Willie O
About this gig
Hello Buyers,
Need a Minecraft modpack that actually runs well? I'll build it, fix it, and optimize it.
I'm a Minecraft developer who sets up and repairs modpacks and servers for players, SMP owners, and communities. If your pack crashes, lags, or won't launch, I'll get it stable and ready to play.
What I can do:
- Custom modpacks: Forge packs built around your theme with balanced, compatible mods
- Fix crashes: conflicts, missing dependencies, version mismatches, bad configs
- Optimize performance: higher FPS, less lag, faster loading via JVM arguments, RAM allocation, and config tuning
- Paper and Forge servers: installation, plugins, permissions, whitelist, and backups
- SMP setup: claims, economy, anti-grief, spawn, warps
- Version updates and migrations without losing worlds
What you get: a tested, working modpack or server, clean configs, setup instructions, and post delivery support.
Not sure what you need? Message me your crash log or a short description, and I'll tell you what's possible.

FAQ
Which Minecraft versions and mod loaders do you support?
Most Java Edition versions, with Forge, Fabric, and Paper servers. Tell me your version before ordering and I'll confirm it's supported.
My modpack keeps crashing. Can you fix it?
Yes. Send your crash log or latest.log and your mod list. I'll find the cause, whether a mod conflict, missing dependency, or bad config, and fix it.
Can you make my modpack run faster?
Yes. I optimize FPS, lag, and load times with performance mods, JVM arguments, RAM allocation, and config tuning.
Do you set up servers too?
Yes. I set up Paper and Forge servers, install plugins, and configure permissions, whitelist, backups, and spawn.
Can you build a custom modpack from scratch?
Yes. Tell me your theme (tech, magic, adventure, vanilla+, etc.) and I'll build a balanced, tested pack around it.
Will my world and progress be safe?
I always work on a backup copy. Please send your world folder if you want it kept, and I'll migrate it carefully.
