Experience

I am a professional game developer since April 2015, beforehand I worked on many side projects.

I like to use the term "Generalist Programmer" when talking about myself because I enjoy working on many aspects of game projects - from game engines to the tiniest visual elements. Thanks to my deep understanding of the tech I can implement the gameplay mechanics or other higher-level elements in the most efficient way.

Platforms

• Windows (Steam) - 32/64bit
• Linux
• Mac OS X
• Nintendo Switch
• Play Station 4 (Pro)
• Play Station 5
• Xbox One S/X
• Xbox Series S/X

Game engines

• Ray - TruckersMP proprietary framework (Windows)
• prism3d - SCS Software proprietary game engine (Windows, Linux, MacOSX, Steam)
• RED ENGINE - CD PROJEKT RED's proprietary game engine (PC, Play Station 4, Xbox One, Steam)
• Unity Engine - (PC, Nintendo Switch, Play Station 4, Xbox One, Steam)
• Unreal Engine - (PC, Play Station 5, Xbox Series X/S, Steam)

Main Technical Achievements

• Created initial version of framework used to build multiplayer modification for already released computer game using C++ and RakNet for networking.
• Reverse Engineering of commercial games to understand them and implement multiplayer modification.
• I've initiated and led the adoption of the C++11 standard into the SCS Software codebase.
• Implemented highly-performant std::function style functor class with fixed size storage compliant with C++11 standard.
• Optimized LOUD My Road To Fame rendering to work at an average of 60 FPS on Nintendo Switch Handheld mode.
• Designed multi-platform framework (Game saves, Achievements, User management, DLC) in C# that passed certification on Nintendo Switch, Play Station 4, and Xbox One - (PC, Play Station 4, and Switch implementation backends were done by me).
• Worked together with engine developers on improving toolset for the optimizing streaming subsystems.
• Implemented camera system for vehicles.
• Designed and implemented a fully-fledged modern multiplayer framework with snapshots/delta compression optimization in C# 100% based on the reflection system.
