Kinetic art installation using PID control algorithms to determine stepper motor acceleration/deceleration for circular motion via force gauge feedback.

Led the payment and order systems team. Built payment infrastructure from database design to microservices, integrating Stripe, TapPay, virtual accounts, and custom reconciliation. Resolved production memory leak (40% to 3%).

NFT IP archery-like game. Implemented battle system, leaderboard, and server-side anti-cheat validation.

Decentralized payment system supporting USDC/USDT on multiple EVM chains (Ethereum, Base, Arbitrum, Polygon, Optimism). Microservices architecture with payment verification via Alchemy webhooks and scheduled reconciliation.

Modern dance performance at National Theater where dancers perform alongside a robot. Built a custom Unity editor for choreography using Keyframe Animation, converting joint angles to stepper motor parameters.

Arcade gaming machine built with Unity, featuring main game loop, lottery modes, data persistence, and RS232 hardware communication. Stress-tested for 48+ hours on a 2GB Android board with zero memory leaks.

2D fighting game with 3D characters rendered in cartoon style. Implemented control system, move system refinements, and behavior tree AI modules.

2D scrolling roguelike game built with Unity. Set up the project foundation with behavior trees, localization, Google Spreadsheet integration for data-driven development, and AI behavior design.

Vampire Survivors-like game using ECS framework for thousands of entities without lag. Implemented 2D skeletal animation rendering, Genshin-inspired numerical systems, 2D physics collision, and Hybrid ECS.

Full-cycle circuit design and PCB delivery for a compact embedded controller board — schematic capture, mixed digital/analog power sections, and fabrication-ready outputs.

Quantitative trading strategy for Taiwan stock market using Finlab. Includes factor discovery, analysis, combination, backtesting, and overfitting validation. Achieved +59.0% annual return, -21.3% MDD, 2.2 Sharpe ratio.

Multimedia system built with Unity handling multiple image sources (USB cameras, networked feeds, game outputs). Used Spout texture sharing for projection mapping and dynamic lighting control via Shaders and MadMapper.

Hardware communication and control system using RS485 between modules. A computer receives network packets from the artist and sends serial commands to stepper motors via microcontrollers.

Cryptocurrency signal platform frontend with AWS cloud architecture integration.

Web3 project built on Sui blockchain for decentralized content storage. Built an Indexer to cache on-chain data in a centralized DB, improving traditional Web3 UX.
