Sergey Zabrodin

I’m a .NET Backend Developer with 4+ years of commercial experience building high-load, real-time distributed systems, including multiplayer and MMO backend services. I focus on scalable backend architecture, state synchronization, and data consistency across distributed environments, with a strong foundation in performance-critical engineering.

In my recent work at TirexArena LLC, I developed multiplayer MMO backend services using ASP.NET Core, designing and maintaining REST APIs for client–server communication. I built and optimized data storage with PostgreSQL, MongoDB, and SQLite, then ensured real-time synchronization of game state across multiple clients—improving performance and stability under concurrent multiplayer load. I also contributed to backend architecture and feature design decisions.

Previously at Nova Games LLC, I worked on multiplayer and turn-based systems, implementing networking and client–server interaction, and supporting real-time state synchronization. Before that, as a Research Engineer at the Russian Federal Nuclear Center (VNIITF), I built software tools for process simulation and automation, working on mathematically intensive, performance-sensitive tasks—skills that still influence how I model systems and validate behavior.
