Yoon
About this gig
Need an Unreal Engine 5 developer to build, extend, fix or take your game online? I'm Dongwok Yun, a UE4/UE5 programmer in C++ and Blueprint, and multiplayer is my strongest area.
What I do
Gameplay features and systems in C++ and/or Blueprint
Multiplayer: replication, RPCs, listen and dedicated servers, sessions and lobbies, Steam Online Subsystem
Dedicated server builds (Windows/Linux) + deploy to your AWS or GCP VM
Bug fixing: desync, crashes and logic bugs in existing projects
Prototypes and small-to-mid-size games for indie release
Performance optimization
Track record
Client multiplayer game (2024): UE dedicated server + cloud backend, ~100 concurrent players
5.0 from 35 reviews / 42 orders on Kmong, Korea's largest freelance marketplace
2 games on Steam: THE LAST BREATH (1-5 player online co-op) and Only go up
Client work: a UE5.6 C++ escape game; UE5 VR training for Konkuk University (Meta Quest)
How it works: send your design doc and assets, I estimate the schedule, you can check progress anytime, and I hand over the full source.
Programming only (no 3D art or animation). Message me before larger orders for a custom offer.
