Confidential 3D Web Platform Development

Title: Technical Selection: Senior Three.js/WebGL Developer for a Confidential Browser-Based 3D Platform Project Overview: We are selecting a highly qualified senior developer or technical lead for a confidential browser-based platform built around a premium, navigable 3D architectural environment. The full concept, business model, platform structure and architectural plans will be disclosed only to shortlisted candidates after signing confidentiality and intellectual-property agreements. The purpose of this listing is to evaluate technical capability, relevant experience and suitability for the project. Pricing is not being discussed at this stage. Project Requirements: * Premium architectural 3D environments running inside a web browser. * First-person or third-person navigation. * Desktop keyboard and mouse controls. * Mobile touch controls. * Collision detection and interactive entrances. * High-quality lighting, glass, materials and environmental details. * Arabic and English interface readiness. * Optimized performance across desktop and mobile devices. * User accounts, permissions, databases and administration systems. * Private deployment and client ownership of all project files. Required Technical Experience: * Three.js and WebGL. * React Three Fiber or Babylon.js. * React/Next.js and TypeScript. * Blender, Maya or an equivalent professional 3D workflow. * Architectural environment modelling. * GLB/glTF asset pipelines. * Draco/KTX2 compression. * LOD, instancing, texture optimization and baked lighting. * Collision, navigation and interactive scene development. * Full-stack authentication, databases, role-based permissions and administration dashboards. * Production deployment and performance monitoring. Application Requirements: 1. Provide a live link to at least one navigable architectural 3D environment running inside a browser. 2. Provide two additional live Three.js/WebGL projects. 3. Explain precisely which parts of each project you personally developed. 4. Provide a short screen recording demonstrating navigation and interaction in your strongest project. 5. Confirm the name and experience of the exact senior developer who will lead this project. 6. Confirm whether you personally create professional architectural 3D environments or work with a dedicated 3D environment artist. 7. Explain how you would optimize a large architectural environment for mid-range mobile devices. 8. State your recommended technology stack and explain why it is suitable. 9. Confirm that the same developer presented during selection will remain responsible for the project. 10. Confirm that all source code, repositories and original 3D files can remain in client-owned accounts from the beginning. Product configurators, rotating product models, static 3D renders and standard website animations are insufficient. Applications without a live navigable browser-based 3D environment will not be considered. Generic or automated proposals will be rejected. Begin your application with the words “PRIVATE 3D” to confirm that you have read the complete listing. Confidentiality and Ownership: Shortlisted candidates must sign confidentiality and intellectual-property agreements before receiving detailed project information. No project material may be published, copied, reused, demonstrated or included in a portfolio without written authorization. At this stage, selection will be based exclusively on proven technical experience, live work quality, architectural 3D capability and full-stack competence. Please do not include pricing in your initial response.
