Product Design Leadership for SaaS, AI, and Enterprise Products.

Hi, I'm Derry Birkett. I help SaaS and AI companies simplify complex products, scale design systems, and deliver measurable product outcomes. Previously I led UX at CloudBees and delivered design systems and enterprise product initiatives for Oracle NetSuite.

I work best where depth matters: untangling information architecture, building research rigour, and setting the quality standards that make the team around me better.

Designed at scale. Led, hired, and shipped.

Four anchor cases show the through-line: organisation design at CloudBees, enterprise systems at Oracle Netsuite, 0→1 product work at Exabyte, and full-stack UX leadership at Telanto.

Current thinking

The work is shifting again.

I write about design systems, UX maturity, and AI-assisted product work, and keep a blog archive of demos and experiments when the idea needs to be felt rather than explained.

The Audit Agent Doesn't Get Bored

I built an agent whose only job is to catch when my autonomous pipeline breaks. It worked perfectly for two weeks straight. The thing it caught was me.

The Skills That Only Worked On One Machine

I opened Claude Code on my phone mid-task and /pickup didn't exist. The cause was a submodule nobody had initialized, and the fix taught me why --recursive is the wrong default.

Learning by Archiving Projects

What three retired systems-thinking projects taught me about AI agents, publishing loops, and the difference between scaffolding and learning.

Discovery without the sprint

Product opportunities don't wait for your next research sprint. NVSBL is a test of whether autonomous agents can keep scanning while you're building.

Building a Portfolio Web App: Agents, HITL, and 99 RES

How I rebuilt my portfolio as a real web app, what the HITL + agent development loop actually looks like, and what 99 RES means when you own your stack.

Moirai: Orchestrating Thin LLM Agents Without the Bespoke Wiring

How I extracted two LLM agents — Curator and Auditor — into independent repos, then built an orchestrator that lets any of my projects install them with one command.

Curator

A scheduled read-only agent that scans the codebase overnight and files GitHub issues for dead exports, oversized files, and stale placeholders — without ever touching the code.
