Greetings! I am a 3D Web Developer and graphics engineer (🔥 among the Top 1% of developers on Upwork 🔥) with over 10,000 hours of expertise. My focus is on creating high-performance, immersive applications. Whether you need a WebGL Three.js interactive experience or a cutting-edge WebGPU engine, I bridge the gap between desktop-grade graphics and the browser.
🚀 𝐓𝐡𝐞 𝐒𝐲𝐧𝐞𝐫𝐠𝐲 𝐨𝐟 𝟑𝐃 𝐖𝐞𝐛 & 𝐆𝐚𝐦𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭
As a senior 3D Web Developer, I don't just build sites; I engineer complex ecosystems. For the past 7 years, I have been actively programming game servers. This deep experience in Multiplayer allows me to handle complex networking tasks like rollback, snapshots, and state sync. Recently, I spent 2 years building a web-based game platform with a custom ECS, where I was responsible for WebGPU integration and a custom WebTransport server protocol. This background as a C++ Game Developer ensures that every WebGL Three.js project I touch is optimized at a systems level.
🛠 𝐌𝐚𝐬𝐭𝐞𝐫𝐲 𝐢𝐧 𝐖𝐞𝐛𝐆𝐋 𝐓𝐡𝐫𝐞𝐞.𝐣𝐬 & 𝐖𝐞𝐛𝐆𝐏𝐔
In the realm of a 3D Web Developer, performance is everything. I leverage WebGPU to push the limits of modern browsers, utilizing WGSL and GLSL for custom pipelines.
◾WebGL Three.js: I create stunning 3D product rendering, photorealistic 3D animation, and interactive 3D design.
◾WebGPU: Expertise in render bundles, compute shaders, and advanced Web application architecture.
◾React & Next.js Ecosystem: I specialize in React Three Fiber (R3F) to integrate WebGL Three.js into modern, scalable applications. As a front end developer, I ensure seamless state management and high-speed delivery for every Web application.
🎮 𝐌𝐮𝐥𝐭𝐢𝐩𝐥𝐚𝐲𝐞𝐫 & 𝐂++ 𝐆𝐚𝐦𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞
My journey as a C++ Game Developer covers large-scale desktop application and standalone application development. I understand the needs of an Xbox developer or a video game studio. As a Multiplayer specialist, I focus on:
◾Game Networking: Implementing Online multiplayer game design with high-performance protocols.
◾Engine Tech: Working with Babylon and custom C++ frameworks.
◾Multi-Platform: Bringing Multiplayer logic to mobile game environments (iOS/Android).
💎 𝐀𝐝𝐯𝐚𝐧𝐜𝐞𝐝 𝐆𝐫𝐚𝐩𝐡𝐢𝐜𝐬 & 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐚𝐭𝐢𝐨𝐧
An elite 3D Web Developer must master the math behind the pixels. Using Vectors, Quaternions, and Matrices, I implement:
◾Rendering: PBR, Shadow mapping, Ray tracing, and Path tracing.
◾Optimization: LOD, Spatial acceleration structures (BVH, Octree), and GPU Instancing.
◾Geometry: 3D modeling in Blender, Autodesk 3ds Max, or Maya, and procedural generation.
🤝 𝐖𝐡𝐲 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 𝐌𝐞?
Being both a C++ Game Developer and a 3D Web Developer means I offer architectural certainty. Whether I’m collaborating with a Python developer on high-performance backends or assisting a Unity web developer team with complex graphics, I solve the hardest tasks. If you are looking for a Multiplayer expert to build a mobile app development hit or a WebGPU pioneer for a technical Web application – let’s chat.
I provide the same level of care whether I'm acting as a graphic design consultant for 3D modeling or as a lead C++ Game Developer. As an Expert-Vetted talent, I offer free consultations to ensure we are an excellent fit. Let's bring your WebGL Three.js vision to life with Multiplayer capabilities that scale.
