To develop our new great LinkedIn Ads application, we're looking for a full-stack developer.
This is a short assignment of 3 months to build an MVP.

The aim is to produce an MVP of a Mobile (iOs) and Web app that is connected to the LinkedIn Ads campaign manager of the user and provides the ability to do the following:

1) Create audiences
2) Manage campaigns (including audience, budget, bid, duration)
3) Manage audiences
4) View Campaign groups
5) View Campaigns
6) View audiences
7) View Ad groups
8) View Ads
9) View campaign, campaign groups, audiences, ad groups, ads performance, including all available criteria (engagement criteria, performance criteria, etc.)

The App must be straightforward to use.

The application has to include the following screens at least:
1) Sign in / Sign up / Pw recovery, which can link with the user's LinkedIn Ads account through sign in with LinkedIn.
2)The App will only be available in English, will have a recurring payment fee scheme (9.99 EUR / Month / User), with a free 30 day period.

Menu items:
1) Account - Shows a screen with all LinkedIn Ads Accounts
2) Campaign groups - Shows a screen with all campaign groups
3) Campaigns - Shows a screen with all campaigns
4) Audiences - Shows a screen with audiences
5) Ads - Shows a screen with Ads
6) Changelog - Shows a multiuser changelog
7) To-do list - with the capacity to assign tasks to every user of the account

Key pages:
1) The home page will show up to 8 configurable modules and several filters (Dates, Find, Key Metrics). Each configurable module will act as a 'Starred box configuration' and will be selected as a 'Favourite' from the user on other screens.
2) Dashboard, with multi filters across the board (accounts, campaign groups, campaigns audiences, ads) and dates, so that the App shows consolidated data (for instance, for a certain period, selection of 3 audience roles + 2 company sizes + 4 accounts + 2 territories), both in one table and evolution graph. It will also integrate an 'Add to home screen/mark as favourite option) - The dashboard will also show an abstract of the To-do-list
3) Accounts screen that will show a table with the campaign group name, the account name, number of campaigns, campaign status, impressions, leads, spend, etc
4) Campaign groups screen that will show a table with the account name, number of campaigns, campaign status, impressions, leads, spend, etc
5) Campaigns screen - similar to above, by campaign, with the capacity to click on each campaign and open the audience
6) Audience screen - shows all the audience criteria for each campaign. When closed, it returns to the campaign screen. Audience criteria selection can be managed from the screen.
7) Ad screen- - shows all the ads for each campaign. When closed, it returns to the campaign screen. Ads cannot be activated/deactivated from the screen but not modified.
8) Multiuser to-do list - with the capacity of adding tasks and marking tasks as completed
9) Multiuser log screen - shows all the changes made by each user, chronologically, depending on the account, campaign groups and campaign selection

User levels:
1) Account master user, with the capacity to add users, liaised with Paypal payment bridge
2) Basic user

For users having access to more than one LinkedIn Ads account, multiple accounts have to be selected at a time- Users have to be able to click on the app logo to select accounts so that the App consolidates data across accounts.
