MMM-Pinfo(MagicMirror² Telemetry Module)
A real-time hardware telemetry and system monitoring module for MagicMirror² smart displays with customizable threshold alerts.
Semantic Search(AI Vector Search Engine)
An AI-powered search system translating keywords into meaning using vector embeddings and similarity index matching.
Smart Mirror(AI/IoT Smart Mirror)
An interactive IoT smart mirror combining face recognition, real-time widget displays, and voice commands.
02 / PHILOSOPHY
"I don't want to only write code. I want to build things that matter."
1. Systems-First
I map complex relations, database flows, caches, and queues before laying down code. A smooth system prevents developer overhead.
2. Pragmatic AI
I build practical AI features—like semantic vector searches, OpenCV edge triggers—that solve real user interaction problems.
3. Clean Packaging
I focus heavily on packaging reuse, zero dependencies when writing tools (like V-Signature), and highly readable codebases.
