I have been building games and interactive experiences with Unity for over 9 years. In that time, I've shipped 120+ projects from quick mobile prototypes for early-stage startups to full-scale AR/VR applications for enterprises. What keeps clients coming back isn't just the code, it's that I actually care about whether the final product works and feels good to play. I have build Multiplayer Games, Casual Games, RPG Games, Board Games, Card Games, Stretegy Based Games, and many more....
𝗪𝗵𝗮𝘁 𝗜 𝗱𝗼:
𝟮𝗗 & 𝟯𝗗 𝗚𝗮𝗺𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
From flat, stylized 2D games to fully realized 3D worlds, I've built both. I handle scene composition, asset integration, lighting, and making sure everything looks and feels intentional, not just functional.
𝗖𝗵𝗮𝗿𝗮𝗰𝘁𝗲𝗿 𝗗𝗲𝘀𝗶𝗴𝗻 & 𝗔𝗻𝗶𝗺𝗮𝘁𝗶𝗼𝗻
I create and rig characters that actually move the way they should, with smooth transitions, responsive animations, and a personality that comes through in gameplay. Whether it's a simple 2D sprite or a full 3D character controller, I've got it covered.
𝗚𝗮𝗺𝗲 & 𝗔𝗽𝗽 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁
I build Unity projects with end-to-end gameplay mechanics, UI/UX, scene management, and everything in between. Clean C# code, proper architecture, and no spaghetti that breaks three months later.
𝗠𝗼𝗯𝗶𝗹𝗲 & 𝗖𝗿𝗼𝘀𝘀-𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺
iOS, Android, PC, I've shipped on all of them. I know the quirks of each platform and how to make your game run smoothly without surprise performance drops after launch.
𝗔𝗥/𝗩𝗥 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀
Using AR Foundation and Unity's XR toolkit, I've built immersive AR and VR apps across gaming, education, and simulation. If you have an idea that needs spatial computing, I've probably tackled something similar.
𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 & 𝗗𝗲𝗯𝘂𝗴𝗴𝗶𝗻𝗴
Got a Unity project that's lagging, crashing, or just feeling sluggish? I've improved frame rates, cut load times, and cleaned up inherited codebases more times than I can count.
𝗖𝗼𝗹𝗹𝗮𝗯𝗼𝗿𝗮𝘁𝗶𝗼𝗻 & 𝗟𝗼𝗻𝗴-𝗧𝗲𝗿𝗺 𝗦𝘂𝗽𝗽𝗼𝗿𝘁
I work well with designers, PMs, and other devs. I don't disappear after delivery, I stick around to make sure things actually work in production.
𝗔 𝗳𝗲𝘄 𝘁𝗵𝗶𝗻𝗴𝘀 𝗜'𝗺 𝗽𝗿𝗼𝘂𝗱 𝗼𝗳:
A mobile game I built crossed 5M+ downloads
Improved performance by 40% on a Unity app through targeted optimization
Shipped AR and multiplayer features across 35+ projects
Built Unity prototypes that helped two startups close their seed rounds
