About
Weidong Shi
Senior Technology Architect focused on shipping reliable software — clear domain boundaries, practical AI-assisted workflows, and products that hold up in production.
This site is the long-term hub for the AI in Action series, RetireCheck, upcoming applications like Sleep App, technical case studies, and writing about architecture and delivery.
The goal is simple: demonstrate how thoughtful engineering and modern AI tooling combine into real, usable products — not demos.
Focus
How I work
Principles that shape products, architecture, and collaboration.
Domain first
Financial and product rules live in clear domain layers — not in UI components or controllers.
AI-assisted, engineer-owned
Use AI to accelerate scaffolding and exploration; keep judgment, testing, and architecture human-owned.
Production over prototypes
Deployable systems, CI, docs, and honest disclaimers matter as much as the happy path demo.
Composable ecosystem
Each app and article should stand alone while feeding a coherent personal brand and product portfolio.
