Front end android project

Dear All, I am looking for android developer who knows Kotlin and rxkotlin. I have a pre excisiting application which i wrote in android using java. now i want to re-write it in kotlin to release an update version. the app currently in the play store as "shlondryApp" the application is currently calling my web service which i wrote in php. i wrote another better web service in java using rest api. so i you need to link the updated version to my new web service. so what you have to do is to only make the front end android side for me. I will provide detailed instruction how to handle the button clicks or Activities. The application is not hard yet very easy, just simple POST http requests to my server and parse the response as JSON, then present the data. please check the current version of the app in play store from this link: [login to view URL] the update version, will has login/signup/forgot password/account activation/comment like/comment dislike/comment report as spam/comment reply/seeing comment reply list/admin side login/admin side to see comment added by user to reject or approve/same for professors, majors,feedback,and university. / arabic version and english notification integration to firebase and crashlist (admob already integrated) every thing will be provided, even the logic and how to listen to button click. i would love to see rxkotlin (reactive programming) if possible if you want to make an offer of the above but coded in java let me know. the current version already in java. i will provide the old code if needed. i will provided detailed documentation on the requirement.
