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.
About
18 years. Enterprise, scaleup, agency, 0→1.
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.

ArticleMonospace Design System
A calm, mobile-first design system — tokens, components, nine interactive patterns, and a shadcn registry theme.
AgentCurator
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.
ToolDelta
An autonomous system that installs as a git submodule and delivers a daily pull request via GitHub Actions — AI agents pick what to build, write the spec, and ship the code.
AgentLedger
A daily audit agent that checks whether the Delta Suite pipeline did what it was supposed to do overnight — silent on success, opens a ledger/gap GitHub issue when something diverged.
AgentMerge
A GitHub Actions agent that enforces a 24-hour review window and runs an AI safety check before merging or blocking any PR — part of the MakerSuite trilogy alongside Delta and Council.
