About this gig

Are you dealing with Minecraft modpack crashes, errors, lag, or failed conversions between Forge and Fabric?


I help server owners and players fix, optimize, and convert Minecraft modpacks so everything runs smoothly and reliably.


I specialize in Minecraft modpack troubleshooting, Forge to Fabric conversion, performance optimization, and compatibility fixes. Whether your modpack wont launch, crashes mid-game, has version conflicts, or needs to be converted for Fabric or Quilt, I identify the root cause and fix it properly.


My Services:

  • Fix Minecraft modpack errors & crashes
  • Convert Forge modpacks to Fabric (and vice versa)
  • Optimize modpack performance & reduce lag
  • Resolve CurseForge install & version issues
  • Remove or replace broken or incompatible mods
  • Prepare modpacks for singleplayer or servers


What you'll get:

  • Clear diagnosis & clean fixes
  • Stable, optimized modpack
  • Tested compatibility
  • Professional communication


I understand modpacks are complex projects. I work carefully to protect your files and deliver reliable results.


Message me before ordering so I can review your setup and recommend the best solution.
