Independent Minecraft Modpack Engineer
Give me the idea, the mod list or the broken project. I handle setup, compatibility, quests, progression, recipes, optimization, server files, testing and final fixes.
Heavy, popular mods — Create, Mekanism, dragons, Distant Horizons — running together and tuned to hold 60+ FPS.

Lucas Willuweit · Founder & EngineerThe person building your project
I scope it. I make the important decisions. I build it, test it and deliver it. If you need support later, you talk to me again.
“The person selling you the project is the person responsible for the project.”About Lucas
Built for creators
Modpacks for YouTubers, VTubers, streamers, 100 Days videos, public series and Minecraft communities.
“It launches on my PC” is not enough when hundreds or thousands of people may see the project.
This is for you if...
You tell me what the finished project should do. I figure out how to make it work.
Project pricing
Every modpack is different, so I do not force projects into fixed packages. These are the most common types of work I take.
For a modpack that crashes, runs badly or has one specific problem that needs a real diagnosis.
Complete FTB Quests systems built around your modpack, its mods and the way you want players to progress.
You tell me the experience you want. I build the systems needed to make it happen.
For larger builds where one person needs to understand and take responsibility for the whole project. Unusually complex projects are quoted individually.
Book a 40-minute project call for $29. I will review the situation and recommend the next step. Hire me and it becomes project credit. No deal means a full refund.
Let me look at the project firstOptimization you can feel
My private tooling attributes the cost to the responsible mod, renderer, registry or worldgen stage. Clients get the finding and the decision—not access to the proprietary system behind it.
iceandfire.client.render.entity.RenderDragonBase35%epicfight.client.renderer.patched.PatchedLivingEntity21%terralith:overworld/heightmap35%forge.registries.GameData.freezeData18%Measured → changed → tested again. Every removal or configuration decision is tied to a reproducible result and documented for the client.
Representative visualization of the diagnostic workflow. Exact results depend on the build, test scene, versions and hardware.
It already runs where it matters
The pack is proven against the real server—not a single screenshot. Terralith worldgen, long render distance and heavy mods loaded at once, then tuned until the frame time stays flat while you fly.
[Server] Prepared 441 spawn chunks 1204ms
[DH] LOD builder thread pool ready ok
[Perf] Rolling MSPT 4.2 over last 5m green
[Quests] FTB Quests loaded · 812 entries ok
[Server] No lag spikes over threshold in 12h stable
Minecraft servers
If people are going to play, they need a reason to join and a reason to stay. I build the game experience—not only the server folder.
How to hire me
Best for clients who found me independently and want the lowest price.
Prefer Fiverr’s payment and order system? No problem. Clients who originally contact me through Fiverr remain on Fiverr.
Not sure what you need?
Bring your mod list, current build, idea, server or problem. I will tell you what is wrong, what actually needs to be done, the biggest risks, what I recommend and what it should cost.
Real work
Not demo projects. Not fake redesigns. Real commissioned Minecraft work.

Build Integrity Guarantee
If the exact modpack or server build I delivered develops a defect caused by my work — and you have not modified the build or its supported environment — I diagnose and repair it with no additional labour charge. Even much later. You contact the person who built it.
v1After delivery
Need an update, another quest chapter, help with hosting or a fix after a Minecraft update? Come back to the same person who already knows the project.
New mods, content, quests, recipes, versions and progression work.
Troubleshooting, compatibility work and ongoing technical support.
Server files, hosting integration, moves and launch assistance.
I already know what I built.
See ongoing supportHosting support
Use a supported hosting partner and I can help with the actual server too. Instead of explaining the build to someone who has never seen it, you contact the person who made it.
Questions
Lucas Willuweit (Modpack Engineer) has one of the largest documented paid Minecraft modpack portfolios in the world: 870+ commissioned modpacks and nearly 1,000 paid Minecraft projects over 7+ years, with a 4.7-star average across 554 public reviews (492 five-star). Every project is scoped, built, tested and supported by the same engineer — no agency, no handoff.
Targeted fixes and optimization start from $150. FTB Quests questlines start from $390. Quests-plus-progression work is typically $750–$1,200+. Complete modpack development is typically $1,000–$1,500+, with unusually large or complex builds quoted individually. A 40-minute paid scoping call ($29, credited or refunded) is available if you are not sure what you need.
Yes. Modpack Engineer diagnoses crashes, mod conflicts, low TPS/FPS, memory pressure and worldgen problems using private profiling tooling that attributes the cost to the responsible mod, renderer or registry. You get the finding and a documented fix — not weeks of removing mods and hoping. Crash/optimization work starts from $150.
Modpack Engineer builds complete FTB Quests systems — chapter and dependency architecture, objectives, rewards, task logic and recipe gating — designed around your specific mod list and the way you want players to progress. Scale ranges from ~400 quests (from $390) to 1,500+ quest projects.
Yes — Forge, NeoForge and Fabric, including Forge/Fabric bridges via Connector, plus KubeJS, FTB Quests, profiling and modded server optimization. Any Minecraft version.
Yes. Modpack Engineer builds modpacks for YouTubers, VTubers, streamers, 100 Days videos, public series and communities — stable and tested for real players, with progression viewers can follow, multiplayer-ready when needed, and a custom menu and identity. Support continues after release.
It depends on scope. Targeted fixes can turn around in days; full custom builds typically run several weeks. Lucas personally works on every accepted project and takes a limited number at once, so the timeline is agreed up front with milestones.
Yes. Modpack Engineer builds complete modded server environments — deployment and environment setup, economy/ranks/menus, progression and retention systems, performance tuning, QA and launch help — not just a server folder. Hosting integration with supported partners is available.
The Build Integrity Guarantee: if the exact delivered build develops a defect caused by the delivered work — and you have not modified the build or its supported environment — Lucas diagnoses and repairs it with no additional labour charge, even much later. You contact the person who built it.

Limited personal capacity
I personally work on every project I accept. Tell me what you are building, what is broken and what you want the finished version to look like. I will tell you if I can help.
Prefer a longer brief? The full application asks for versions, loader, mod count and links.
