Manish S.

I help clients turn game ideas into stable, polished, production-ready games that are built to be played by real users. With 13+ years of experience in game development and 60+ completed projects on Upwork, I’ve worked on a wide range of games across mobile, web, and desktop platforms, from casual and hyper-casual games to multiplayer, board, strategy, simulation, and live-service projects. A large part of my work involves taking an idea and turning it into a complete working product. This can include gameplay systems, UI/UX, animations, game logic, backend integration, monetization, optimization, testing, and final deployment. I work with both new projects and existing codebases where the goal is to fix problems, improve performance, add new features, or bring the game to production quality. I’m especially comfortable working with existing game projects. Many clients come to me with projects that are partially developed, have bugs, require new features, or need significant polishing before release. I first understand the existing architecture and gameplay flow, identify the actual problems, and then implement changes without unnecessarily disrupting the systems that are already working. On the development side, I have strong hands-on experience with Unity and C#, Cocos2d-x, Cocos Creator, Three.js, JavaScript/TypeScript, C++, and related technologies. Depending on the project, I work across Android, iOS, Web, and other platforms. I focus not only on getting a feature working, but also on making sure it performs reliably and remains maintainable as the project grows. I have experience building browser-based and web 3D experiences using Three.js and related technologies, including interactive 3D environments, gameplay systems, camera controls, animations, object interactions, and real-time multiplayer experiences. I’m comfortable working with existing Three.js projects as well as developing new web-based 3D functionality based on project requirements. I’ve worked on multiplayer and backend-connected games involving real-time communication, player synchronization, game sessions, APIs, databases, authentication, leaderboards, progression systems, and server-side integrations. I’m comfortable working on both the gameplay/client side and coordinating the technical requirements needed to connect a game with backend services. Gameplay and game feel are also an important part of my work. I can handle gameplay mechanics, player progression, missions, rewards, economies, inventory systems, AI/NPC behavior, level systems, animations, VFX, UI flows, and other systems that make a game feel complete rather than simply functional. I also have extensive experience with mobile game development and monetization, including AdMob, rewarded ads, interstitials, banner ads, in-app purchases, ad-removal systems, daily rewards, lives/energy systems, and other retention and monetization features. I’ve worked on projects through the development cycle up to testing, store preparation, and production release. For web games, I work with technologies such as Three.js, Cocos, JavaScript/TypeScript, PixiJS, and related web technologies. I’ve worked on browser-based games including Ludo, board games, casino/slot-style interfaces, promotional games, interactive experiences, and 3D web experiences where loading time, responsiveness, browser compatibility, and smooth gameplay are important. Game development is not limited to programming for my team. We also provide UI/UX, 2D/3D game art, character and environment assets, animation, Spine/Rive animation, VFX, and other production requirements when a project needs a complete development pipeline. One of my strengths is being able to work closely with clients and understand both the technical and product side of a game. You can come to me with a complete specification, an existing prototype, a game template, a design, or simply an idea, and I can help turn that into a structured development plan and a working product. I focus on clean implementation, practical solutions, clear communication, and long-term maintainability. I don’t believe in simply patching problems when the underlying system needs improvement. When I work on an existing project, my goal is to understand why something is failing and fix it properly so the same problem does not continue affecting future development. Whether you are starting a new game, improving an existing project, adding multiplayer, integrating backend services, building a 3D web experience with Three.js, polishing gameplay and UI, fixing bugs, or preparing a game for release, I can help take it from its current stage to a production-ready result. If you already have a game in development—or just an idea that you want to turn into a real game—feel free to share the details. I’m happy to review the requirements, understand what you’re trying to achieve, and suggest a practical way forward.
