I am a data professional with a strong focus on various aspects of data, particularly data science and engineering.

Currently residing in London, Ontario, Canada, I was originally born and raised in Botswana. My journey into the world of data began through my computational intelligence research for my Masters Degree.

With my background in telecommunications engineering, I found myself in a privileged position to explore the significance of data within a major industry. Apart from my passion for data, I thoroughly enjoy spending time outdoors and capturing moments through photography.

I also have a great sense of humor and cherish a good laugh.
I proudly support Liverpool FC.
"You'll Never Walk Alone" resonates with me.
