MedicFlow
Healthcare workflows running directly on dedicated POS hardware.
Outpatient and inpatient billing for Oyo State hospitals, on the same POS terminals that print the bill and take payment.

Experience
SurgePayFrontend Engineer, fintech
I built the multi-currency mobile app end to end: virtual card management, payment and remittance flows, and real-time transaction updates, shipped to Google Play and the App Store. The flows I built moved over $1M in transaction volume in the first six months, and SurgePay went on to secure six-figure backing from the Stellar Community Fund.

AFT Solutions LimitedMobile Engineer, government
I build the field applications behind Oyo State enforcement, revenue and healthcare: OYRTMA, OYO-VIO and the MedicFlow hospital records system, plus E-Haulage, Park n’ Pay, OYO-BMS and OYO-SSS. Most of them run on dedicated Android POS terminals with card payments and receipt printing. Together these systems have processed more than ₦6B in payments.

Engineering notes
Some of the most interesting mobile problems begin after the UI is finished.
Printing images across Android app boundaries on POS hardware
The POS printer wanted a file path, and the file lived in a sandbox the printing app could not see.
Using Expo OTA updates on POS terminals
I had been rebuilding and reinstalling APKs for every change. The terminals only needed a new JavaScript bundle.
When a POS has a camera but no camera app
launchCameraAsync worked on my phone and failed on every new terminal. The hardware was there; the app to handle the intent was not.
About
I turn product ideas and operational workflows into software people rely on, from the first screen to the store listing and the device in someone’s hand.
I started on web platforms, moved into mobile, and now spend much of my time where apps meet hardware, networks and app-store rules.
