At Mouv Africa, I ship features for a Kotlin Multiplatform marketplace app, sharing business logic across Android and iOS. I built a payment strategy and factory system for M-Pesa STK push and PayPal, with socket-based confirmation as the sole automatic payment channel.
I also designed a WebSocket event bus using Kotlin SharedFlow and implemented cross-platform location services for nearby listings. On my Mwenyeji commuter app project, I built an Android app for Nairobi commuters and took it from problem framing through Play Store submission and closed beta.
