Development of a real-time 3D viewer for CGTrader, the world's largest 3D model marketplace (12M users, partners Google, Canva, Amazon), as part of their AI model generation pipeline.

The viewer, built with Three.js, TypeScript, and React, allows inspection and validation of AI-generated 3D models with an advanced level of technical control: multiple rendering modes (PBR, Clay, Normals, Roughness, Metalness, Base Color), non-destructive wireframe overlay, full HDRI environment management (intensity, rotation, custom HDRIs), real-time topological statistics (faces, vertices, draw calls), and multi-format export (glTF/GLB, STL, OBJ, FBX, USDZ).

The architecture was designed modularly with a public API for model loading/unloading, rendering mode switching, and export, and a serializable state to facilitate future AI editing extensions.

Development of an interactive 3D viewer integrated into the Presti AI platform, a SaaS tool used by over 300 furniture brands to generate photorealistic product visuals using generative AI.

The mission involved designing and implementing a viewer that allows end customers to import 3D furniture into a scene, manage all transformations (position, rotation, scale), and generate render and depth map images transmitted to Presti's AI pipeline for lifestyle image creation.

Front-end development for Pebble (pebblelife.com), a California-based startup backed by former Apple, Tesla, and Rivian engineers, marketing the Pebble Flow – an all-electric camping trailer positioned as the iPhone of the RV world.

The mission covered the development of new marketing pages for the site, featuring advanced animations created with GSAP (transitions, scroll-driven animations, product staging effects), as well as pixel-perfect integration of UI mockups for mobile and desktop responsiveness.

The main project was the complete development of the order configurator (/build), the user journey allowing customers to customize their Pebble Flow (choice of trim, options, colors), lock their configuration, and finalize their order – a critical flow directly linked to sales.

Stack: Next.js, React, TypeScript, GSAP.
