Hire the Best Game Developers in New York

A three-year professional video game programmer with expertise in functional performance optimization, online issue management, bug docking with the engine department, and requirements. I am not good at 3D modeling or draw a picture, there will be a basic art which can be used commercially from me, so you may need to provide more art assets. My Skills: [Software Skills]: Unity3D Engine, Unreal4 Engine, RPG Maker, C#, Lua, Python, C++, Matlab Linux, XShell, PostgreSQL, MongoDB, Git, SVN [Art]: Photoshop, Aseprite, AI painting, Video editing(by CapCut) [Others]: Mind map, Excel, Word, PowerPoint, etc About the time of milestones, it's a roughly time, it may change cause it's my part-time job, I may have more time on this project, but I am sure at least I can complete the milestone before the time. About big additional system or level, let's say $50 each and 1 more week. About small adjustment, it's free to change or adjust every design before we start or in the mean time of the milestones, but if you want to change after the mile stones and you say ok about it, and if it may takes more than 20minutes, let's say $5 for each adjustment.

I help game teams and indie developers fix, build, and improve Unity/C# projects, including gameplay systems, multiplayer, backend integrations, PlayFab, debugging, and tools. I’m a senior C#/.NET and Unity developer with 10+ years of professional engineering experience. I’m also the founder and lead Unity developer of Race Jam, a shipped multiplayer Steam racing game with 10,000+ downloads. I’m strongest in projects where you need someone who can quickly understand an existing codebase, diagnose problems, and deliver clean, practical fixes. Best fit projects: • Unity/C# bug fixing • Gameplay systems • Unity Netcode / multiplayer issues • PlayFab leaderboard or backend integration • Unity editor tools • Prototype cleanup • Performance/debugging support • C#/.NET API or automation work Relevant experience: • Race Jam — a multiplayer Unity racing game released on Steam • Guavas — an iOS application built with Swift and AWS EC2 infrastructure • Built race systems including checkpoint validation, lap tracking, placement sorting, and race/session flow • Implemented online multiplayer using Unity Netcode • Integrated Azure PlayFab leaderboard functionality • Built production C#/.NET, SQL, AWS, and automation systems across 10+ years I’ve also hired and managed contractors myself, so I understand the client side of Upwork: clear scope, reliable communication, milestone-based delivery, and no surprises.

I have over 10 years of experience in Unity. I have developed 20 games so far ranging from turn based to online strategy with match making. I am experienced with Unity's event flow and have a firm grasp of the Structures and Idioms needed in Game Development. My expertise lies in multiplayer games with simple rules that yield complex interactions between users. It doesn't take me long to have a working prototype and my projects are mostly designed to work with mobile and various account systems like Steam, IOS and Google-Play. My recent project is a game called Chess Cubed which will be out on Steam and Android and IOS soon. The game was completed in 6 weeks and offers innovative game-play. This is blazing fast compared to other 3D chess variants that typically estimate 6-8 months of development time and leaves a lot more room for visual polish and Q&A. What more can I say? Apple Vision Pro developer MetaQuest developer. I also have experience in Pose recognition using Nuitrack and Azure Kinect.

Upwork Certified in JavaScript backend (Node.js) development. I am an experienced programmer of consumer facing applications and services, with a background building in the arts, publishing, and education industries. I have been designing, developing, and assisting with software projects in a number of categories • Web and game development with HTML5/JavaScript (CreateJS, ZIM) • Mobile development with Flutter/Dart • Full stack development with Java EE • Greenfield development and restoration of function/forensic analysis and correction using AI agents (Claude Opus and Fable) I have also helped resurrect or restore control over a number of Java and JavaScript projects. If you find yourself facing a deadline, or need assistance untangling a codebase, please get in touch and we can talk about how get things running again.
