Hire the Best WebGL Developers
in Japan

I help clients turn game ideas, prototypes, and existing Unity projects into playable, reliable systems that can be tested, improved, shipped, and maintained. My main focus is Unity development: gameplay programming, UI-driven game loops, mobile/WebGL builds, scoring systems, progression, player interactions, content workflows, and production features. I work especially well on projects that need more than just code implementation: I can help structure the gameplay flow, identify missing requirements, improve usability, and make sure the system is practical to maintain after delivery. What I can help with: • Gameplay systems, interactions, and core game loops • Playable prototypes, MVPs, and vertical slices • Improving or completing existing Unity projects • UI, menus, scoring, timers, progression, feedback, and game flow • Mobile, WebGL, desktop, and browser builds • Data-driven content using JSON/CSV • Custom tools to make content easier to update • Bug fixing, polish, project cleanup, and stability improvements • External service/API integration when needed I also have experience with Unreal Engine 5, Godot 4, Construct 3, Blender, Git, and general production workflows, so I can communicate well across technical, design, and asset-related parts of a project. My Upwork history includes shipped mobile games, Unity ports, long-term production work, WebGL builds, prototypes, gameplay systems, and production support across desktop, mobile, and browser platforms. I work best with clients who want a practical developer who can think through both the technical implementation and the game design direction.

I build React + Three.js/WebGL interfaces for products that need more than standard forms and buttons: 3D product configurators, interactive dashboards, browser-based demos, WebAudio tools, and rapid MVP prototypes. My strongest fit is when you already have an idea, backend, design, or product flow and need a working frontend version fast. What I can help with: • 3D product configurators with real-time options, pricing logic, materials, lighting, and interactive previews • React / Next.js dashboards, admin panels, and frontend interfaces for existing backends • Three.js / React Three Fiber scenes, WebGL performance fixes, and browser-based 3D tools • WebAudio players, visualizers, and interactive audio interfaces • Fast MVP / proof-of-concept builds using React, TypeScript, Three.js, APIs, and AI integrations Recent relevant work: • Built an interactive 3D e-commerce configurator with dynamic pricing, UI tooltips, material options, WebAudio previews, and live quote sharing • Delivered browser-based interactive tools using React, Three.js, WebGL, WebAudio, and API integrations • Worked on touchscreen kiosk apps, educational simulations, and custom frontend prototypes I focus on practical delivery: clear scope, fast first working version, clean frontend structure, and small milestones that let you verify progress early. Best projects for me: • “I need a working prototype fast” • “I have a backend/design but need the frontend built” • “I need a 3D product viewer/configurator” • “My React/WebGL interface is unfinished, slow, or messy” • “I need an interactive demo before investing in a full product”
