I am talking from Brazil and we have one very important customer that requested our support to find a consultant, deeply specialized in Cache that could work with us attending this customer. It has a tons of data and its core application is based on Cache.
If you are interested send me an email with the subject title - Cache consultant opportunity - and we will make contact with you. The main request is how strong are your skills in cache and it would be considered a differentiator if you are a portuguese speaker.
Regards - Helberth Cavalcante.
