Hammad S.

Give me a game to build and I'll deliver it working, tested, and ready to ship. I am a Unity mobile game developer, also specializing in Photon multiplayer and Meta Quest VR and AR, all built in C#. You get complete playable builds for Android and iOS, not half finished prototypes. Whether you need a mobile 2D or 3D title that runs smoothly on low end Android devices, a Photon multiplayer game, or a Meta Quest VR experience, I take it from concept to a build you can actually publish. WHAT I BUILD - Mobile 2D and 3D games for Android and iOS, optimized for low end hardware - Online multiplayer games and real time systems using Photon PUN and Fusion - VR experiences for Meta Quest using the XR Interaction Toolkit - Complete game loops including core mechanics, progression, upgrade economies, UI and save systems - Fixes and upgrades to existing Unity projects, including performance profiling and new features - AI and LLM integration inside gameplay for dynamic scoring and NPC behaviour SELECTED WORK - VRSim, a multiplayer VR courtroom simulator built on Photon networking with LLM based argument scoring - Cross Fire, a 3D FPS with a complete story mode - Car Crash, a 3D mobile racing game with a full game loop - Jimmy the Runner, a 3D endless runner - Client games delivered through Upwork including a Pac Man style 2D arcade game, a voice command battle game with speech to text and AI driven combat, and an educational quiz game GAME TYPES I SPECIALIZE IN - Mobile hyper casual, endless runner and racing games - First person and third person shooters - Multiplayer and co op games - VR simulation and training environments - Educational and serious games - Prototypes and MVPs for pitching or funding TECH I WORK WITH - Unity & C# - Photon PUN and Fusion - Mirror - XR Interaction Toolkit - Meta Quest SDK - URP, Shader Graph - Cinemachine and Timeline - NavMesh and A* Pathfinding - Scriptable Objects and custom editor tools - Addressables, Unity Profiler - Firebase and PlayFab - Unity Ads and IAP - Blender - Git SKILLS Unity, Unity3D, C#, Game Development, Mobile Game Development, Mobile Game, Android, iOS, Photon Unity Networking, Photon PUN, Photon Fusion, Online Multiplayer, Multiplayer, Virtual Reality, VR, Meta Quest, XR Interaction Toolkit, AR & VR Development, Augmented Reality, Game Design, Game Prototype, Game Development Bug Fix, Game Customization, Game Consultation, Performance Optimization HOW I WORK We start with a short call to pin down the game idea, the target platform and what success looks like. Before I write a line of code you get a clear scope and milestone plan, so there are no surprises on cost or timeline. I schedule calls around your time zone, so arranging one never takes three days of back and forth. Slack, Discord, Zoom or Google Meet, whichever your team already uses. At every milestone you get a build you can actually play, not a status update. That means you are never guessing about progress and you can redirect the design early instead of after it is expensive. I reply within a few hours and I flag problems as soon as I see them. When the game is done I handle the build settings, store readiness and testing across devices, then walk you through updating content yourself so you are not locked into me for every small change.
