Complete & test Ruby on Rails app

I made an incomplete application in RoR4 about rating called Feedbacks. Application works but, test coverage is not complete and I need a support to find & fix bugs and improve the code. It's based on 3 models: Shops ( Name, Description, Address, City, ZIP, State, Email, Phone, Photo_URL, URL) Userfeedback (User_id, Shop_id, Title, Comment, Rating, Pros, Cons) Users (Username, Image_URL, Name, Surname, Address, City, ZIP, State, Email, Phone) unfortunately due to lack of time, I need a prof to cover some tasks divided in 3 different stages. I'd like assign just the first stage at the moment, after the result, I'm going to go ahead with the next stages Requirements: - proven excellent RoR skills: test and fix bugs is the primary goal, but I want to improve also the quality of the code - knoledge of the following gems : Capybara, factorygirls, Devise, Datatable, Will_Paginate, Bootstrap - Even if the first stage is not time attack, I'd like to close Stage1 in a month - Possibly able to go ahead with the next stages (so IOS and Android programming are appreciated) Stage1 Task1: Test & QA Check all code and improve where possible Remove bugs and security bugs Fix and complete missing TDO (models, integration, functional, routes) test scenario Test applcation by automatic & manual tests and fix any error Task2: Add functionalities On shop and user creates combo boxes to fill-in State, City and Zip code Add Facebook Authentication Stage for the next future: Stage2 Task1: Create Admin interface (Admin role in Devise) Task2: Internationalization the whole site Stage3 Task1: Create Android application Task2: Create IOS Application
