I will debug and fix unreal engine cpp or blueprint bugs
Wanderson L
About this gig
I will diagnose and fix bugs in Unreal Engine projects using C++ and/or Blueprints.
I have 6+ years of professional Unreal Engine experience working on shipped and live multiplayer games, with a strong focus on gameplay systems, debugging, replication, runtime stability, and performance.
I can help with issues such as:
- C++ compile or runtime errors
- Blueprint logic bugs
- Crashes and invalid states
- Gameplay system issues
- C++ / Blueprint integration problems
- Runtime and performance-related bugs
- Replication or multiplayer-related issues
- Difficult-to-trace Unreal Engine behavior
I focus on identifying the root cause and providing a clean, maintainable fix rather than applying temporary workarounds.
Please provide clear reproduction steps, relevant logs, screenshots/videos, and the affected code or project files when possible.
For new features, larger systems, or multiple unrelated issues, please contact me for a custom offer.

FAQ
1. What do you need from me before starting?
Please provide clear reproduction steps, the expected behavior, the actual behavior, relevant logs or error messages, screenshots or video when useful, and access to the affected code or project files when necessary.
2. What counts as one bug or issue?
One issue is a single reproducible problem with a defined expected behavior. Multiple symptoms caused by the same root cause may be treated as one issue. Unrelated bugs are considered separate issues and may require a larger package or custom offer.
3. Do you work with both C++ and Blueprints?
Yes. I work with Unreal Engine C++, Blueprints, and systems that combine both. I can also investigate issues involving communication between Blueprint and C++ code.
4. What does a revision include?
A revision covers adjustments or corrections within the originally agreed scope. New features, additional unrelated bugs, system redesigns, or changes in requirements are not considered revisions and may require a separate order or custom offer.
5. Can you fix multiplayer or replication issues?
Yes. I have professional experience with server-authoritative multiplayer, replicated state, dedicated-server environments, and Unreal Engine networking. Complex multiplayer or networking problems may require a custom offer depending on scope.
6. Can you fix a bug if I cannot reproduce it consistently?
Possibly. Intermittent issues can often be investigated using logs, call stacks, profiling, state inspection, and additional instrumentation. Please contact me before ordering if the issue is difficult or inconsistent to reproduce.
7. Can you implement a new feature instead of fixing a bug?
Yes, but new feature development is outside the scope of this Gig. I can provide a custom offer based on the system, complexity, integration requirements, and delivery time.
8. What Unreal Engine versions do you support?
I primarily work with UE4 and UE5. If your project uses a specific or older Unreal Engine version, please mention it before ordering so I can confirm compatibility.
