Clone and modify existing iphone and android application

I need an expert individual (NOT AGENCY) in swift for IOS and/or Kotlin/Java/C++ for android. My preference goes to Russian speaking individuals. The application that is necessary to reproduce however with multiple changes and additions (not far out of scope than the current app) can be found on www.IAMSOBER.com ; the basic idea is super simple and there are code canyon code packages out there with similar "social media" type applications/platforms already prebuilt. We can definitely approach the build with that direction as well, using bits and pieces of the code to make this application quick. This project has a very tight timeframe of 4 weeks, with 2 weeks for an MVP build. Please download the free application from the website above and provide your estimated timeframe for completion along with your compensation. DO NOT RESPOND WITH GENERIC PROPOSALS - WILL BE DELETED AND BLOCKED FROM FUTURE SUBMISSION ON ANY OF MY PROJECTS.

This position and relationship is for long-term goals. This project is a test of skill and ability to work with my team.

The complete requirements documents will be provided upon agreement and signing of NDA. The project planning and framework will follow a SCRUM/KANBAN approach and have sprints. We will be using Clickup.com (invite will be sent to the team board once hired).

Thanks so much,
Art
