Being able to take complex concepts and explain them simply is a very important skill to have!”

“Alexander Kolovos, in my now 29th year of working in corporate America, and 36 years working in total, is one of the best frontline engineers that I have had the privilege of working with. I have known Alexander since 2014, and he was in the vanguard of a movement within Teradata to move beyond data products towards incorporating a solid data science capability into the core product. In fact, he was one of the first of a small and often under-appreciated group of engineers that did some pioneering work around abstracting Python and R functions by putting an easy-to-use SQL layer on top by which advanced data science algorithms and functions could be widely deployed by a wide range of personas on the massive data that was stored in the Teradata system. The result was an overnight explosion of the numbers of use cases that were open to be addressed for our many customers and obviously with that an increase in the market footprint for the company. Alexander, in my view, was a central reason for this to happen. You had to have been there at that time to appreciate it: Here was an organization with hitherto a main muscle of speaking the language of rows, columns, data speeds, and the like. Alexander’s work now put that vernacular solidly amidst the urgencies of addressing important business outcomes such as fraud detection, retail churn, telco customer satisfaction, customer experience understanding, and more. This was the pivot that transformed industry fortunes and one could draw a clear line, as I and others have done, to establish causality with the work Alexander did. In short, a world class engineer.
Great thing about his pedagogy is that he melds the theoretical with the practical and often uses that skill to convey the meaning of his work and its impact to customers – like I said above, one of a kind […] that instantly ups an enterprise’s EQ and IQ.”
