About me

With 10 years of experience working as a Hybrid Professional between Finance and Data Integration, I developed a passion for tools used to manipulate data. I have a strong passion for Programming, Data manipulation, ETL processes and of course Data Visualization. It gives me joy to be given massive data that many might look at and say “oh no this is too tedious for me to even look at” and instead  break it down and make it easy to digest and interpret. I really look forward to meeting with you all. Kindly see attached my most updated resume.
