As an independent mobile software engineer, I developed and published Reload Mobile for Android and iOS, supporting bill payments for electricity, airtime, mobile data, and television services.

I also developed the Methodist Hymn Book Staff application for Android, featuring staff notation. It was published on Google Play and has more than 2,000 downloads.

At eTranzact Ghana Ltd, I developed Android applications that expanded digital payment channels and worked with Java/Spring Boot APIs and external web services connected to the eTranzact Payment System.

At Vanguard Assurance Company Limited, I developed Android and iOS applications for digital insurance services, including Digital Fire Insurance and Ghana's first Digital Motor Insurance application. Earlier, I contributed Android features and backend integration to Chango at IT Consortium, and developed native mobile applications and supporting web services at Origgin Limited.
