About Quentin

What I do
I develop production-ready Unity features for mobile and indie studios: gameplay systems, virtual economy, backend integration, performance optimization, A/B testing.
Why choose me
I spent 3 years designing and shipping Virkalia, a mobile gacha RPG, as a founder of Luzash Entertainment. I touched everything that makes a mobile game that holds up in production: scalable Unity architecture, F2P economy, retention, SDK integration (analytics, ads, IAP), iOS/Android build pipeline.


Result for you: I don't just deliver code, I understand the product and business stakes behind every line. I know why a poorly designed inventory system kills day 7 retention.


Technical Stack
Engine: Unity 3D, C#, Addressables
Architecture: MVC/MVP, ScriptableObjects, typed events, dependency injection
Backend / LiveOps: PlayFab, Firebase, REST API, server-authoritative economies
Tooling: Git, Jenkins, Unity Cloud Build, Profiler, Memory Profiler
Platforms: iOS, Android (mobile focus)
Bonus fullstack web: React/Next.js, Node.js, WordPress — useful for internal tools, live ops dashboards, game websites

What I work on
→ Development of gameplay features (combat, progression, economy, meta)
→ Integration and debugging of third-party SDKs (analytics, ads, attribution, IAP)
→ Performance & build size optimization
→ Implementation of A/B testing and remote config systems
→ Taking over legacy Unity codebases (refactoring, technical debt)
→ Technical audits before scaling or fundraising
