Experience
Schoolrun Application
Many schools in Nigeria still rely on old paper and pen to keep track of students' records and activities. The challenge that comes with this old method, apart from the obvious stress teachers go through to keep track of students' activities, is the inability to derive useful insights from past records. Storing data in paper guarantees that helpful information can assist the children and their parents remains undiscovered. This problem and many other school-related challenges are what the application solves.
I developed the web interface of this solution and led a team of mobile developers to implement a mobile application for teachers and students.
Integrated Governance Risk and Compliance Solution
Staff can also raise issues and risk events as they occur, keep track of all the risks that have crystallized over time and determine the root cause to prevent future occurrences or at least minimize the impact. The solution also has a workflow management feature to handle all kinds of tasks and reviews within the bank.
I led the back-end team to deliver this solution in a record time.
