A11Y ENGINEERING · WCAG 2.2 AA · LEGAL COMPLIANCE EAA & ADA

Web Accessibility (A11y) & WCAG 2.2 AA Certification.

Is your digital platform protected against accessibility lawsuits, or is it shutting out the 20% of the global population living with disabilities? At Berlo Desarrollos, we audit, remediate, and certify your source code under international WCAG 2.2 Level AA/AAA standards, ensuring genuine digital inclusion and total legal shielding across the Americas and the European Union.

We reject cosmetic, legally flawed overlay widgets. We engineer authentic, barrier-free accessibility directly into your native source code (semantic HTML5, full keyboard navigation, ARIA roles, and screen reader optimization with NVDA, JAWS, and VoiceOver).

Inclusion & Business Strategy

Why Web Accessibility Defines Your Company's Market Reach and Profitability

Accessibility is not merely a legal checkpoint; it is a major driver of market expansion, SEO superiority, and brand loyalty.

Over 1.3 billion people worldwide live with significant disabilities. When your company's platform fails to support assistive screen readers, keyboard navigation, or color contrast, you systematically block 15% to 20% of your potential customer base from purchasing your services or products.

At the same time, regulatory pressure is accelerating globally: the European Accessibility Act (EAA 2025) and ADA Title III in the United States hold organizations directly accountable for inaccessible digital channels. At Berlo Desarrollos, we remediate your native code to ensure your platform provides a welcoming, barrier-free experience while providing permanent legal shielding.

Core A11y Capabilities

Audit, Remediation, and WCAG 2.2 Certification Services

End-to-end technical engineering to turn accessibility barriers into operational strengths.

01
DIAGNOSTIC AUDIT

Comprehensive WCAG 2.2 AA Audit

Automated scans paired with expert manual screen-reader testing.

We audit your digital platform across all 55+ WCAG 2.2 Level AA success criteria. We evaluate DOM architecture, color contrast, keyboard focus traps, screen reader announcements (NVDA, JAWS, VoiceOver), and interactive widget semantics.

Outcome: Exhaustive technical VPAT report identifying exact lines of code and remediation instructions.
02
NATIVE REMEDIATION

Native Source-Code Remediation

Direct engineering in your code without cosmetic overlay plugins.

Our engineering team directly refactors your frontend code: replacing non-semantic divs with HTML5 landmarks, implementing accessible keyboard focus trapping, engineering ARIA live regions for dynamic alerts, and correcting form labels and error bindings.

Outcome: Permanent barrier elimination directly in your repository without recurring third-party widget fees.
03
LEGAL COMPLIANCE

EAA & ADA Legal Shielding

Formal certification protecting your brand from regulatory litigation.

We draft your official public Accessibility Statement and deliver formal VPAT/ACR compliance documentation conforming to European Standard EN 301 549 and US Section 508 / ADA requirements, safeguarding your enterprise against lawsuits.

Outcome: Full qualification for public tenders and total protection against accessibility lawsuits.
04
KNOWLEDGE TRANSFER

Accessible Design Systems & Training

Empower your developers and content editors for lasting compliance.

We build accessible UI component pattern libraries and deliver tailored engineering workshops, ensuring your internal product team preserves WCAG 2.2 standards as you launch new features and marketing pages.

Outcome: Prevention of future accessibility regression and self-sufficient development teams.
The Differentiator

How the AI-First Methodology Accelerates Accessibility Engineering

High-throughput automated diagnostics guided by 100% human specialized engineering.

Manual accessibility audits across thousands of URLs can take weeks of exhaustive scanning. At Berlo Desarrollos, we leverage specialized AI agent workflows to execute automated DOM tree traversals, parse color contrast tokens across dark/light themes, and detect missing alt attributes in minutes. Our senior accessibility engineers then manually validate user journeys with physical assistive screen readers, guaranteeing genuine usability.

Rapid DOM & ARIA Pattern Recognition

AI agent scanners analyze thousands of DOM nodes in parallel to flag missing form associations, broken landmark sequences, and unannounced modal dialogs.

Contrast & Focus State Remediation Generator

We programmatically map compliant APCA and WCAG color ratios for light and dark themes, generating CSS custom property fixes that preserve your brand palette.

Automated Regression CI/CD Testing

We deploy automated A11y tests within your deployment pipeline (axe-core / Lighthouse CI) so no commit introducing an accessibility regression ever reaches production.

Hands-On Assistive Technology Testing

Machines cannot replicate the lived experience of disabled individuals. Our senior human engineers personally test every checkout, form, and modal with NVDA, JAWS, and VoiceOver.

Why Choose Native Code Remediation vs. Floating Overlay Widgets?

A clear technical and legal evaluation to protect your enterprise and respect your users.

Evaluation Criterion Berlo Native Remediation (WCAG 2.2 AA) Automated Overlays / Widgets (Third-Party Plugins)
Legal ADA & EAA Compliance 100% Validated in Source Code Frequently rejected in federal courts; high lawsuit rate
Screen Reader Experience Native HTML5 semantic landmarks Blocks VoiceOver/NVDA shortcuts; user frustration
Impact on Page Load Speed Zero latency overhead (Eco-design) Adds 200KB - 500KB of external JS; harms Core Web Vitals
Privacy & Data Compliance (GDPR) No third-party tracking or cookies Injects third-party telemetry scripts and cookies
Cost Structure One-time engineering asset (Permanent) Endless monthly SaaS subscription fee
Transparent Process

Resolution of Doubts

Frequently Asked Questions about Web Accessibility (A11y)

Everything you need to know about compliance, remediation, and certification:

Why do third-party accessibility widgets or overlays fail legally?

Overlays and automated JavaScript plugins attempt to disguise accessibility barriers with a floating toolbar instead of resolving structural defects in the source code. Consumer advocacy groups, blind user associations, and federal courts have repeatedly ruled that widgets fail to satisfy ADA or WCAG standards, and actually introduce new navigation obstacles for screen reader users. Genuine accessibility requires semantic HTML5, valid keyboard focus management, correct ARIA attributes, and native color contrast directly in code.

What is the European Accessibility Act (EAA) and does it apply to international companies?

The European Accessibility Act (EAA 2025) mandates that all commercial websites, e-commerce stores, banking platforms, and digital services operating in or selling to users within the European Union must strictly comply with standard EN 301 549 (equivalent to WCAG 2.2 AA). Non-compliance carries severe fines and commercial operation bans, making certification indispensable for international businesses.

How does digital accessibility boost organic SEO rankings and conversion rates?

Search engine crawlers and modern AI bots (Googlebot, Gemini, ChatGPT) process websites in the exact same manner as assistive screen readers: through semantic DOM landmarks, logical heading structures, clear alt-text, and proper contrast. Remediating for accessibility directly resolves Core Web Vitals issues, reduces bounce rates, and broadens your addressable audience by 15% to 20%.

What deliverables does our company receive upon completing an audit and remediation?

You receive a formal VPAT (Voluntary Product Accessibility Template) / ACR audit report, remediated production-ready source code, a publicly postable Accessibility Statement, and an internal component style guide for your engineering team.
