What I bring

A whole career behind the code

01

Controls and security mindset

As an internal controller at Ecobank Ghana I monitored system access across regions, ran branch audits and trained staff on internal controls.

My software works the same way: least-privilege roles, audit logs on sensitive actions, encrypted personal data, and no single person able to record and approve the same payment.

02

Finance and business literacy

A degree in economics and hands-on banking operations on FLEXCUBE, SWIFT and Western Union.

I build money features that reconcile: a 21-account double-entry ledger whose reports agree to the bank, server-calculated payment amounts and signed payment webhooks.

03

Leadership and community

Vice Convenor of APSU '16, my secondary-school year group's alumni association, and a trainer of new staff at Yango and Ecobank.

I also built and run the association's platform, which 263 verified members use to find each other, RSVP to events and pay dues.

04

Customer focus and communication

More than 40,000 customer inquiries resolved at Yango Ghana, with a 93% satisfaction rate, across day and night shifts.

I design for the person at the door or the treasurer at month-end, and explain technical decisions in plain English, as in these case studies.
