You need a Unity developer who actually ships — not someone who disappears after onboarding or ghosts you when things get hard.
I've built and delivered 26 Unity projects on Upwork with a 100% Job Success Score and Top Rated badge. My specialty is multiplayer games — using Photon Unity Networking (PUN) to build real-time, low-latency experiences for mobile and PC.
Here's what I bring to your project:
⚡ Multiplayer & Networking — PUN, real-time syncing, lobby systems, matchmaking
📱 Mobile Game Development — iOS & Android, optimized for performance and battery
🎮 Full Game Pipeline — from concept to Play Store / App Store submission
🛠️ Systems Design — combat systems, inventory, progression, economy, UI/UX
🌐 Cross-Platform — PC, mobile, console-ready builds
💰 Monetization — ads (AdMob, Unity Ads), in-app purchases, rewarded systems
I run a small dedicated studio. That means you get a senior developer leading your project AND a design team supporting it — without paying agency prices.
I take on projects where I can do my best work. If your scope is clear and you value quality communication, we'll work well together.
Let's build something players actually want to play.

I work with studios, startups, and founders building Unity games that need more than code — they need structure that keeps players playing.
My work isn’t about “just development.”
It’s about solving the problems that stop games from succeeding and building games around core gameplay loops, retention systems, and performance-ready architecture.
Games don’t collapse at launch because of graphics.
They collapse because:
• physics, camera, and input not tuned together .... killing game feel
• mechanics built in isolation, not as a loop
• update() logic doing too much per frame
• controls that feel “slightly off” but never fixed
• levels built without pacing logic
• bugs piling up because architecture wasn’t built to scale
• poor optimization....... performance not profiled early, leading to FPS drops on real devices
By the time this shows, retention is already dead.
That’s where I step in.
🎮 Game Systems I Build
• Unity 2D / 3D Game Development
• Unity Mobile Game Development
• Endless Runner & Hyper Casual Systems
• Level Design focused on player flow and difficulty balance
• Gameplay mechanics & player progression
• Retention and reward systems
⚙ Technical & Performance Work
• Low FPS fixes & performance optimization
• Fixing lag, crashes, and bugs
• Bug fixing, build errors, crash issues
• Mobile optimization (Android / iOS)
• Unity WebGL deployment
• Scalable C# architecture
🌐 Web3 / Blockchain Game Development
• Web3 & NFT game development
• Blockchain game systems
• Crypto game logic
• Discord-integrated game systems
I don’t build random mechanics.
I work best with teams serious about building something players actually stick with.
