured screenshots of student activities and securely transmitted them to the server for review and analysis. The project also incorporated additional functionalities such as basic chat, online class modules, and an exam board for students, creating a comprehensive and interactive online learning environment. Through this project, I gained hands-on experience in utilizing .NET Core Web API, Angular, WinForm, and SQL Server, while focusing on critical aspects such as cheat detection, effort estimation, and real-time monitoring. This project not only contributed to the advancement of online education but also honed my skills in developing robust and user-centric applications.
