- Developed, tested, and maintained an internally used automatic bill calculation system.
- Updated and maintained the company database; Analyzed the database structure; designed and modified the structure to cater to different use cases.
- Designed the Microsoft Power Automate pipeline to Use Excel Online to write Office Script to automatically fill in charging rates, amounts, and dates into the daily form.
- Matched and extracted essential information such as tracking numbers and prices from large, noisy data provided by clients for usage by other departments, which improved the working efficiency by over 60%.

- Physics Informed Neural Network for Battery Modeling Project.
- Solved partial differential equations to improve the current battery models with Physics Informed Neural Network (PINN)
- Conducted literature survey on PINN, SPM, and Lithium batteries; Collected, cleansed data, prepared data for data visualization, and applied exploratory analysis.
- Developed the Physics Informal Neural Network from scratch, fitted the model to existing data, and analyzed the PINN model.

Tutoring Statistics, Math, Computer Science, and Data Science courses at UBC and SFU.

- Collaborated with Borealis AI, a research institute of RBC.
- Applied and evaluated advanced machine learning models, including Regularized Regression, Neural Networks, Time Series models, etc., to predict local emergency department demands.
- Performed in-depth feature creation by appending climate, holiday, and demography data to enhance analysis.
- Kept identifying opportunities for adaption and refinement, and seeking collaboration with local hospitals or public health agencies.

- Performed early-stage raw data collection via public channels, including National Statistics Bureau, FRED, etc.
- Applied Naive Bayesian analysis, KNN, and SVM strategies for model construction and autonomous testing.
- Applied classical statistical methods, including confidence and prediction intervals and their calibration to evaluate models.
- Adopted transformers including SVD and PCA for model improvements.

- Implemented and evaluated various machine learning models (k-nearest neighbor, decision tree, support vector machine, and logistic regression) to classify animal specifies based on physical features.
- Developed a reproducible pipeline for the classification problem, and integrated the pipeline using Docker.
- Developed, maintained, and published Python packages encapsulating commonly used functions in the pipeline to enhance reproducibility.

- Developed an full stack application from scratch using Django framework and SQLite.
- Implemented a database modelling functions on services, employment management, and amusement facilities.
- Performed database structure analysis, and normalized the relations among tables to reduce redundancy.
- Designed the user interface of the application with the Bootstrap template.

- Developed in the progress of both console-based and GUI-based versions and maintained simple transitions.
- A turn-based RPG where players engage in battles using a selection of spells, each with unique attack values, against progressively challenging enemies, enhancing the immersive Harry Potter-themed experience.
- Implemented a dynamic archive management system allowing players to choose from various wizards, each with distinct HP and ATK stats, adding strategic depth to battles and ensuring a varied gaming experience across different sessions.
- Included a well-designed interface, stories, characters and portraits.
