Cross-Platform Social Networking App: Adjustments, Launch, and SEO Support

I'm seeking an experienced mobile app developer to finalize and optimize my cross-platform social networking app. The app is written in JavaScript and already live on Apple but requires adjustments before re-uploading with a corrected description. Tasks include connecting the invite link to the download option, enabling users to report inappropriate pictures, guiding me on managing images via Supabase, fixing typos, adjusting pop-ups, ensuring email collection functionality, and launching on Google Play. Additionally, I need professional guidance for SEO optimization and promotion post-launch.
