3D Android Developer - 3D Avatar Rendering Optimization Test

I am targeting this rendering quality: https://drive.google.com/file/d/1d0sB_ID-Ita8YrDVFP3FdnQ-D_5ar8VB/view?usp=sharing We need an experienced Android developer to build a test app that renders a highly realistic 3D human avatar with smooth, natural animations — talking, smiling, and blinking. This is primarily an assessment of rendering optimization skills — the goal is to find a developer who can produce the best visual quality with the least resource usage. Key Details Render a realistic 3D avatar with natural skin tones, smooth shading, and lifelike motion Avatar should perform idle animations: talking, smiling, blinking, subtle head movements Drag-to-rotate to change viewing perspective ARKit 52 blendshape standard and rigged model are preferred A reference video will be provided showing the expected quality Target: smooth 60 FPS on mid-to-high-end Android devices Requirements Experience with 3D rendering on Android (Unity, Unreal, Filament, OpenGL ES, or similar) Proven work with realistic character rendering (skin shading, PBR materials) Experience with rigged character animation and blendshapes Portfolio or demo videos of realistic 3D characters on mobile Selection Criteria Candidates who deliver the highest visual quality with the lowest resource consumption (CPU/GPU usage, memory, battery) will be shortlisted to the next step. Deliverables Working APK + source code Short demo video on an actual Android device How to Apply Please share your relevant experience, portfolio/demo links, and recommended technical approach.
