João Dias
I'm a Senior Frontend Engineer specializing in Web Accessibility from Portugal.
A privacy-first PWA that compresses images, SVGs, PDFs and MP4 videos entirely in the browser.
A single-screen reference for exploring artists and the relationships between them.
A local-first platform for repeatable accessibility audits across URLs, sitemaps, crawled sites and test plans.
I help organizations build accessible, high-performing digital experiences that don't just meet EAA, ADA, and WCAG standards - they exceed them, creating sustainable compliance frameworks that scale with regulatory evolution.
Hands-on, tailored training that aligns corporate and academic teams on accessibility best practices. I translate complex standards into actionable workflows that ensure WCAG, EAA, and ADA compliance while establishing scalable, inclusive Design System foundations.
Engaging presentations and keynotes for conferences, companies, and universities, exploring the intersection of UX excellence, frontend performance, and strategic accessibility planning.
Building high-quality, high-performance web applications with an unwavering focus on global accessibility compliance and governance.
Strategic, in-depth analysis of existing codebases, delivering clear, actionable roadmaps to achieve international legal compliance, optimize performance, and elevate product quality.
I am also a radio host at Rádio Universidade de Coimbra (RUC), where I regularly broadcast shows that range from Jazz, Blues, Rock, Punk and Heavy Metal.

O Roque de Pai despede-se da grelha regular com uma descarga completa de 20 faixas de skate punk dos anos 90 e 2000. Dos NOFX aos Dag Nasty, passando pelas recordações de moshpits e piadas de pai, uma hora sempre a abrir antes da transição para a grelha de verão da RUC.

Uma viagem ao coração industrial de Birmingham, a cidade que inventou o Heavy Metal. Dos pioneiros Black Sabbath às correntes mais extremas e abrasivas do death metal e do industrial, o Mel e Tal mapeia a linhagem do aço britânico e abre o microfone ao formando Hugo Rocheta para uma crónica especial sobre o Grindcore.

O Roque de Pai celebra o início do Verão com uma descarga de punk rock dos anos 70. Recebemos a Rafaela Alves para uma crónica especial sobre os 50 anos do primeiro disco dos Ramones, ligando a Nova Iorque underground à explosão britânica dos Sex Pistols e The Damned.

Do Thrash clássico dos anos 80 às explorações atmosféricas contemporâneas, o Mel e Tal analisa como o heavy metal serve de veículo para a consciência ecológica e o ativismo ambiental. De Gojira a Lamb of God, sintonizamos as distorções que alertam para a preservação do planeta e os direitos dos povos indígenas.
