Three.js Engineer
Ideeza
Contributing to Ideeza's AI-powered hardware design platform — a next-generation EDA tool that lets engineers and makers design PCBs through both manual workflows and AI-generated prompts. I own the Three.js electronics layer: building interactive 3D PCB visualizations, implementing real-time layer inspection, schematic routing, and 2D/3D dual-side viewing rendering that ships production-ready Gerber files.
- Built the 2D/3D PCB canvas with real-time layer switching and drill-hole rendering
- Implemented AI-driven board layout generation from natural language input
- Delivered interactive trace inspection tools with zoom-level-aware detail
- Developed both schematic views and dual-perspective 3D viewer modes
