About me

Muhammad Andriansyah

Full-stack Roblox systems programmer since 2018. I build what a multiplayer game stands on, from server authority and player data to the interface, cameras, and cutscenes players see, for studios, brands, and indie teams in Indonesia and abroad.

  • Server Systems and Player Data

    Validated networking, session-locked saves, economies, matchmaking, and NPC AI, with the server deciding every outcome and saves that survive a crash.

  • Client Experience and Interface

    Responsive UI and HUD for mobile and PC, custom cameras and input, VFX, tweens, and cutscenes, so what players see matches what the server knows.

  • Team Coordination and Tooling

    Coordinated the programming team at Topic Indonesia, and build open-source tools such as Twill and Roblox Optimum for other Roblox developers.

Studios I have shipped with

19.1M visits, 370.9K favorites, and 29.5K likes on featured games, live from Roblox.

Soft skills

  • Team Coordination

    I coordinated the programming team at Topic Indonesia. I set the technical direction, make the call when the team is split, and keep the build moving.

  • Efficiency First

    I remove what slows a team down, in code and in process: fewer manual steps, fewer repeated bugs, less rework.

  • Ownership and Drive

    I take a system from the first draft to the live game, and I stay responsible for it after launch.

  • Clear Communication

    I explain technical trade-offs in plain words to designers, artists, and brand clients.
