Born prematurely and fully blind by age nine, he navigated inaccessible university systems, discovered vulnerabilities in Google, Microsoft, Nubank, and Smiles using only a screen reader, and published CVE-2025-26326 in NVDA Remote add-ons. He also founded BNVD.org, a Portuguese-language alternative to the NVD, authored Brazil's first cybersecurity book by a visually impaired person, and holds 50+ certifications. The post candidly addresses the real accessibility barriers blind professionals face in tech — from inaccessible websites and mobile apps to 500+ job applications with zero callbacks — and advocates for inclusive design as a professional necessity, not a niche accommodation. ## Full article daily.dev links to this article rather than hosting it.
