Hi, I'm Danylo Golosov

Software Engineer | Unity Developer | AR/VR Specialist

Based in Berlin, Germany

What I Do

  • Software Engineering — Designing scalable server-side architecture and translating business requirements into backend systems. Built an authoritative game server in Rust from scratch, handling client-server communication, state validation, and concurrent connections. Check this project out under this link
  • Backend & Microservices — designing distributed systems, RESTful APIs, and event-driven architectures (Java Spring, Python Fast API, AWS Services)
  • Systems Engineering — low-level networking, concurrency, and performance optimization (Rust, C++)
  • Full-Stack Development — end-to-end features from database schema to UI, using Vue.js, React, and TypeScript
  • DevOps & CI/CD — containerized deployments with Docker, automated pipelines with Jenkins, release ownership across multiple production apps
  • AR/VR Development — Building cross-platform AR applications with AR Foundation, ARKit, ARCore, XR Interaction Toolkit, and OpenXR. Shipped 10+ AR projects at ZAUBAR, including haptic feedback integration for VR.
  • Game Development — Creating games in Unity with a focus on clean architecture, state machines, and multiplayer networking. Built a fully authoritative Rust game server supporting 200+ concurrent players.

Featured Projects

Rust Multiplayer Game (Paper.io 2 Clone)

A 3D multiplayer territory-capture game with an authoritative Rust server supporting 200+ concurrent players. Full client-server communication pipeline with server-side game state validation to prevent cheating. Built with Unity URP, Protobuf/WebSocket networking, and procedural mesh rendering.

Repos: Unity Client · Rust Server

Solar System Simulation

A physics-accurate 3D solar system simulation built from scratch using C++17 and OpenGL 3.3. Custom rendering engine with modular architecture, custom shaders, camera systems, and scene management — no game engine used.

VR Tower Defense

A VR tower defense game built in Unity with XR Interaction Toolkit, featuring spatial tower placement and real-time enemy pathing. Tower AI uses a state machine architecture for clean, extensible combat logic.

Parallax (Bachelor Thesis)

A 4X strategy game developed in Unity as a bachelor thesis project at Lublin University of Technology, showcasing complex game systems and custom shader work.
