Hi, I'm William Josh 👋

I am a 15-year-old AI & Full-Stack Engineer focused on high-velocity shipping, GPGPU processing, and resilient agentic architectures.

🏆 Global Ranking: Placed 10th globally in the San Francisco Agentic AI Hackathon. 🚀 Focus: Building self-healing pipelines and web-based parallel compute environments.

🛠️ Featured Shipped Projects

🎙️ AI-Dubbing-Tool

A production-ready, multimodal multilingual dubbing pipeline featuring an enterprise-grade resilient voice engine.

  • Resilience Pattern: Engineered a 4-tier automated fallback cascade (ElevenLabs ➔ Coqui/XTTS ➔ Google Cloud ➔ gTTS) to handle live API rate limits and zero-downtime failures.
  • Core Tech: faster-whisper, Flask, Multi-Engine TTS, Segmented Temporal Translation Alignment.

🎮 Physical-Sandbox-v1.0

A high-performance, web-based 4D physics simulation sandbox utilizing web graphics hardware for parallel processing.

  • Optimization: Offloaded heavy particle calculations completely from the CPU to the graphics card using custom GPGPU fragment shaders.
  • Core Tech: Three.js, WebGL, GPUComputationRenderer, Custom GLSL Shaders.

📊 Tech Stack & Architecture Capabilities

  • Languages: Python, JavaScript, GLSL (Shader Language), HTML/CSS
  • AI/ML Pipelines: Whisper, XTTS, LLM Orchestration, Agentic Simulation Frameworks
  • Frontend/Graphics: Three.js, WebGL, Reactive UI Components
  • Backend: Flask, Event-Driven Orchestration, API Management
