LI, Yu Hong Harry | 李LI裕康Yu Hong

After performing outstandingly in the computer science courses. Instructors invited me to serve as a undergraduate teaching assistant (UGTA) for the course. As of 2024-25 Summer, I have served as a UGTA for 6 semesters (including Summer and Winter) throughout 3 courses (COMP 2011, 2012 and 1023).

• Assisting instructors in preparing course materials, including assignments, tutorial notes, lecture notes and self-tests.
• Answering students' questions and providing guidance on lecture materials, assignments, environment set-up, as well as introducing advanced topics to students if they are interested.
• Writing guides and instructions for students to set-up the programming environment and to debug complex issues in programs.

• Leading the backend team in refactoring the backend server architecture into a containerized microservice architecture, in order to improve performance and maintainability.
• Leading the app team in revamping our old apps, migrating them from old native apps for Android and iOS, respectively, into one app built with React Native technology.
• Leading the team in refactoring the CI/CD workflow of the development process of both the backend team and the app team, automatizing, simplifying and improving the efficiency of the integration and deployment / release process.

Supervised by Professor Lionel Parreaux, I implemented the language feature type classes in MLscript, an object-oriented and functional programming language founded and led by Professor Lionel Parreaux. In particular, I implemented:

• Functions with multiple parameter lists.
• Module methods, a type of methods (functions) or methods that require extra handling by compiler on call site.
• Type classes, including contextual parameters and given instances.

A new pass was being added to the compiler to effectively support the new features. Now, I am continuing working on the new pass to support other features that requires call-site handling.
