I will fix unreal engine multiplayer and replication issues
Wanderson L
About this gig
I will diagnose and fix multiplayer, replication, and networking issues in Unreal Engine projects using C++ and/or Blueprints.
I have 6+ years of professional Unreal Engine experience across shipped and live multiplayer games, working with server-authoritative systems, replicated state, dedicated-server environments, gameplay systems, debugging, and runtime stability.
I can help with issues such as:
- Replicated variables and state synchronization
- RPCs and client/server communication
- Authority and ownership problems
- Server-authoritative gameplay logic
- Listen server and dedicated server issues
- Multiplayer desynchronization
- Replicated gameplay components and mechanics
- C++ / Blueprint networking integration
- Difficult-to-reproduce multiplayer bugs
I focus on identifying the root cause and providing a clean, maintainable fix rather than masking synchronization problems with temporary workarounds.
Please contact me before ordering if the issue involves major multiplayer architecture changes, converting a single-player system to multiplayer, backend infrastructure, or multiple unrelated networking systems.

FAQ
1. What do you need from me before starting?
Please provide your Unreal Engine version, clear reproduction steps, expected and actual behavior, relevant logs or videos, and access to the affected code or project files when necessary.
2. What counts as one multiplayer issue?
One issue is a clearly defined reproducible networking or replication problem. Multiple symptoms caused by the same root cause may count as one issue. Unrelated networking problems require a larger package or custom offer.
3. Do you work with both C++ and Blueprints?
Yes. I work with Unreal Engine networking in C++, Blueprints, and projects that combine both.
4. Can you work with dedicated servers?
Yes. I have professional experience investigating multiplayer behavior across client and dedicated-server environments. Dedicated-server validation can also be added as an extra when applicable.
5. Can you fix RPC, authority, and ownership problems?
Yes. I can investigate RPC behavior, actor ownership, authority, replicated properties, state synchronization, and related client/server logic.
6. Can you convert my single-player game or system to multiplayer?
Potentially, but full multiplayer conversion is outside the standard scope of this Gig. Significant architectural changes usually require a custom offer after reviewing the project.
7. Can you fix lag or network performance problems?
I can investigate replication frequency, network behavior, synchronization, and gameplay-related networking bottlenecks. Infrastructure, hosting, or external network-service problems may require separate work.
8. What does a revision include?
A revision covers adjustments or corrections within the originally agreed scope. Additional networking issues, new multiplayer features, architectural changes, or new requirements are not revisions.
9. Can you implement a new multiplayer feature instead of fixing one?
Yes, but new feature development is outside the standard scope of this Gig. I can provide a custom offer based on the feature, replication requirements, and integration complexity.
