Design System and Handoff
Design Systems That Keep AI-Assisted Product Delivery on Track
I help teams build reusable UI systems that designers, engineers, and coding agents can apply reliably without multiplying inconsistency at machine speed.
How I Help
- Define tokens, components, states, and interaction APIs that reflect how the product actually works.
- Keep usage guidance, intent, examples, and implementation constraints close to the code where people and agents can find them.
- Add feedback loops such as off-token linting, accessibility checks, component validation, and visual regression testing.
- Establish ownership for canonical patterns, exceptions, deprecations, and the ongoing health of the system.
- Create a handoff model that lets teams move quickly while preventing local shortcuts from becoming the next generated standard.

Design Systems Are No Longer Optional
Mandy Michael · 6 June 2026
Mandy Michael argues that once AI generates a meaningful share of UI, the design system becomes the source of truth models execute against. The article sharpens HAAM's focus on repo-native context, drift control, automated feedback, and accountable ownership.

WiFi.ee Purchase and Account Journey
Cross-platform telecom and eSIM work where product selection, activation, account management, and trust signals had to stay clear across web and mobile.
- Mapped high-intent purchase and activation steps across multiple surfaces.
- Clarified product choice, account actions, and lifecycle touchpoints.
- Balanced conversion needs with implementation constraints and ongoing product support.

FAQ
Do you create systems from scratch or improve existing ones?
Both. I can bootstrap a system or refine an existing one based on team needs, product maturity, and roadmap pressure.
Will this slow down delivery?
The goal is the opposite: faster and more predictable shipping with fewer inconsistencies and rework cycles.
Do you include accessibility in design system work?
Yes. Accessibility and interaction states are built into component standards and handoff documentation.
How does AI change design system work?
AI agents generate against the code and guidance they can see. That makes repo-native documentation, tight component APIs, automated checks, and clear ownership essential for preventing drift at scale.
