I will develop multiplayer replicated ai npc systems,vehicle physics in unreal engine 5

About this gig
Are your NPCs desyncing in multiplayer, or does your vehicle physics feel floaty and unrealistic? You've found the right gig.
I'm a dedicated Unreal Engine 5 developer specializing in two of the hardest problems in game development: networked AI behavior and vehicle physics simulation. While most Unreal developers treat multiplayer AI and vehicles as an afterthought, I focus specifically on making these systems work correctly, sync properly across clients, and feel great to play.
What I Offer:
- Server authoritative AI with proper client replication (Behavior Trees, Blackboards, State Trees)
- Fixing AI desync, rubber banding, and inconsistent behavior in multiplayer
- Perception, combat, and patrol/chase/attack states that replicate cleanly
- Custom vehicle physics (Chaos Vehicle) cars, bikes, tanks, aircraft
- Realistic handling, suspension, traction, and replicated vehicle movement with no jitter
I deliver clean, scalable Blueprint and/or C++ code, built to be extended not thrown away with clear communication throughout.
Contact me today to get started.

FAQ
Do you work with Blueprints, C++, or both?
Both. I use Blueprints for rapid iteration and C++ for performance critical replication logic whichever fits your project's existing codebase.
Can you fix an existing broken AI or vehicle system instead of building from scratch?
Yes. Debugging existing replicated AI or vehicle physics is one of my core services, just share your project file and a description of the issue.
Does this work for both PC and console multiplayer?
Yes, replication logic is built to be platform agnostic, though I'll flag any platform specific certification requirements if they apply.
What engine version do you support?
Unreal Engine 5 and 4 (all versions). Let me know your exact version before ordering to confirm compatibility.
