Hire the Best Unity Developers
in Thailand

Welcome to my profile! I’m a Unity Game Developer with hands-on experience building gameplay systems, prototypes and polished game features for PC and mobile games. Since 2019, I’ve worked on 20+ Unity games published on Steam, Google Play and itch io. On Upwork, I’m a Top Rated Plus freelancer with 100% Job Success and I help clients move from idea to playable build quickly and reliably. What I can help you with: • Gameplay programming and core mechanics • Unity game development in C# • Prototypes and vertical slices • Bug fixing and polishing existing projects • 2D / 3D game development • Game design support and consulting • Lighting, post-processing and scene optimization • Level design implementation I also have experience leading small teams of developers and designers. I can coordinate production, set priorities, assign tasks, review implementation and help keep the team aligned to deliver milestones smoothly and on schedule. Clients work with me when they need a developer who can join an existing project fast, communicate clearly and deliver stable results without unnecessary delays. If you need help with a prototype, gameplay feature, bug fixing or polishing a Unity project before release, I’m ready to help. - Roman

I'm a Unity C# developer with 8+ years of experience building games and interactive experiences that people actually play — over 1 million downloads across my titles, featured by YouTubers H2ODelirious and CaRtooNz with millions of combined subscribers. I've delivered projects professionally since 2023, including interactive installations and games for global brands like Pepsi, Honda, and Shiseido. I'm now focused on mobile game development for iOS and Android — from prototype to store launch. What I bring: Full-cycle mobile game development in Unity (concept, mechanics, UI, optimization, publishing) Clean, maintainable C# code built for performance on real devices Experience shipping products under real client deadlines and brand requirements 2x Norwegian Game Awards nominee I work best with indie studios, startups, and founders who have a game idea and need a reliable solo developer to own the technical execution end to end. If you need someone who has shipped real products with real players, let's talk.

I build and stabilize Unity multiplayer systems that actually hold up in production. I'm a seasoned software engineer and Unity developer specializing in networked gameplay, server-authoritative simulation, and physics-heavy multiplayer, with a track record of jumping into existing codebases, fixing hard issues fast, and shipping clean, maintainable improvements in C#. I've contributed to projects ranging from small prototypes to commercial titles, including Little Sim World and Nightclub Tycoon, which have collectively generated over $1M+ in revenue. What you can expect when working with me ✅ Production-grade multiplayer architecture (FishNet / Photon Fusion), clean replication and ownership models ✅ Server-authoritative movement & physics (tick-based simulation, reconciliation, smoothing, desync-proof gameplay) ✅ Prediction & responsiveness (client-side prediction where appropriate, input pipelines, snapshot handling) ✅ Hit detection & fairness (lag compensation strategies, interpolation/extrapolation, bandwidth-aware state sync) ✅ Fast, systematic debugging of desyncs, race conditions, "only happens online" bugs, and edge cases ✅ Performance-first netcode (GC discipline, CPU/bandwidth profiling, spawn/despawn churn, message frequency tuning) ✅ Clear communication, reliable execution, and practical decisions that keep scope under control Common ways I help clients ✅ Build multiplayer from an existing single-player prototype (or refactor netcode that's already in pain) ✅ Fix jitter, rubber-banding, input delay, desyncs, and authority/ownership bugs ✅ Implement networked abilities, projectiles, combat, interactions, and game loops without regressions ✅ Optimize replication, bandwidth, and CPU spikes; improve stability under real player counts ✅ Prepare multiplayer projects for release (QA fixes, platform readiness, edge cases, stress testing) If you need a Unity multiplayer specialist who can take ownership, move fast, and deliver server-authoritative, production-ready netcode - I'm ready to help. Additional strengths: gameplay systems, performance optimization, and physics-driven mechanics - especially when they must behave correctly online.
