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.
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.
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.
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.

Monospace Design System
A calm, mobile-first design system — tokens, components, nine interactive patterns, and a shadcn registry theme.
Agent
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.
Tool
Delta
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.
Agent
Ledger
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.
Agent
Merge
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.
Agent
Council
A repository of role-based advisor plugins — CTO, CISO, Developer, Product — installable as a git submodule. Each advisor has explicit scope, playbooks, and escalation rules. Part of the MakerSuite pipeline alongside Delta, Merge, and Ledger.
Tool
NVSBL
A three-repo suite built around a central question: can autonomous agents continuously discover product opportunities and surface the best ones for review? An invisible engine scans and scores signal, a public API packages approved findings, and an authenticated app closes the loop from discovery to delivery.
