About me

Hi! I'm Kexiang (KX) Shuai, a game client and XR developer working with Unity. My work spans gameplay systems, multiplayer spatial experiences, and tools that help teams build and debug more effectively.

I'm pursuing a master's degree at Carnegie Mellon University's Entertainment Technology Center. At Tencent Games' TiMi Studio Group, I worked on gameplay systems, Unity editor tools, and development workflows. I also bring three years of HCI research experience from HER Lab.

Internships

  1. Game Client Development Intern · Tencent Games, TiMi Studio Group

    May 2026 – Aug 2026
    • Delivered a new gameplay formation system and adapted the hero display interface for acceptance. Extracted a shared base class for old and new formation systems, kept extension points, and removed redundant logic. Maintained both modules and resolved 26 bugs with design, art, and backend teams.
    • Fixed item navigation, duplicate-name search, and refresh issues in the Unity attribute inspector. Built an MCP interface that lets AI agents read runtime attribute data as structured debugging context.
    • Added project constraints, custom skills, and a refine-change step to an OpenSpec and Agent Harness workflow so requirements could be checked before implementation.
    • Built a specification review workbench for designers using CodeBuddy CLI and Agent SDK, with IOA authentication, issue severity levels, human diff approval, and review reminders. The tool entered team trial use.
  2. Software Development Intern · Bosch (China) Investment Ltd.

    Apr 2024 – Aug 2024
    • Redesigned and developed gesture interaction for production-line training in AR, iterating with internal stakeholders; internal customer satisfaction rose 20%.
    • Rebuilt a warehouse navigation app in Unity and migrated it to Apple Vision Pro. Integrated ERP inventory data with the physical environment to locate goods in real space.

Games & Projects

  1. Capybara vs. Granny · Local Multiplayer Party Game

    Nov 2025 – Dec 2025
    • Implemented health, hit detection, death, respawn, and environmental destruction in Unity for local multiplayer combat.
    • Built a capybara stacking mechanic by coordinating player state, physics constraints, and input timing.
    • Completed seven prototype iterations across six playtest rounds in a three-week development cycle, refining edge cases before delivery.
  2. Digital Touch · Colocated visionOS Collaboration

    Jul 2025 – Aug 2025
    • Helped build a Unity transport plugin using Apple Multipeer Connectivity for local peer-to-peer communication without an external Wi-Fi access point or cellular network.
    • Connected the transport to Unity Netcode for real-time content synchronization and spatial alignment across colocated visionOS devices. Submitted to Augmented Humans.
  3. HeritageSite AR · Suzhou Twin Pagodas Exploration Game

    Nov 2022 – Dec 2022
    • Interviewed four heritage specialists and collected 174 visitor questionnaires to identify needs in interpretation, route guidance, and visit recall.
    • Implemented story-driven puzzles, NPC dialogue, and interactive 3D ruins in Unity; the game was deployed on site.
    • User evaluation recorded 56% appreciation for the interactive experience and 42% knowledge acquisition. Results appeared at CHI 2023 and in JOCCH.

Additional Projects & Research
