Mobile App Comment Section Feature

I need a fully-functional comment section added to my existing mobile app. All users must be able to sign in through their preferred social media account—no separate email-and-password flow is necessary. Here’s what I expect: • Clean, responsive UI that blends with the current screens. • Social login integration (Facebook, Google, Apple, or similar) hooked to the new comment module. • Create, edit, delete, and thread replies, with counts updating in real time. • Lightweight moderation tools such as basic profanity filtering and an easy way for me to hide or remove inappropriate posts. • REST or GraphQL endpoints and a small, well-documented database schema so the backend can scale. The code should slot neatly into the existing project, whether the app is in React Native, Flutter, or native Swift / Kotlin. Just outline any SDKs or libraries you plan to use before you start so I can approve them. I’ll consider the job complete when I can pull the branch, run the app on iOS and Android simulators, sign in with a social account, and post, edit, and delete comments without issues.
