I build games that are fun to play, technically solid, and ready to scale. Over the past 6+ years, I've developed 20+ games across Unity, Unreal Engine, Roblox, and Godot for Mobile, PC, WebGL, AR/VR, Multiplayer, Metaverse, and Web3 platforms, from rapid MVPs to polished commercial releases used by thousands of players. Most clients come to me in one of two situations: You have a game idea and need an experienced developer to turn it into a polished, scalable product, with the right architecture, optimized performance, and gameplay that keeps players engaged. You already have a game that's incomplete, buggy, poorly optimized, or missing key features , and need someone who can quickly understand the project, improve the codebase, and deliver without disrupting development. I'm equally comfortable with both. What I do end-to-end: > Full-cycle game development in Unity, Unreal Engine, Roblox Studio, and Godot > Multiplayer game development using Photon Fusion, Photon PUN, Mirror, FishNet, Netcode for GameObjects, and Epic Online Services > Mobile, PC, WebGL, Console-ready, and Cross-platform game development > Gameplay programming, AI systems, combat mechanics, inventory, quests, progression, and save systems > AR/VR, XR, Meta Quest, OpenXR, WebXR, and mixed reality experiences > UI/UX implementation, animations, VFX, shaders, and game optimization > Backend integration using PlayFab, Firebase, REST APIs, Node.js, and cloud services > LiveOps features including leaderboards, achievements, matchmaking, analytics, cloud saves, and in-app purchases > Performance optimization, bug fixing, profiling, and publishing to Google Play, App Store, Steam, Meta Quest, and Roblox What working with me is actually like: I communicate like a partner, not just another freelancer. You'll always know the project's progress and next steps. I ask the right technical questions before development starts, helping avoid costly redesigns and unnecessary delays. I deliver milestones on time, and if there's ever a challenge, I communicate it early with practical solutions. I write clean, modular, and maintainable code that's easy to extend as your game grows. Featured Projects Critical Ops - Multiplayer FPS Contributed to a fast-paced multiplayer FPS featuring real-time matchmaking, competitive gameplay, responsive controls, weapon systems, and mobile performance optimization. BitFreaks - Multiplayer Game Developed online multiplayer gameplay with scalable backend integration, player progression systems, and real-time social interactions.

Share your game concept or your current development challenges, and I'll give you an honest assessment of the best way to move forward.

I help startups, brands, and businesses build immersive, interactive digital experiences using Unity. If you're looking to create more than just an app — if you need engagement, interactivity, gamification, or simulation — I can help turn your concept into a scalable, production-ready product. 🚀 What I Build ✔ AR applications (AR Foundation – marker & markerless) ✔ VR experiences (Meta Quest, immersive simulations) ✔ Gamified mobile apps (education, fitness, training, kids learning) ✔ Interactive simulations & training tools ✔ Product configurators & visualizers ✔ 2D & 3D Unity applications ✔ MVP development for startups ✔ Android, iOS & WebGL deployment 🎯 Who I Work With • Startups building interactive MVPs • Businesses creating training simulations • Brands developing AR product demos • Agencies needing reliable Unity expertise • Founders looking to gamify their app idea 💡 Why Clients Work With Me - Strong Unity architecture & clean code structure - Focus on core engagement loop - Clear milestone planning & communication - Stable builds optimized for performance - Long-term collaboration mindset I don’t just develop features — I help shape ideas into products users actually enjoy using. 🌐 Multi-Engine Experience In addition to Unity, I’ve also developed projects using: • Roblox (multiplayer & UGC-style experiences) • Cocos Creator (2D mobile games) • Matter.js (browser-based physics games & simulations) This allows me to recommend the right technology based on your goals — not just push one engine. 🛠 Tech Stack Unity (2D/3D) AR Foundation Meta Quest VR C# Firebase REST APIs Multiplayer basics Animation systems Ads & In-App Purchases integration 📦 My Process - Understand your product goal - Define the interactive core loop - Build a stable MVP - Iterate based on feedback - Prepare for scale & launch If you're planning to build: • An AR product visualizer • A VR training experience • A gamified learning app • An interactive simulation • Or a scalable Unity-based MVP Let’s discuss your idea.
