Vladyslav H.

Senior Unity Developer with 5+ years of experience delivering 15+ mobile, WebGL, and XR applications from concept to release. I build clean, well-structured gameplay systems that stay stable as projects grow. I focus on core systems and performance, so new features can be added without breaking what’s already working. WHAT I CAN HELP WITH • Gameplay systems - progression, UI, save/load, input • Multiplayer - Photon (PUN/Fusion), Netcode, matchmaking, session management • Cross-platform builds - iOS, Android, WebGL, Quest, Pico • Performance optimization - profiling & real device tuning (60+ FPS targets) • Custom editor tools - reducing repetitive setup time by ~60% • Backend integrations - Firebase, AWS, Unity Gaming Services WHAT YOU GET • Tested and optimized on target devices • Clean structure, so new features don’t break existing systems • Code that stays manageable as the project grows • Clear communication and realistic estimates • Organized Unity projects that other developers can easily work with SPECIALIZED EXPERIENCE Architecture & Systems Design I structure Unity projects so new features can be added without breaking existing systems. Clean setup from the start means fewer refactors later. Mobile & XR Performance Shipped 10+ VR apps (Quest/Pico) and optimized builds to maintain stable frame rates on target hardware, not just in the editor. Multiplayer & Online Features Integrated multiplayer functionality, authentication flows, and persistent data systems to keep sessions stable and player data reliable. UI & Game Systems Implementation Built scalable UI and gameplay systems that work consistently across different screen sizes, aspect ratios, and platforms. RESULTS • Delivered 15+ applications across mobile, WebGL, and XR • Shipped 10+ VR apps for Quest and Pico • Built real-time tracking and session systems used in production • Created internal tools that reduced content setup time by ~60% • Led core system and UI architecture on cross-functional teams COMMON PROJECT TYPES • “Add multiplayer to my game.” • “Improve performance on mobile/VR.” • “Fix project structure before adding more features.” • “Build core systems properly from the start.” • “Connect Unity to Firebase or other backend services.” • “Build a quick prototype to validate a game idea.” If you need structured Unity development with long-term stability and predictable delivery, feel free to reach out.
