About this gig
Seen "Game crashed on startup", "Exit code 1" or "Missing registry entries"? Or a mod that worked yesterday and doesn't today? I read the crash log, find the real cause, and fix it. I can also speed up your pack or build a new one around your theme.
WHAT I HANDLE:
Crash log reading
+ Exit code 1 errors
+ Startup crash fixes
+ Mixin conflicts
+ Mod conflicts
+ Dependency issues
+ Missing libraries
+ Loader errors
+ Java version mismatch
+ Launcher problems
+ Out of memory errors
+ GC overhead errors
+ Ticking entity errors
+ World corruption
+ Chunk errors
+ Missing registry entries
+ Recipe and loot conflicts
+ Texture and model bugs
+ Shader and Sodium issues
+ Sound and GUI bugs
+ Keybind conflicts
+ Client/server mismatch
+ Broken mod detection
+ Modpack rebuilds
+ Folder cleanup
+ Version updates
+ Rollbacks
+ Launcher migration

If you've ever stared at a crash screen at 2 a.m. wondering which mod broke everything, you know why I do this. I rescue modpacks that won't launch, code custom mods and convert them between Forge, Fabric and NeoForge, build datapacks, plugins, and set up servers that are ready for launch day. I've worked with Minecraft for 2 years, and I'd rather find the real cause than guess. Send me your crash log, your idea and I'll tell you honestly what's possible and what it'll take.
I model in SketchUp and Revit, with realistic interior and exterior renders, 3D floor plans and BIM models.
FAQ
Can you make my pack run faster too?
A: Yes: FPS, memory, and load time. Results depend on your hardware, and I'll send before and after numbers.A: Yes: FPS, memory, and load time. Results depend on your hardware, and I'll send before and after numbers.
