Fixing Dating website Node.js & PostgreSQL

Hi, looking for a talented freelance developer for my dating website that was written in node.js & PostgreSQL. Looking for someone for the long run, to fix bugs and to add additional features upon request. Please read carefully the details below: AWS hosting - now the system use aws server to host all the images that was uploaded by users, I want to change the logic, instead of amazon for upload picture, implement another server for pictures upload and serve pictures. 100 credits per registration instead of 0 - add the option in admin panel to set the credits that user is getting upon registration. credits system already implemented, just need the option to set via admin how many credits per registration. When credits = 0 or you don't have enough credits per the needed action (kiss, gif, gift) show popup for purchasing the credits, popup already implemented, just need to call the popup and show it to user when he doesn't have enough credits. Buy coins - integration to PayPal and to additional payment solution, now PayPal is already implemented, just need to check and test and integrate an additional payment solution. Fix serval bugs on gif system (giphy) - Giphy system already implemented, need to set by default the search keyword that will be open upon clicking gif button(like: "love") Emojis- load very slow, should be optimized to show emoji faster than now. Email templates - send user an email upon registration, upon new msg, forgot password, upon someone new who visit his profile, getting new gift etc. - we want the option to edit those templates via admin panel and we need an integration with send grid. Other confidential bug fixing that will be sent via private communication after signing confidentiality agreement.
