Cross-Platform Social Networking App Development

I'm looking to create a mobile app that focuses on social networking. This app needs to be developed for both iOS and Android platforms.

Key Aspects:
- Expertise in cross-platform mobile app development is a must.
- Prior experience in developing apps is mandatory.
- Proficiency in understanding and implementing social networking features such as user profiles, friend requests, messaging, news feeds, etc.
- Knowledge of UI/UX principles to ensure the app is user-friendly and visually appealing.
- Ability to ensure the app is scalable and can support a growing user base.
- Understanding of security measures to protect user data and privacy.
- The idea of the app has too much complexity and need attention to detail .
- Preferred location Bangalore so that we can connect offline as well , but other location also applicable cause skill is the highlight .
- wanna work in a collaborative space , open for your suggestions as well but need to prioritise and deliver what we want.
