Matrimonial App Creation & Backend Development with Deployment

I'm seeking a seasoned Android app developer with a robust background in backend development(only backend developer can also bid its a long term project and will give profit percentage as well), to design and develop an engaging matrimonial app. Key Features: - User profiles: Each user should be able to create a comprehensive profile with personal details. - Search and filter options: Implementation of robust search and filter options to shortlist potential matches. - Private messaging and chat: Users should be able to contact each other privately via messaging and chat. - Connection requests: Users should be able to send and respond to connection requests. - Comparable functionality: I am seeking a product encompassing all the features recognised in popular matrimonial platforms such as [login to view URL] and Sangam.com. -Searching and matchmaking algorithm Design Preferences: I am leaning towards a professional and clean design style that is user-friendly and easy on the eyes. Ideal Skills: - Exceptional Android development experience. - Proven track record in backend development. - Prior experience in matrimonial/social networking app development. - Solid understanding of clean, professional design concepts. Points to note - 1. Android app Code should be in Kotlin with MVVM architecture and modular packaging. 2. Backend should use an SQL or relational database with REST APIs so we can later query on it, also backend should be able to handle Images of the users with scalability is must. 3. Security for backend- since it would contain user confidential data. 4. Design can be normal but just keep it clean with something in blue theme I will get it updated later on from you once I have designer. 5. Support on deployment of backend to web services like Azure/Amazon. 6. Also to deploy 3 environments, DEV, QA, Prod. My budget is tight but I am willing to give some profit percentage from the revenue for next 3 years can discuss on it later, so looking for someone for long term commitment. Also right now I am not looking for a website for this but later on It will also come. Please drop your bids.
