About this service

Game crashing, lagging or full of bugs you can't crack? I jump into existing Unity and Unreal projects to squash bugs, fix crashes and boost frame rates without rewriting your whole codebase. I'm the developer you call when something is broken.

  • Bug diagnosis and fixing across gameplay, UI and logic
  • Crash and freeze troubleshooting with root-cause analysis
  • Performance profiling and frame-rate optimization
  • Memory leak detection and draw-call reduction
  • Build errors, plugin conflicts and platform-specific issues
  • Clear report of what was wrong and how I fixed it

With years of debugging messy inherited projects, I read other people's code fast and fix problems at the source instead of patching symptoms. You get a stable, smooth game and an explanation you can actually understand.

Send me your project and a description of the issue, and I'll diagnose it quickly with an honest estimate. Let's get your game running like it should.

Ho Chi Minh City-based game developer focused on casual and hyper-casual mobile titles in Unity. I build tight gameplay loops, ad integrations, and store-ready builds that retain players. Comfortable owning a project from prototype to launch. Quick to communicate and serious about quality.

Found a memory leak that two other devs missed and doubled my frame rate. Lifesaver. Hire him.

Fixed our launch-day crash in hours and explained exactly what caused it. Incredibly fast and clear.

Jumped into messy inherited code and cleaned up the bugs without breaking anything. Very impressed.

Solved most issues quickly. One bug took a second pass but he stuck with it until done.

Mobile build went from stuttering to silky smooth. The optimization report alone was worth it.
