I think in systems, build in code, and teach from the work.

I'm a software architect and the founder of Casys, based in Taiwan. I work where agent protocols, engineering models, business systems, data, and decision-making meet.

I like turning complicated real-world work into software that is executable, inspectable, and useful to the people who own it.

I develop tools and software on my personal GitHub. Existing npm and JSR packages keep the @casys namespace.

Through Casys — Complex Adaptive Systems, I contribute to the discipline of Agentic Process Engineering (APE) and offer consulting and education on the design and governance of processes with AI. Casys publishes the APE handbook and its supporting resources.

I provide no-code training through THE NO CODE GUY, my legal company, which operates the Casys brand.

• Agent infrastructure — MCP systems and operator surfaces that connect agents to the tools, permissions, knowledge, and traces behind real workflows.
• Engineering software — from system architecture to CAD and simulation, with evidence that carries into the wider workflow.
• Data, graphs, and optimisation — knowledge structures, exact models, heuristics, and interfaces that make difficult decisions legible.

understand → model → build → run → document → teach

I publish field notes, diagrams, and working examples alongside the code. Documentation is part of the product, and teaching is how I test whether the ideas remain useful outside the repository where they started.

My tools and software live on my personal GitHub. These projects capture the range:

• mcp-platform — a TypeScript framework for MCP servers, apps, and composition.
• casys-trader — experimental LLM-assisted paper trading with explicit risk controls and traceable decisions.
• casys-digital-thread — experimental engineering workflows from reviewed intent to traceable artifacts and evidence.
• mcp-erpnext — agent-operated ERPNext documents and workflows with interactive views.
• editorial-workbench — a local editorial reader for HTML manuscripts and detailed Markdown outlines.

NutrientCompare is a transparent supplement comparison project built for Taiwan.

If you're building a system where an agent needs to do more than talk, say hello.
