About this gig
Hello!
Is your modpack crashing, lagging, or failing to launch? I will create, fix, optimize, or convert your Minecraft Java modpack.
SERVICES: CREATE: Custom modpacks with compatible mods, dependencies, configs, progression, and CurseForge/Modrinth exports. FIX: Crash reports, latest.log errors, missing dependencies, mod conflicts, startup, and client/server issues.
OPTIMIZE: Startup, RAM, client FPS, server MSPT/TPS, CPU, entities, chunks, and configurations.
CONVERT: Forge, Fabric, and NeoForge migration assessment and compatibility work.
DEVELOP: Scoped Java mods, plugins, datapacks, commands, recipes, and gameplay systems.
I review your files and logs, apply the agreed work, test your scenario, and deliver files. Conversion depends on mod availability, APIs, mappings, versions, and dependencies. Optimization depends on hardware and hosting; no universal lag-free or fixed-FPS guarantee is promised.
Message me before ordering for large packs, live servers, conversions, custom code, or quests. Send your Minecraft version, loader, mod list, logs, requirements, and target environment. Never send passwords; use a safe copy or staging server.

FAQ
Do you guarantee no future crashes?
No. I test the agreed scenario and address the agreed issue, but third-party updates, hardware, Java, world state, shaders, hosting, and later mod changes can introduce new failures.
Can you install directly on my host?
Staging or host-panel installation can be included only when agreed, supported by the host, and safely scoped. Provide a backup and never send your main account password. Temporary or limited access is preferred.
Will you publish my pack on CurseForge or Modrinth?
I can prepare a compatible export and provide upload guidance. Publishing or redistributing third-party content depends on the relevant licenses, permissions, and platform rules. I do not claim ownership of included mods.
Do your standard packages include custom mod or plugin programming?
No. Modpack creation/configuration is different from writing new Java code. Custom mods, plugins, datapacks, integrations, and feature systems need their own feature list, acceptance criteria, and quote.
What does optimization include?
It may include configuration review, dependency cleanup, JVM/RAM recommendations, client performance checks, or server profiling for MSPT/TPS, entities, chunks, and startup. Results depend on the agreed hardware, world, player load, and test environment.
