Leads the banking squad: cross‑team communication, documented deliverables, outcomes tied to quarterly KPIs. Still ships core banking features, merged every mobile and web project into one monorepo, and owns production stability across environments.

Back at Kaoun full time, on fintech products for mobile and web.

Led major features in a React Native app, ran the release pipeline to the App Store, and mentored the freelance team that shipped the first production release.

Refactored a legacy React Native codebase. Class components moved to Hooks, with Redux and TypeScript async actions.
