Vitalii N.

🎮 Unity developer with 8+ years in Unity and 11+ years in C#. I build and fix Unity games and apps for mobile (Android, iOS), WebGL and PC, including multiplayer and AR. If your Unity project needs a new feature, a fix or a stable release, I can help. You can hire me as a Unity game developer for a new game from a prototype to a release, as a Unity 3D developer for an existing Unity3D project that needs fixes or new features, or as a Unity C# developer for code that has to be cleaned up and kept working. 📌 Proof & numbers • As a Unity developer I have delivered 30+ Unity projects, from small freelance orders to apps released on the App Store and Google Play. • As a Senior Unity developer at OnlySpace (MegaMod) I built a modular core with 90% code reuse across 7+ products. • The MegaMod multiplayer I built on Photon PUN 2, then Fusion 1 and Fusion 2, holds stable 200+ CCU per server in WebGL. • Profiling and targeted fixes gave x3–x10 FPS, up to x10 faster loading and up to x5 lower battery use. • notAlone (Chuze), which I built from scratch as a Unity mobile game developer, was acquired by a larger studio after the MVP. • My own Unity puzzle game Ternary has 10,000+ organic downloads on Google Play and 100+ levels. • Since 2025 I work as a freelance Unity developer: ad and attribution SDKs, bug fixes in existing Unity games, a Unity and Flutter integration, a hex map system and an Android info kiosk app. 🟢 What I do • Unity game development: I build gameplay systems, UI and tools and take a game from a prototype to a stable build. • Multiplayer: as a Unity multiplayer developer I work with Photon Unity Networking (PUN 2), Photon Fusion and Unity Netcode on rooms, lobbies, chat, reconnection and sync issues. • WebGL: as a Unity WebGL developer I tune memory and load time for low-end devices and build Unity to JavaScript bridges, with Safari and iframe fixes. • Mobile: I ship Unity iOS and Android builds, set up TestFlight and help with signing and App Store Connect. • AR / VR: as a Unity AR developer I made Explore Montfaucon, a geolocated AR tour app on the App Store, with AR Foundation, ARCore Extensions, the Geospatial API and Mapbox. As a Unity VR developer I have built my own test apps for Meta Quest. • SDK integration: ads and in-app purchases (AdMob, Unity Ads, Unity IAP, Appodeal, AppLovin), analytics and attribution (Unity Firebase, Amplitude, AppsFlyer, Adjust) and Xsolla payments. I test every Unity SDK on a device before release. • Bug fixing and performance: I reproduce a bug, find the cause and fix it, and I profile CPU, memory and GPU before and after a change. • Code: clean Unity C# with dependency injection (Zenject, VContainer), state machines and custom Unity Editor tools, so the next Unity developer on the project can keep working with it. ⚡️ How I work • As your Unity developer I work in Git, split the work into milestones and send a build with its version after each one. • I start with a quick review of the project and a plan with milestones, risks and next steps. • Short progress updates, and I say plainly what is done and what is left. 📩 To start with me as your Unity developer, send me your platform, what you have now (an idea, a prototype or a build) and the main goal. I'll look at it and tell you the next step and what I need from you.
