VR Training Platform Development for Regulated Industries Riken helped us build the Phase 1 foundation of our Unity VR training platform (LRT Brain) targeting Meta Quest and desktop environments.

He delivered a reusable architecture with XR Interaction Toolkit, modular interaction systems, data-driven task logic, and a clean project structure that allows our team to extend the platform for future training modules.

Riken was responsive, cooperative during validation and debugging, and provided the final repository, documentation, and builds required for handoff.

Overall a good collaboration and a solid technical foundation for our platform. I would recommend Riken for Unity / VR development projects.

Surat, Indiaย - 1:51 am local time
Need a top game developer who actually delivers? You're in the right place.

I'm a senior unity developer and unity 3d developer with 9+ years in unity software development and unity video game development. I've built over 150 games and interactive apps. 75+ of those projects were completed right here on Upwork โ€” all with a 100% Job Success score and zero disputes. Mobile games, PC games, VR experiences, AR apps, multiplayer systems โ€” I've shipped them all.

Clients hire me for two reasons: I write clean code and I communicate clearly. No ghosting, no surprises, no messy handoffs. You get daily updates, fast responses, and a game that works exactly how you need it to.

Whether you want to hire a unity game developer or need complete unity game development services โ€” I deliver.


๐ŸŽฏ What I Build:

๐Ÿ“ฑ Mobile Game Development (iOS & Android)
Complete game development using unity from concept to cross-platform publishing. Gameplay, UI/UX implementation, animations, particle effects, and polished interfaces. I optimize for performance so your mobile game runs smooth on lower-end devices. Unity 2d game development and unity 3d game development โ€” I handle both.

I integrate monetization systems including AdMob, Unity Ads, AppLovin, and IronSource. In-App Purchases with server-side validation. Firebase Analytics and GameAnalytics connected from day one.

๐Ÿ–ฅ๏ธ PC & Video Game Development (Steam, Windows, Mac, Linux)
Full Steamworks SDK integration โ€” achievements, cloud saves, leaderboards, matchmaking, and overlay. URP and HDRP rendering pipelines, shader programming and visual effects for a professional look.

๐Ÿฅฝ VR Game Development (Meta Quest, SteamVR, HTC Vive)
Dedicated vr ar developer and meta quest developer. Vr game development unity and virtual reality game development โ€” XR Interaction Toolkit, hand tracking, grab mechanics, teleportation, spatial audio, haptic feedback. I build immersive interactions that feel natural. Vr application development and vr app development for standalone and PCVR, 90fps optimization where every draw call counts. Virtual reality software development for training, simulation, and real-time 3D visualization.

๐Ÿ“ฒ AR App Development (ARCore, ARKit)
Experienced ar developer for ar app development and ar mobile app development. I build augmented reality apps for product visualization, interactive marketing, and education. Surface detection, object placement, image tracking, face tracking. I deliver ar vr app development services, augmented reality app development services, and ar development services for businesses across retail, real estate, healthcare, and education.

๐ŸŒ Multiplayer Game Development
Online multiplayer using Photon (PUN2/Fusion), Mirror, Netcode for GameObjects, and custom WebSocket backends. Lobbies, matchmaking, chat, state sync, client-side prediction, lag compensation. Multiplatform game development that works reliably at scale.

๐ŸŒ WebGL & Browser Games
WebGL game developer โ€” browser-based games optimized for smooth gameplay without plugins.


โšก Where I Stand Out:

โšก Performance Optimization
My strongest skill. Unity Profiler, Memory Profiler, Frame Debugger, GPU Profiler. I fix overdraw, optimize shaders, implement object pooling, reduce draw calls, and eliminate GC pressure. Games from unplayable to smooth 60fps with documented results.

๐Ÿ”ง Bug Fixing & Project Rescue
Many clients hire me after a bad experience. I read unfamiliar codebases quickly, fix critical bugs, and clean up architecture so your project has a future.

๐Ÿ› ๏ธ Custom Game Systems
Inventory, save/load, character controllers, dialogue systems, AI behavior trees, state machines, level editors, and custom editor tools. Full c# game development โ€” reusable modules your team can maintain.

โ˜๏ธ Backend Integration
Firebase, PlayFab, or custom REST APIs for authentication, cloud saves, leaderboards, push notifications, remote config, A/B testing, and IAP validation.


โญ What Clients Say:
"Highly understanding with feedback. Works in a timely fashion. Great work!" โ€” Epoxy Studios, Canada
"Fantastic developer. We'll use him again for future projects!" โ€” Random Logic Games, US
"Very professional. Will definitely collaborate again." โ€” Kob Games

๐ŸŽฎ Games Built: Hyper-casual, puzzle, RPG, action, simulation, educational, endless runner, card, board, trivia, tower defense, racing, sports, fighting, idle/clicker, match-3, platformer, survival, horror, sandbox

๐Ÿข Industries: Gaming studios, EdTech, healthcare, real estate (AR), retail (AR product viz), entertainment, fitness, training/simulation, marketing agencies
