Jan B.

Top Rated Unreal Engine 5 developer (C++ & Blueprints) with 3+ years of game development experience, 800+ hours delivered on Upwork, and a shipped online multiplayer game on Steam. I build gameplay systems, multiplayer/networking, UMG interfaces and PCG/editor tools, and I fix broken UE5 projects, including engine-upgrade issues (e.g. UE 5.3 to 5.5). Selected work: - CADVIX: UE5 kitchen configurator. I designed and built the UI/UX in UMG (menus, HUD, interaction flow) and implemented movement, cameras, and cabinet spawning/interaction logic. - VR World Builder: UE5 PCG procedural generation and spawning tools for a VR world-building project. - Arcane Fighters: 2D 4-player online PvP game released on Steam by my own studio. I built the core gameplay, 4-player networking, menus and HUD (Godot). - ZeppelinX: turn-based game in Godot, where I was the sole programmer. - A reusable UE5 multiplayer plugin. What I can help you with: - Gameplay systems in C++ and Blueprints - Multiplayer, replication and dedicated servers (AWS GameLift basics) - UI/UX design and implementation in UMG - Product configurators and interactive 3D apps - PCG and editor tools - UE version upgrades, bug fixing and cleanup of existing projects - Blender to UE5 asset pipeline and Perforce/Git setup Background: I founded and led an indie studio (Sleeping Unicorn Studios) and previously worked as an electrical engineer at ABB, so I work in a structured way, document what I do, and communicate clearly. Based in Czechia (CET), flexible with US and Asian time zones. Tools: Unreal Engine 5, Godot, Rider, Visual Studio, Perforce, Git, Jira, Trello. Send me your project or bug list and I'll reply with a concrete plan and estimate.
