Design System Accessibility Engineering
We make your design system components behave correctly for every user.
Component accessibility reviews
We analyse each component for semantic structure, interaction behaviour and assistive tech compatibility.
Keyboard interaction modelling
We define predictable, consistent keyboard patterns that work across your entire design system.
Focus management design
We map how focus should move, return and recover across complex UI flows.
ARIA and semantic architecture
We ensure components expose the right roles, states and announcements to assistive technologies.
Behaviour specifications for complex UI
We document expected behaviour for menus, dialogs, comboboxes, tables, tabs and other advanced patterns.
Design system governance
We help you set rules, workflows and contribution standards that keep accessibility consistent over time.
Accessibility QA for design system releases
We validate new components and updates before they ship to product teams.
Documentation and guidance
We create clear, practical accessibility guidance for designers and engineers using your system.
Assistive Technology Behaviour Testing
We validate how your product behaves with real assistive technologies.
Screen reader reviews
We test your components and pages using real screen readers used by disabled people, including JAWS, NVDA, iOS VoiceOver and Android TalkBack.
Screen magnifier reviews
We look at your content the way real magnifier users do, using tools like ZoomText, Windows Magnifier and iOS Magnifier, plus settings such as Large Cursor, High Contrast modes, Follow Focus and smaller viewport sizes.
Switch control reviews
We check your interactive functionality using switch‑control settings like the iOS Gliding Cursor, ensuring your content works for people with limited dexterity or physical disabilities.
Speech recognition reviews
We check your interactive functionality to see whether it’s navigable with speech recognition software such as iOS Voice Control, ensuring it works for people with physical disabilities.
Accessibility Audit Training
Most people are taught to audit by opening a screen reader and hoping they can interpret what it says. That approach is slow, inconsistent and hides the real problems. This training teaches you how to audit properly by interrogating the Accessibility API, the one source of truth that every assistive technology relies on.
You learn how to inspect roles, names, states and relationships directly, how to spot broken patterns instantly, and how to trace issues back to the underlying code. You understand how to think like an accessibility engineer, not a checklist follower.
VPAT/ ACR Review
A VPAT is only useful if the “supports” statements are true. Most aren’t.
I review your VPAT as an independent expert and check every claim against the Accessibility API, the single source of truth behind all assistive technologies. You get an unbiased assessment that shows whether your VPAT reflects reality, where the gaps are and what needs correcting before it reaches customers or procurement teams.
Audit Quality Check
I review audits produced by other teams and identify gaps, incorrect findings and missing root causes. You get a technical second opinion that shows what was overlooked and what actually needs fixing.
Accessibility Pair‑Programming / Engineering Support
I work directly with your engineers to fix accessibility issues in real time or through a help desk. This accelerates learning, reduces back‑and‑forth and ensures the implementation matches the Accessibility API requirements.
Accessibility Issue Triage
I review your backlog of accessibility bugs, identify duplicates, merge related issues, prioritise them and explain the underlying causes. This gives you a clean, actionable roadmap instead of a chaotic list.
Accessibility Code Review
I review your pull requests or component code to catch accessibility issues before they ship. This prevents broken patterns from entering your design system in the first place.

Frequently Asked Questions
Why do I need to do accessibility?
Disabled people make up around 25% of your audience. UK businesses lose an estimated £2 billion every month by excluding them. They are also one of the most loyal customer groups when products work for them.
Exclusion is bad for business, it is illegal, and it exposes you to complaints and legal action. Inclusion strengthens your brand, expands your reach, improves search visibility and shows customers that you take accessibility seriously.
How much will it cost?
My design system accessibility engineering can be as small as an hour of work, while full WCAG audits can take several days. It depends on what you need and how deep you want to go.
My hourly rate is £66, and larger pieces of work may need scoping so the price reflects the complexity and the deliverables. If you’re interested, get in touch. I’m happy to help no matter the size of the project.
What are my legal obligations?
Supporting people with disabilities on digital platforms is a legal requirement in many countries. Laws such as:
- Equality Act 2010 (UK) and the European Accessibility Act 2025 set clear expectations.
- If you work with public bodies in the UK, you also need to meet the accessibility standards outlined in EN 301 549.
- If you create public services you also have to adhere to the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.
What is an assistive technology?
An assistive technology is any physical device or piece of software that helps people with disabilities use an interface. This includes tools like head wands and mouth sticks for people with physical disabilities, screen readers for blind users, and digital screen magnifiers for people with low vision.
When we review your product using these technologies, we perform an expert evaluation from the perspective of a disabled user and give you insights that automated tools and sighted testing simply cannot provide. This shows you how usable your interfaces really are.
