I work at G.Breuer, the most prestigious Trademark and Patent Office in Argentina since 1985. I developed a career here from DataEntry level to SysAdmin. ©

By Day from Monday to Friday: working as usual (almost 11 years, so boring and no career development) By Saturday and Sunday: tend to working as Freelance but have no channel. If got hired, will put a resign letter from current company and join with a good and high motivated company. Cheers, Johan Ho ©
