Denis T.

10+ years building high-performance cross-platform solutions in Unity and full-stack web applications. Expert in scalable C# architecture, .NET backends, React frontends, and end-to-end development for games, simulations, tools, and interactive web products. I deliver clean, maintainable, production-ready code — from rapid prototypes to live multiplayer systems and enterprise web apps. Expertise: Unity & C# Development Gameplay systems, player controllers (FPS/TPS/2D/3D/physics), combat, AI (FSM/NavMesh), dialogue/inventory/quests, UI (uGUI/UI Toolkit), Shader Graph/VFX/post-processing. Multiplayer & Networking Photon (PUN/Fusion), Mirror, TNet — server-authoritative, rollback netcode, lobbies/matchmaking, custom TCP/UDP/WebSockets, PlayFab/Firebase integration. Mobile & Cross-Platform Android/iOS deployment, Unity IAP (consumables/subscriptions), AdMob/Unity Ads/IronSource, localization, push notifications, mobile optimization. WebGL & Web Applications WebGL performance tuning, responsive inputs/UI, Firebase (Auth/Firestore/Realtime), REST APIs, WebSockets, cloud saves, full-stack web apps with React frontends and .NET/C# backends. Full-Stack Web & .NET React.js (modern hooks/context/Redux), TypeScript, responsive design, .NET Core/ASP.NET APIs, authentication (JWT/OAuth), databases (SQL/NoSQL), CI/CD pipelines. XR (VR/AR) Meta Quest 2/3, OpenXR, hand tracking/passthrough, mixed reality, SteamVR, XR interaction/optimization. Tools & Optimization Custom Editor tools/ScriptableObjects, Addressables, asset pipelines, profiling (draw calls/GC/memory), object pooling, CI/CD (Unity Cloud Build). Additional Blockchain/Web3 integration (ERC-20/721, WalletConnect/MetaMask, NFT systems) when required. Track records: Mobile games (puzzle/arcade/racing/educational) Multiplayer competitive titles WebGL simulations/training tools VR/AR experiences (Quest) Internal Unity tooling Full-stack web applications (dashboards, interactive platforms, SaaS tools) Focused on stability, performance, scalability, and long-term maintainability. Tell me about your project — I'll architect and build it right from day one.
