<h1>I build internal systems for real business and factory problems.</h1>
<p class="intro">
My work sits between enterprise architecture, manufacturing software, data integration,
and applied AI. I care about systems that are understandable, maintainable, and useful
after the demo is over.

<div class="label">How I think about systems</div>
<p>
I do not think good architecture is about making the diagram look impressive.
It is about making the important boundaries clear, reducing hidden coupling,
and giving the next engineer enough context to change the system safely.
