Senior Product Architect & Systems Builder
15+ years in systems architecture & product engineering .
Weathered multiple paradigm shifts; currently focused on AI-native workflow engines, client-side DAG schedulers, and local developer tooling.

• 🐾 PatchCat — A visual prompt orchestration engine powered by a dependency-free client-side DAG runtime and Kahn's topological sort scheduler.
• 📄 Translate_PFD_For_study — Local academic paper typesetting suite generating interleaved "one page English, one page Chinese" bilingual layouts.
• 📟 kindle-weather-station — Typographic weather & clock dashboard engineered for jailbroken E-ink devices with instant orientation and language toggles.
• ☯️ metaphysics-tools — ZhiMing: Purely static metaphysical calculation algorithms and Neo-Brutalist interactive design with zero backend dependencies.

Having operated across the full lifecycle—from massive-scale concurrent interactive platforms and global growth engines to developer infrastructure and open-source commercialization—I firmly believe that grand product abstractions must ultimately converge into robust, working code and practical user experiences.

In this AI era, I have intentionally returned to the front lines as a hands-on builder, embracing AI Pair Programming and "Learning by Doing":

• Beyond Chat Wrappers: Moving past simple prompt boxes toward node-graph topological execution, decoupled state slices, and local agent primitives.
• Milestones & Stress Testing: Grounding architecture in real workflow trade-offs, discovering underlying system boundaries and deadlock prevention through bidirectional AI collaboration, and personally verifying edge cases under extreme conditions.
• Open & Grounded: Systems are complex and architectural blind spots are inevitable. Always grounded in humility, and warmly welcoming peer discussions, architectural critiques, and code reviews.
