🚀 Core Featured Projects

Featured System

1. XR Immersive Digital Ecosystem (IUMAFIS 40th Anniversary)

An interactive, modular software ecosystem deployed across large-format hardware stations. It features five independent interactive modules designed to process and visualize historical institutional data.

• Identity Mirror (AR): Implemented face-tracking computer vision via MediaPipe for real-time virtual overlay of academic regalia.

• Optimization: Handled extreme performance profiling via texture atlasing and draw call reduction to guarantee continuous 60 FPS execution under massive user concurrency.

• Architecture: Structured using modular C# design patterns separating low-level hardware capture from the graphics rendering pipeline.

2. Braines – Computational Thinking Escape Room

A virtual reality educational prototype commissioned to introduce advanced gamified learning models for academic institutions. It translates computer logic structures and algorithmic problem-solving into spatial gameplay mechanics.

• Accessible VR: Integrated Google Cardboard SDK targeting mobile platforms to bypass expensive hardware requirements for public schools.

• Mechanics: Programmed complex logic restraint mechanics for level puzzles (sequential object placement arrays and circular constraint layouts).

• UX Interaction: Designed a precise timed "Gaze Selector" raycast system to let users interact completely hands-free.

3. Cleire Assistant – Voice-Driven Augmented Reality Retail

A smart AR business application created to combat friction and delay in digital conversion funnels. It features an instant spatial product presentation system directly synchronized with inventories.

• Environment Tracking: Leveraged ARCore algorithms for real-time surface plane collision and stable spatial anchors.

• Smart UI/UX: Integrated a voice command interaction pipeline allowing multi-language speech navigation.

• Dynamic Asset Loading: Instantiates interactive 3D models and high-fidelity graphics depending on conversational live queries.

4. AstroLearn – Immersive Space Exploration

An educational narrative sandbox developed to teach planetary physics and celestial structures through interactive Mixed Reality pipelines.

• Cross-Modal XR: Blends mobile Virtual Reality (Google Cardboard plugin) with Augmented Reality modules inside a single rendering build.

• AR Marker Systems: Utilized Vuforia Engine tracking matrices to display complex solar system models accurately over physical environments.

• Space Mechanics: Programmed interactive 3D mechanics within digital spaceship cockpits for exploratory learning.

🕹️ Mechanics & Feature Demos

Short technical tests focusing purely on mechanics, netcode physics, and gameplay prototyping.

Zombie Attack Prototyping

A focused gameplay test implementing modular combat architectures, shooter state-machines, raycast hit detection, rigid animation event bindings, and basic AI navigation tracking arrays.

Survival Online Netcode Test

A lightweight network test evaluating multiplayer game states using Photon Engine. Realized stable data synchronization loops for character transformation arrays, remote player instantiation, and physics replication.
