About Me

I’m Damilola Ogunnaike, a full-stack engineer who ships production web and mobile apps. I work across React Native, React, Node.js, and Flutter.

Recent work includes TagoCash, a live fintech wallet on iOS and Android, and TagoTalk, a real-time translated calling app. Before that I built wallet systems at Juicyway and frontend products at Andela.

I fix the bugs users hit, connect the API, and keep the app stable after release.
