I am a teacher and administrator, though not I exercise such activities. I work as a civil servant in CEDAE - the sanitation company in Rio de Janeiro. I like to create using scrap, disseminate, and improve my inventions. --------- Sou professor e administrador, mas não exerço essas ativides, trabalho como servidor público na CEDAE, a companhia de saneamento básico do Rio de Janeiro. Gosto de criar usando sucata e de mostrar o que invento.
