Submitty
I participated in full stack development in Linux, utilizing a diverse set of programming languages including PHP, JavaScript, C++ and Python. I made notable modifications to the auto-grader, code difference viewer, PDF annotation, and other front-end features such as simple grading to to enhance user experience and operational efficiency.
Submitty is an open-source course management and grading system primarily used by the Computer Science department at Rensselaer Polytechnic Institute. Upon joining the team, I dedicated the initial month to familiarizing myself with Submitty’s architecture, alongside gaining a foundational understanding of languages including PHP and JavaScript. Then, as I became more familiar with Submitty, I focused mainly on enhancing front end features such as simple grading. Additionally, I enhanced various PDF functionalities within the grading interface, particularly the PDF annotation feature, enabling graders to overlay custom marks on submitted PDF files during evaluation. I also speny a significant amount of time to refining the expected string feature, which allows the use of expected_string within assignment configurations. If you want to learn more about my code contribuations, here is a complete list of my commits on GitHub.

Working at Submitty allowed me to learn about techniques and further understand the principles behind practical applications. I will continue to contribute in my free time.
