I'm a Web Accessibility Specialist and Front-end Developer from Chile. I've been certified Web Accessibility Specialist (WAS) by the IAAP, and I'm dedicated to ensuring that the digital world is accessible for everyone. My work revolves around making websites accessible to all users. I am well-versed in the Web Content Accessibility Guidelines (WCAG) 2.0 and 2.1. I conduct accessibility audits to help businesses achieve compliance with the Americans with Disabilities Act (ADA). My audit process involves thoroughly examining websites and performing both automatic and manual testing, identifying accessibility issues, and creating a comprehensive accessibility report. This report includes an executive summary, scope and methodology, and detailed findings organized by categories where every logged issue contains information of how to fix it. My goal is to help businesses understand where they currently stand in terms of accessibility, and provide actionable recommendations for improving accessibility for all users.
