Industry Experience

Software & Internet, Government, Professional Services, Media & Entertainment
    paper Spaceship Drive | R3F | Web 3D

    https://www.twine.net/signin
    Interactive 3D experience built with React Three Fiber and Drei, focused on delivering an immersive, space-themed environment with dynamic visuals and responsive interactions.
    The project incorporates advanced rendering techniques such as post-processing effects, HDRI environments, multiple light sources, real-time shadows, and renderer-level optimizations to enhance visual depth and realism. A parallax effect driven by mouse movement adds an additional layer of interactivity, while smooth transitions between scenes create a cohesive experience.
    State management is handled with Zustand, enabling a clean and scalable structure for managing application and game states. The codebase is organized into reusable components, following best practices for maintainability and performance.
    3D assets were created in Blender, including the use of procedural noise to generate detailed normal variations on specific spaceship elements. The experience also integrates audio feedback tied to user interactions, UI/HUD styling with CSS, and a mobile-first approach to ensure accessibility across devices.
    This project demonstrates strong expertise in real-time 3D applications, React-based rendering pipelines, interactive design, and game-like state management within the browser.

    paper Mediterranean Drive | Threejs | Web 3D

    https://www.twine.net/signin

    Three.js-based project focused on creating and showcasing a stylized “cozy” 3D world, designed to deliver an immersive and atmospheric experience in the browser.
    All 3D assets were modeled from scratch using Blender, including texture baking workflows to achieve optimized and visually consistent results. Models and materials were further refined and integrated within Three.js for real-time rendering.
    The project leverages advanced Three.js features such as OrbitControls for navigation, custom shader development for realistic water effects, and positional audio to enhance spatial immersion. It also includes lighting design, renderer optimization for performance, and a lightweight HTML loading system to handle asset initialization smoothly.
    This work highlights strong skills in 3D pipeline integration (modeling to web), real-time rendering, shader programming, and performance optimization for interactive web experiences.

    paper Customize Your Room|Web 3D|Threejs

    https://www.twine.net/signin
    Interactive 3D web application for real-time room customization, allowing users to intuitively move, rotate, and arrange furniture and decorative elements to visualize and experiment with different spatial layouts.
    Built with vanilla JavaScript and Three.js, the project follows a scalable, class-based architecture inspired by game development patterns, enabling clear separation of concerns and feature-driven structure.
    Key highlights include the integration of PBR 3D models, performance-focused optimization of assets (geometry and textures), and smooth rendering tailored for browser environments. The application also incorporates CSS-based animations and adopts a mobile-first approach to ensure responsive and fluid interactions across devices.
    This project demonstrates strong capabilities in real-time 3D rendering, performance optimization, and advanced frontend architecture beyond traditional UI development.
