Experience

Quality Assurance Intern, GHz-Tech

From May 2025 – July 2025

• Independently executed end-to-end UI functionality testing for a hospital information system (HIS) mobile application prior to internal release.
• Wrote and maintained 100+ structured test cases based on UX prototypes and design documentation, with emphasis on ambiguity resolution and boundary behavior; identified 21 functional bugs and 4 usability issues, including 4 bugs not previously discovered by the primary QA lead.
• Collaborated with the QA engineer to cross-verify defects and coordinate issue triage and resolution with frontend/backend developers via internal tracking platform.
• Prioritized reported issues by risk level and impact on user workflow, enabling faster response cycles during development sprints.
• Submitted bug reports with reproduction steps and annotated screenshots, and verified fixes post-deployment.
• Supported UI iteration based on shifting client feedback, updating component layouts and interaction flow in Figma.

Undergraduate Research Assistant, CUHK(SZ)

From August 2023 - July 2024

• Developed and implemented a web crawler to automatically retrieve ESG reports from corporate websites, enhancing data acquisition efficiency.
• Converted PDF documents into text, increasing data accuracy and reliability.
• Employed advanced large language models to extract critical information from text, streamlining the data processing workflow.
• Created well-designed prompt, significantly reducing the incidence of hallucinated or inaccurate data by 4%, bolstering the integrity of research outcomes.

Finance Officer, CUHK(SZ) IEEE Student Branch

From August 2023 - July 2024

• Pioneered the establishment of the finance department to professionalize budget management and financial oversight, previously managed by the branch leader.
• Initiated and managed a reimbursement project for IEEE membership fees, funded by the School of Science and Engineering, to boost student membership in the global IEEE community.

Projects

UBC Course Visual Planner

I builded a Course visualizing and planning tool to plan my future course and help other students in UBC. (The Python version is complete and can be found in the All-University Branch. Currently, my friends and I are working on the main branch, which is the website that has more functionalities.) View the project on GitHub

UBC MineCraft Player Engagement Analysis

This project analyzes player behavior on a UBC-hosted Minecraft server using player and session data. The goal is to identify which types of players contribute the most data, aiding targeted recruitment for future research. View the project on GitHub

ESG Report Information Extraction

A private project where I work with two other people to use OpenAI's API to extract valuable insights from ESG reports and analyze the data we get.

Due to the nature of the project, this cannot be shared publicly.
