3D Web Developer (Three.js / WebGL) for Interactive Web Experience

We need an experienced Three.js developer to build an interactive 3D web experience. You will optimize assets, build the scene, and implement user interactions like clicking, dragging, and animations. Must deliver 60fps on desktop and mobile. Strong 3D math and asset optimization skills required. Please include portfolio, timeline, and rate. QUESTIONS: 1. A scene with 50 animated characters drops to 20fps. Walk us through your step-by-step debugging and optimization process to get it back to 60fps. Include specific tools you would use. 2. A 3D artist gives you a 250MB glb file that loads slowly. What specific techniques and tools would you use to reduce file size by 80 percent while preserving visual quality? 3. Write a short Three.js code snippet that spawns a 3D object 5 units directly in front of the camera, based on the camera's current facing direction. INSTRUCTIONS: Answer all 3 questions in your proposal. Include your portfolio, estimated timeline, and rate. Applications without answers will not be reviewed.
