# Leone Daher > Public portfolio covering mobile engineering, connected systems, AI automation, selected published apps, verified course records, and an article about the LD visual identity. English is the default at the root; Portuguese documents are available under /pt/. The Markdown versions mirror the public portfolio copy and selected public evidence. Cases describe contribution within teams; store listings are product evidence. The contact section gives the public professional channels. The 14-app count belongs to the Latitudde/Conkord inventory of Android and iOS deliveries. MAG Venda Digital is excluded; the count does not mean 14 individually authored products. Case studies describe Leone's role and contribution within teams. A store listing supports the existence of a published product, but does not establish sole authorship or responsibility for the entire product. Store metrics are snapshots checked in July 2026. Values with + and rounded summaries such as 11.5K+ are not exact counts or current measurements; ratings, downloads, and availability may change. Certificates document completion of the listed courses. They do not, on their own, establish professional experience, technology mastery, or current language fluency. The MAG evidence records a collective delivery. The post URL and date are reproduced when present in the selected public record; missing fields remain unknown. Português: os documentos abaixo reproduzem o conteúdo público do portfólio. Os 14 apps pertencem ao inventário Latitudde/Conkord, sem somar MAG. Métricas de loja foram consultadas em julho de 2026; cursos não substituem experiência profissional. ## English - [Leone Daher — Software Engineer](https://leonedaher.com/index.md): Mobile products powered by smart, connected systems.
