Hire the Best Game Developers in New York

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, and Adobe/Harman AIR • Full stack development with Java EE and LAMP I have also helped resurrect or restore control over a number of JavaScript and Animate 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 aligned again. My projects have included: • A TV/Film production prop iPhone app to simulate calls, texting, and VFX screens (AIR, Flutter) • JavaScript games for TV/Entertainment using CreateJS/EaselJS (GSAP) and ZIM (HTML5 Canvas) • The re-architecture and substantial coding and rework of a medical training program (JS) • The addition of key features to a StoryLine 360 product (PDF printing via JS) • A self-publishing photo album service with mobile page design, image manipulation, painting and sticker functions. Required 3rd party REST integration with other commercial services (AIR) • Archery scoring application for iOS, ranked as high as #16 in the Sports category (AIR) If you have a JavaScript or Animate project that needs creation or work, it is likely that I can provide for you. Drop me a line and we’ll discuss what can be done.
