Over the past few years, I have worked with many consultants. Some can be very easy to work with while others can be a little challenging. Some of the consultants I worked with were from a company called AquaQ Analytics and they were probably the best ones I have worked with.
For those who don’t know, AquaQ is a consulting company that specializes in data management, data analytics and data mining services (mainly through kdb+). They are also very good with sharing what they have been working on. For example, few years ago, they released TorQ which is a framework for setting up kdb+ stack easily (RDB, HDB etc).
