I build games that are fun to play, technically solid, and built to grow. Over the past 4+ years, I've developed 20+ games across Unity, Unreal Engine, Roblox, Godot, and Cocos2D for Mobile, PC, WebGL, Steam, and multiplayer platforms. From rapid MVPs to polished commercial releases, my focus is always on delivering games that perform well, engage players, and are easy to scale as they evolve.
Most clients come to me in one of two situations:
You have a game idea and need an experienced developer who can turn it into a polished, market-ready product with the right architecture, engaging gameplay, and optimized performance.
Or you already have a game that's incomplete, difficult to maintain, suffering from performance issues, or missing key features, and need someone who can quickly understand the project, improve the codebase, and keep development moving without unnecessary delays.
I'm equally comfortable with both.
What I do end-to-end:
Full-cycle game development using Unity, Unreal Engine, Roblox Studio, Godot, and Cocos2D
2D, 3D, Mobile, PC, WebGL, Steam-ready, and cross-platform game development
Multiplayer game development using Photon Fusion, Photon PUN, Mirror, FishNet, Netcode for GameObjects, and Epic Online Services
Gameplay programming, AI systems, combat mechanics, player controllers, inventory, quests, progression, save systems, and custom game mechanics
UI/UX implementation, animations, VFX, shaders, and responsive game interfaces
Backend integration using PlayFab, Firebase, REST APIs, Node.js, and cloud services
LiveOps features including leaderboards, matchmaking, achievements, analytics, cloud saves, in-app purchases, rewarded ads, and monetization systems
Performance optimization, bug fixing, profiling, memory optimization, and platform-specific tuning
Publishing and deployment to Google Play, App Store, Steam, Roblox, and WebGL
What working with me is actually like:
I work as a development partner, not just someone who writes code. You'll always know what's been completed, what's being worked on, and what comes next.
Before writing a single line of code, I ask the right technical questions to make sure the project is built on a solid foundation. That helps avoid expensive redesigns and saves time as development progresses.
I deliver milestones on schedule, communicate challenges early, and focus on practical solutions that keep the project moving.
Most importantly, I write clean, modular, and maintainable code that's easy to expand as new features are added.
Featured Projects
Critical Ops – Multiplayer FPS
Contributed to a fast-paced multiplayer shooter featuring real-time matchmaking, responsive controls, weapon systems, competitive gameplay, and mobile performance optimization.
BitFreaks – Multiplayer Game
Developed multiplayer gameplay with scalable backend integration, player progression systems, social features, and real-time networking.
Roblox PvP Experience
Built an engaging Roblox multiplayer game featuring custom combat mechanics, progression systems, monetization features, and optimized Lua scripting.

Developed strategy gameplay focused on resource management, base building, unit progression, AI systems, and long-term player engagement.
Poker Elephant – Online Card Game
Built an online multiplayer card game with matchmaking, smooth gameplay, intuitive UI, secure game logic, and engaging progression systems.
Hyper Casual Mobile Games
Delivered multiple hyper-casual titles featuring addictive gameplay loops, rewarded ads, in-app purchases, optimized performance, and strong player retention mechanics.
If you're looking for a developer who thinks beyond writing code and focuses on building games that are engaging, scalable, and commercially successful, let's talk. Whether you're creating a new game from scratch, expanding an existing title, or bringing a prototype to launch, I'll help you choose the right technical approach and build a game that's ready for players and built for long-term success.
