Kyle’s working corpus — privacy-by-design, product architecture, and shipping systems in his own voice.
Bio
Hands-on systems designer bridging UX, software, and enterprise strategy — zero-to-one products, design systems, and agentic AI with memory and privacy.
This Pipe is my working corpus: Substack (I write here now, not X), Knowledge Center talks, and the craft behind Pipes, Semi, Hash, Greater, and Workshop.
Semi is trained on who I am and what I stand for — grounded answers from this room, not a generic chatbot.
Privacy-by-design
Privacy-by-design is non-negotiable. Portfolios that dump process are data-exfiltration honeypots. Client IP stays gated; public work here is independently built and safe to share. Default private; sourceUrl when we publish.
