I worked with financial institutions in Africa to create transaction reconciliation, reporting, and credit scoring solutions.

2014 to 2016

It was great working with Sean at AfricaPay. I have found him to be a very well organised, process oriented and hard working developer. He has contributed a lot to the company through his expertise and development skills. I would definitely recommend him for any development/ programming tasks.
