React/Next.js Developer Needed for Website Monetization, Mobile App Conversion, and UI Enhancements

We are looking for an experienced React/Next.js developer to enhance and monetize an existing web application. The scope includes integrating Google AdSense, Coinzilla, and Bitmedia ad networks, optimizing ad placements for web and mobile, improving UI/UX, responsiveness, performance, SEO, and overall user engagement. The developer should also convert the existing React/Next.js application into an Android APK (preferably using Capacitor), prepare it for future iOS deployment, integrate Google AdMob for mobile monetization, and implement OneSignal push notifications for both web and mobile platforms. Experience with modern dashboards, charts, mobile app development, and scalable production-ready applications is preferred.
