Automated Software Testing
Built an end-to-end automated testing framework spanning web and mobile apps, using Selenium for web testing and Appium/ADB for mobile UI control. AI coding agents like Codex and Antigravity helped speed up test script development, shortening regression testing and release validation time.

Automated Data Reporting / Sync
Used Google Apps Script to automatically pull data from multiple sources on a schedule, cleaning and consolidating it through an ETL pipeline to produce Excel and Google Sheets reports synced to the cloud — giving teams real-time visibility into operations without manual compilation.

LINE LIFF Custom Forms / Admin Dashboard
Developed custom in-app forms using LINE LIFF (LINE's front-end framework for mini-apps) and a backend admin system, using the LINE Messaging API for message interactions and notifications. Built with a React frontend and a Node.js backend connected to Firebase and Cloudflare D1, deployed on Cloudflare — providing a one-stop interface for real-time order intake, review, and data management.
