Willis Nana - Senior Data Engineer
Coach and mentor in Data Engineering

Creates simple solutions to complex problems

With nearly 10 years of experience, I'm specialized in Data Engineering, Business Intelligence and Data Science. My daily work is to create data model, ETL/ELT/Data Pipeline and Big Data tools but also train Data Analysts and Data Scientists in the use of data.

Positive impact on the final product is one of the most important things in my work.

I also offer training in Data Engineering and Data Science (available very soon)

More than technical aspect, the success of data projects is based mainly on human aspects: cooperation, empathy and commitment.

 The first edition of Ralph Kimball's The Data Warehouse Toolkit introduced the industry to dimensional modeling, and now his books are considered the most authoritative guides in this space. This new third edition is a complete library of updated dimensional modeling techniques, the most comprehensive collection ever. It covers new and enhanced star schema dimensional modeling patterns, adds two new chapters on ETL techniques, includes new and expanded business matrices for 12 case studies, and more.

 Blending the informed analysis of The Signal and the Noise with the instructive iconoclasm of Think Like a Freak, a fascinating, illuminating, and witty look at what the vast amounts of information now instantly available to us reveal about ourselves and our world - provided we ask the right questions. By the end of an average day in the early 21st century, human beings searching the Internet will amass eight trillion gigabytes of data. This staggering amount of information - unprecedented in history - can tell us a great deal about who we are - the fears, desires, and behaviors that drive us and the conscious and unconscious decisions we make. From the profound to the mundane, we can gain astonishing knowledge about the human psyche that less than 20 years ago seemed unfathomable.
