Multiplayer desyncs. Frame drops under load. Hardware that won't stay in sync. If that's the wall you've hit, you need a UE5 developer who thinks in systems, not just Blueprints. I'm a C++ engineer building high-performance Unreal Engine 5 applications and custom modules for teams that need stability, consistent frame rates, and reliable hardware integration. What I bring that a standard UE dev doesn't: Low-Level Performance & Thread Safety — custom memory allocators, lock-free structures, zero tolerance for dropped frames under load. Real-Time Systems & Hardware Sync — 1+ year (NDA) architecting real-time C++ logic for multi-display hardware devices and microcontrollers. Custom Engine Plugins & Protocols — raw UDP voice pipelines, OpenCV computer vision integration, encrypted binary serialization for multiplayer. Core focus: ✓ UE5 gameplay & network replication (C++ / Blueprints) ✓ Profiling & performance optimization (memory pools, CPU/RAM budgets) ✓ Custom C++ engine plugins & Win32 integration ✓ VR / interactive real-time applications If your project needs to hold up on real hardware under heavy load, let's talk about what you're building.

Hi, my name is Arsen. I’m a Senior C++ and Python developer with 5+ years of experience building software for Linux, Windows, and embedded systems. I focus on clean, efficient, and reliable solutions for low level, backend, and performance critical tasks. What I bring to projects: • C/C++ development: STL, Boost, Boost ASIO, Qt, WinAPI, OCCI, V8, POSIX, multithreading • Python development: automation tools, data pipelines, backend logic, Django • Database engineering: Oracle, SQLite, MongoDB, data export tools, batch processing, custom type conversion • Linux systems programming: networking utilities, driver level interaction, Linux kernel headers, OpenWRT, desktop and CLI tools • Wireless and low level networking: Generic Netlink, nl80211, libnl/libmnl, Wi Fi scanning tools, protocol and frame parsing • Reliability and performance: profiling, transactional workflows, data integrity focused design, Dockerized builds, CI/CD with TeamCity • Cross platform delivery: Linux and Windows applications, Make, CMake, Conan, Git/SVN, GDB, Valgrind, Doxygen, Bash I have built tools ranging from high performance Wi Fi scanners in C that interact directly with the Linux wireless stack, to cross platform C++ command line utilities that export Oracle data into SQLite with transactional safety and performance profiling. I am comfortable working close to the system, optimizing throughput, handling large datasets, and designing software that is maintainable and stable in production. Clients usually trust me with complex backend, systems, and infrastructure related tasks where performance, correctness, and long term reliability matter. If you are looking for a developer who can work on C++, Python, Linux internals, networking, or data heavy applications, let’s talk. 🙂

As a passionate developer with a strong foundation in multiple programming languages and engines, I have dedicated the past few years to mastering C++, C#, and Python. My journey began with learning C++ for over two years, during which I developed multiple games from scratch including projects such as Doodle Jump, Breakout, and a Doom (1993)-like game. Additionally, I created my own graphics engine using DirectX, demonstrating my expertise in computer graphics, CPU-GPU synchronization, and performance optimization. My experience spans both Unreal Engine and Unity, where I have designed and implemented games ranging from immersive VR titles for the Meta Quest platform to complex RPGs and shooters. In Unreal Engine, I have worked extensively on optimizing rendering pipelines, ensuring high performance without compromising visual fidelity, and enhancing shaders to achieve more efficient real-time rendering solutions. During my rendering internship, I specialized in real-time rendering, shader creation, Ray Tracing, and Physically Based Rendering (PBR) using DirectX. Furthermore, my contributions to the open-source Life Engine helped me enhance my proficiency in Vulkan and shader development. Through freelance projects, I have developed strong teamwork and communication skills, enabling me to seamlessly integrate into diverse teams, adapt to existing codebases, and meet tight deadlines. Passionate about video games and their potential to inspire and entertain, I bring both technical expertise and creative vision to every project.
