Web Accessibility Compliance & ADA/WCAG Design Services

Once discovery is complete, we conduct a full gap analysis against the applicable WCAG criteria. We evaluate the product against the four WCAG principles and identify both conformance failures and risk areas. These are places where current development patterns are likely to introduce new violations over time. Findings are documented with severity ratings, affected user groups, and remediation priority so the team can make informed sequencing decisions.

Before remediation reaches the code level, we address accessibility at the design level. We revisit the component library, color palette, typography, and interaction patterns — updating designs where they fall short of contrast ratio requirements, keyboard accessibility standards, or inclusive design principles. For new builds, this phase establishes the accessible design system. For remediations, it produces a specification that guides the engineering work to follow.

Our frontend engineers implement the changes identified in the audit and design phases. This typically includes updating semantic HTML structure, adding ARIA attributes, correcting focus order and keyboard navigation flows, fixing color contrast in CSS, and ensuring that JavaScript-driven interactive elements behave correctly for assistive technology users — including proper handling of animations and dynamic content that screen readers need to interpret correctly.

We validate the remediated product through automated testing tools and manual testing with assistive technology before delivery. For organizations with ongoing compliance obligations, we can establish monitoring workflows that catch regressions whether they come from new features, design system updates, or third-party integrations. Accessibility compliance does not end at launch; the monitoring phase is what keeps it from having to start over.

Accessibility failures often live at the boundary between design and engineering. A design decision that looks correct in a mockup produces inaccessible markup in code, or a component built correctly breaks when the design system is updated. We keep design and development on the same team, which means accessibility decisions made in design are carried through to the code — and the people who built the component can validate it against the final implementation.

Big Human has helped organizations across industries bring digital products into compliance. That experience shapes how we scope, prioritize, and execute accessibility projects across a range of sizes and starting points.

Some accessibility providers specialize in audits; others in remediation. Big Human covers both, which means the team that identifies your compliance gaps is the same team that closes them. There is no translation layer between the audit findings and the implementation work, which reduces the risk of remediation decisions that are technically correct but miss the intent of the original finding.

We build accessibility into the foundations of digital products. Semantic HTML from the start, accessible component libraries, and design systems where WCAG conformance is a documented requirement at the component level. Products built on accessible foundations can scale without accumulating the kind of accessibility debt that eventually requires a full remediation cycle.

Inclusive design recognizes that designing for the full range of user ability makes products better for everyone. A site that works for a user with low vision is easier to read on a bright screen. A keyboard-navigable interface is more efficient for power users. Color contrast and readability standards that accommodate color blindness and dyslexia improve the experience in general. We approach accessibility as a design quality standard, not a compliance exercise.

Accessibility is not a project that ends at launch. New features introduce new patterns; design system updates touch components across the product; third-party integrations bring in code outside your team's direct control. We can stay on as a long-term partner — monitoring compliance, validating new development against WCAG standards, and providing the expertise your team needs to sustain accessibility over time. Some clients engage us for a defined project; others build an ongoing partnership. We are flexible based on what your team needs.
