I build interactive 3D web experiences with Three.js, React Three Fiber, and WebGL — backed by full-stack engineering that actually ships. I'm a full-stack engineer specializing in real-time 3D on the web. On the frontend, I build with React, Next.js, Three.js, and React Three Fiber — scene graphs, custom shaders, animation systems, camera/orbit controls, and state-driven UI, all tuned to run at 60fps in the browser. I don't just drop a model into a scene. I own the whole pipeline: 3D rendering and interaction on the frontend, asset prep and mesh processing in Blender (Python bpy API), and the backend, infra, and deploy underneath it (Node.js/FastAPI, Redis, Docker, AWS/GCP/Azure). What I work on: ✅ Three.js / React Three Fiber apps — configurators, 3D viewers, sculpting/painting tools, real-time avatars ✅ WebGL & shader work (GLSL), performance-tuned for 60fps in-browser ✅ Blender pipelines — mesh cleanup, voxel remeshing, texture baking, GLTF/GLB prep, headless automation ✅ Full-stack builds around the 3D layer — Node.js/Express/FastAPI APIs, Redis queues, MongoDB/MySQL, real-time data ✅ AI-integrated experiences — RAG, LLM streaming, async multi-model inference pipelines (OpenAI, Gemini) ✅ Cloud deploys — AWS (EC2, S3, CloudFront, Load Balancer), GCP, Azure, Docker/Kubernetes, CI/CD, NGINX Recent proof: - 3D sculpting & painting web app — sculpt, paint, and remesh .glb models in-browser, FastAPI + headless Blender backend - 3D house exterior configurator — real-time facade/roof/door customization, responsive, embedded live on a client site - UltronAI — real-time 3D avatar chatbot (STT→LLM→TTS), 67% latency cut, 100K+ req/day, Discord bot + NPM package - AskPDF — RAG document Q&A system with async pipeline and Redis-backed job queues Tech stack: Three.js · React Three Fiber · WebGL · GLSL · Blender (bpy, headless) · GLTF/GLB · React · Next.js · Node.js · FastAPI · Express · Redis · MongoDB · MySQL · AWS/GCP/Azure · Docker/Kubernetes Have a 3D concept, a configurator idea, or an existing WebGL project that needs performance work? Send me the details — happy to take a look.
