About
I’m Kwaku Ntim Owusu-Ansa, a full-stack mobile engineer who loves turning ideas into products people enjoy using. For over 8 years I’ve shipped apps with Flutter, native Android and iOS, and built the Node.js and Next.js services and in-house tooling behind them.
Currently, I’m a Senior Mobile Engineer at StreamTV Group, where I build a Flutter app used by more than 20K daily active users — real-time live-stream interactions, sound alerts, text-to-speech and subscriptions — along with the Next.js platform and backend that power it.
Along the way I’ve built software that reached over 1.5 million farmers in Ghana, helped health coaches in California support their clients, and connected building managers and tenants in London. I also enjoy mentoring junior engineers and building shared packages that make whole teams faster.
