I help game creators turn ideas into playable, polished experiences. For Roblox, I work on combat animations, VFX, Luau scripting, abilities, UI, maps and bug fixes. For Minecraft, I can help with custom builds, maps, server setup and gameplay features. I also create game trailers, thumbnails and short videos that show the best parts of a project. Tell me what you are building, what already works and where you need help. I will review the scope, agree on clear deliverables and keep you updated as the work moves forward.

FAQ
Can you fix my Minecraft modpack crashing on startup or showing Exit Code 1?
Yes. I troubleshoot Minecraft modpack crashes, Exit Code 1, startup failures, and black screens. I review your crash report and latest.log to check broken mods, missing dependencies, Java versions, or loader conflicts in Forge, Fabric, and NeoForge before agreeing on a fix.
Can you fix Forge, Fabric, or NeoForge mod conflicts and missing dependencies?
I investigate Forge, Fabric, and NeoForge mod conflicts, missing libraries, wrong Minecraft versions, and incompatible modloader builds. Send your mod list, Minecraft version, and error log. I test compatible changes where possible and explain any mods that cannot work together.
Do you fix CurseForge, Modrinth, and Prism Launcher modpack errors?
Yes. I can diagnose CurseForge, Modrinth, and Prism Launcher installation errors, failed downloads, broken instances, modpack launch failures, and Java runtime settings. Share the launcher name, Minecraft version, screenshots, and logs so I can check the issue and scope.
Can you optimize Minecraft modpack FPS, lag, stuttering, and freezing?
I check Minecraft modpack FPS drops, stuttering, freezing, long load times, and memory issues. I review Java and RAM settings, mod conflicts, and performance options. Results depend on your PC specifications and pack size, so I cannot guarantee a specific FPS increase.
Can you fix a modpack that stopped working after a Minecraft update?
Yes. I investigate Minecraft modpack update failures, changed mod versions, loader mismatches, missing dependencies, and startup crashes after updates. I check compatibility and backups before changing files. Major mod rewrites or unavailable updates may need separate work.
Do you fix Cobblemon, Pixelmon, or RLCraft modpack issues?
I can troubleshoot Cobblemon, Pixelmon, RLCraft, and other Minecraft modpacks for launch crashes, conflicting mods, missing dependencies, and configuration errors. Please send the exact pack version and logs. Some mod-specific coding bugs may require the original developer.
Can you fix modded Minecraft multiplayer and client-server mod mismatch errors?
I can investigate modded Minecraft multiplayer failures caused by mismatched client and server mods, wrong Forge or Fabric versions, missing dependencies, and configuration differences. Send logs from both sides if available. Network or hosting issues may need separate diagnosis.
Can you repair a Minecraft modded world that crashes while loading?
I can examine modded Minecraft world loading crashes, ticking entity errors, missing registry entries, and crashes after removing mods. I work from backups where possible and test changes on copies. Corrupted worlds or lost data cannot always be recovered or repaired.
Will you remove my favorite mods to make my Minecraft modpack work?
My goal is to preserve your preferred Minecraft mods whenever possible. I use crash logs, dependency checks, and controlled testing to isolate mod conflicts before changing files. If two mods are incompatible, I'll explain the options and request approval before removing anything.
What files do you need before I order a Minecraft modpack crash fix?
Please send your Minecraft version, Forge/Fabric/NeoForge loader version, CurseForge or Prism Launcher profile, mod list, crash report or latest.log, and a short description of the problem. For FPS optimization, include PC specs. I'll review the scope before you order.
