They say we are mostly a product of our experiences.I am very fortunate to have been exposed to hybrid engineering, science, and economic disciplines that deals with electric current, fluid, and thermal flows.Consolidating these experiences and amplified by technology, I continuously yearn to learn and improve what is attainable by these disciplines sustainably with the aid of technology.This has helped shape the way I listen, think, design, develop, architect, tackle/anticipate problems, recommend and execute viable scalable solutions. I am very passionate about most things in the realm of energy trading, project finance, IoT, utilities, rail, fintech, insurtech, autonomous vehicles, electric vehicles, robotics, space and of course, technology.
