About

I'm an engineer with six years of experience building Unity mobile apps, three of them published on iOS and Android, spanning IoT-connected devices, computer vision, and interactive 3D. I have also built and published a full-stack fitness app on my own, from the database and PHP API to the mobile front end. I recently completed an MSc in Artificial Intelligence in Ireland, where my thesis studied how AI-generated synthetic videos can augment limited real data for vision-based fall detection, and I published the resulting dataset on GitHub. Now I'm building tool-using AI agents that connect software, devices, and people, and writing about what breaks along the way.

Experience

  1. May 2019 – Aug 2025

    Senior Software Engineer (Unity)

    AISA Innotech Inc.

    Metaverse Social App · Lead Engineer

    2024 – 2025
    • Built a 3D plaza modeled on the area around Taipei 101 in Unity (C#), with Photon Fusion multiplayer for shared scenes, avatar movement, and real-time text chat on iOS and Android.
    • Added a virtual lecture hall where speakers present slides on an in-scene projection screen, and recreated real Taiwan landmarks using OpenStreetMap-based assets.

    Fashion App · Lead Engineer

    2022 – 2023
    • Built OpenCV virtual makeup for an e-commerce platform: face detection and landmark segmentation into lips, eyeshadow and eyebrows, with color blending.
    • Built clothing try-on from full-body photos: used OpenCV to locate the body and split it into upper and lower regions, then scaled background-removed garments to shoulder width, with manual adjustment for fit.
    • Led one engineer and one UI designer; mentored the engineer on Unity SDK selection and testing, then integrated his live-streaming module into the main app.

    Smart Coffee Scale App · Lead Engineer (sole developer)

    2021 – 2022
    • Integrated the hardware vendor's Bluetooth API and refreshed the UI every 0.25 s for continuous real-time pour-over tracking.
    • Implemented automatic Bluetooth reconnection and local storage of brew records and scale settings.

    Smart IoT Plug App · Front-end Engineer

    2019 – 2021
    • Built usage-statistics UI and alert notifications, and connected backend APIs with a teammate.
    • Implemented a voice interface with keyword-triggered commands and text-to-speech replies.
    • Handled App Store and Google Play releases end to end for three production apps.
  2. [2020 – 2021]

    Solo Developer

    Independent project

    Fitness & Nutrition Tracking App · Founder & Sole Developer

    [2020 – 2021]
    • Built the app end to end: designed the MySQL database for user accounts and daily food logs, wrote the PHP API, and developed the Unity (C#) mobile front end.
    • Published on Google Play and the App Store; reached about 3,000 registered users with no promotion.

Education

  1. 2025 – 2026

    MSc in Artificial Intelligence

    National College of Ireland (NCI) · Dublin, Ireland

    • Thesis: vision-based bed-fall detection using YOLOv8 pose keypoints and a classifier, augmented with 170 AI-generated synthetic videos (85 fall, 85 non-fall) made with Mage.space.
    • Synthetic augmentation raised ROC-AUC from 0.821 to 0.875 and PR-AUC from 0.772 to 0.863, and cut the false-positive rate by about 55%.
    • With a tuned decision threshold, sensitivity and specificity both reached about 0.80, versus about 0.76 for the real-data baseline.
    • Grade: First Class Honours
    • Synthetic video dataset (GitHub) ↗

  2. 2021 – 2023

    Bachelor of Computer Science and Information Engineering

    Minghsin University of Science and Technology (MUST) · Taiwan

    • Completed while working full-time as a software engineer.
  3. 2010 – 2014

    Bachelor of Applied Japanese

    Aletheia University (AU) · Taiwan
