Physical Data Modeling SQL Big data Hive Apache Spark Architectures Data Modeling Data Warehousing Oracle Databases
I have over 22 years of experience in IT industry, more than 15 years of which is in Business Intelligence and Data Warehousing solutions, with many successful implementations for customers like McGraw-Hill Education, EMAP, Hachette Book Group, British Telecommunications, Cell C. My experience encompasses the entire SDLC cycle of Data Warehousing, starting from Pre-Sales, carrying out BI Blue Printing through Requirement Analysis, Architecture definition, Design and Development, and post production second and third line support. I have seen through multiple data warehouse implementations end to end, from requirement definition through to post production support.

Data Warehouse solution is my passion, and I have helped many other implementations for clients like LifeStyle, Arrow Electroncis, JCPenny.

My last implementation was for Cell C, a Telecom operator at South Africa, where I architected their EDW and successfully implemented it, consolidating their multifarious departmental data marts onto a Oracle platform, integrating data from more than 30 source systems. This platform now provides cross departmental operational intelligence to Cell C, and have improved on their monthly and daily reporting cycle markedly.

I am currently leading the Big Data Analytics practice in the Oracle Center Of Excellence at Tata Consultancy Services where we are developing a slew of exciting solutions.
