Accessible Web Development

Compliant from day one, remediated with focus, or protected over time.

Retrofitting accessibility is usually far more expensive than building a compliant solution from the start. I implement new websites and web apps according to WCAG 2.1 and BITV 2.0, remediate existing systems in prioritized steps, and use monitoring to keep compliance stable after updates.

Service areas at a glance

Accessible new implementation

Architecture, components and interactions are built from the outset to meet legal requirements and avoid expensive rework.

Targeted remediation

Existing systems are improved in prioritized steps based on severity, legal relevance and user impact without forcing a complete rebuild.

Ongoing monitoring

Recurring review cycles prevent regressions from content, CMS and feature updates and keep conformance measurable.

New implementation: what must be right from the start

Most accessibility issues come from treating accessibility as an afterthought. That is why requirements for semantics, operability and clarity are embedded directly into design and implementation.

This avoids costly post-project fixes, lowers legal risk and creates a stable base for future changes.

Core implementation principles

Semantic HTML

Correct heading hierarchy, landmarks, lists, forms and interactive elements as a reliable foundation for assistive technology.

ARIA where needed

ARIA is added only where native HTML is insufficient, so attributes improve usability rather than undermine it.

Keyboard and focus flow

All functions are fully operable without a mouse, with clear focus states across modals, tabs, menus and dynamic content.

Contrast and readability

Minimum contrast ratios and robust visual states are secured in design, not patched in later.

Forms and error communication

Labels, required fields, validation and error messaging are implemented to be understandable and screen-reader compatible.

Responsive up to 400% zoom

Layouts and interactions remain usable under strong zoom without loss of content or broken flows.

Technologies and frameworks

  • Semantic HTML5 and accessible CSS structures
  • TypeScript and robust UI patterns for accessible interactions
  • React, Vue or native frontend stacks depending on project context
  • CMS integration with accessible templates (e.g. WordPress, TYPO3, Strapi)
  • Documented quality criteria to support conformance evidence

Remediation: bring existing systems up to standard

Many websites evolved over years and are not fully compliant. Instead of forcing a complete rebuild, I focus on prioritized remediation with clear implementation phases.

The objective is practical impact: removing the most critical barriers in real operation.

Remediation process

Monitoring: protect conformance during change

Accessibility is not a one-off project. New barriers can be introduced through deployments, editorial updates or plugin changes.

Recurring review cycles and clear ownership keep your achieved quality level stable over time.

Typical monitoring building blocks

  • Recurring automated scans for regression indicators
  • Manual spot checks on critical page areas
  • Release support to prevent issues before go-live
  • Prioritized action lists with clear ownership
  • Accessibility statement updates after significant changes
