Project

- Worked on example business data from Waze to improve user retention.

- Planned PACE strategy, conducted hypothesis test, modeled logistic regression, and developed machine learning model using random forest and XGBoost to predict user churn. 

- Analyzed the trend of the past 100 years of climate data collected in Les Cedres, Quebec.

- Incorporated FFT and denoise techniques for the seasonal data, discovering that over the past century, Quebec experienced an approximately 1.4 °C temperature increase 


Experience

I focused on teaching the underlying principles and concepts in mathematics and physics to provide an advanced learning experience, rather than solely teaching computation. I conducted tutoring sessions in a personalized, one-on-one environment, allowing for faster feedback. I also provided supplementary support in language-related courses such as English and History. 

As an LLM Code Content Reviewer, my role involved reviewing and analyzing existing code and prompt content to identify errors or mistakes in generated responses. I was responsible for modifying or improving the code and ensuring its quality and functionality. My primary section was in Python, but I also reviewed HTML/CSS, SQL, and Java.

As the leader of a student-led Recognized Study Group, I managed the weekly scheduling and participation of all members. My role demanded leadership and management skills to align our group sessions with the course syllabus, ensuring consistent study and research progress.

As an Attendant at Astro Amusements, I ensured the smooth operation of various games and rides during local events, festivals, and film shoots, including large-scale events such as the Canadian National Exhibition. My responsibilities primarily revolved around equipment maintenance, customer service, and cash handling.
