iOS engineer at Safaricom PLC building secure internal apps; my App Store apps exceeded 5% conversion.
KenyaWhat I'm looking for
At Safaricom PLC, I develop and maintain an internal iOS app for employee payslips, medical cover, and leave records. I implemented MSAL authentication and encryption for sensitive personal and payroll data.
As an independent iOS developer, I design, build, and ship apps for iPhone, iPad, and Mac. I improved App Store conversion above 5% through listing optimisation and onboarding work, and instrumented analytics funnels to measure user drop-off and the effect of product changes.
My shipped apps include a study planner with widgets and Live Activities, an invoicing app with StoreKit and RevenueCat subscriptions, and a contacts utility. At Roksia Ltd, I built and maintained cross-platform mobile apps in React Native.
