    By taking this job you as a firm/programmer agree to be done within the agreed upon deadline. If the work is not done by this date we 100% will cancel this job. Be 100% sure when you say a date. After accepting the deal there is no more negotiations. If this is tried, same rules apply as above. Understand the job and don't take it without asking questions before so we 100% know you understand. We will only work with users who have 95%+ finish rate and 4,5 stars+. No need contacting us otherwise. You need to test the service before giving it to us to confirm and test. When we test it, we expect 100% done work that you tried serveral times with different podcasts to be 100% sure it's correct. If we test and it's not correct, we will bill you for the programmer we will ask here in sweden for those hours it takes for him to test everything. The job: Create a backend system that automaticlly gives users a URL that podcasters can use as a pre-fix in their RSS-feed to be able to meassure statistics and analytics. The listener request pretty much bounces to us before they get sent to the place where their podcast is. To be clear, google analytics DOES NOT WORK FOR THIS. as they don't count rss-feeds correct when it's podcasts. The analytics will include 1: amount of listeners( has to be 100% accurate with [url removed, login to view] and not count wrong. We will test the service on several podcasts before verifying.) 2: Geolocation of listeners. 3: Graphs for the statistics. 4: Automated to take out average of listeners of last 3 episodes(counting 30 days after published, 3 last episodes that are 30 days old. So for example 1 episode has 100, next has 120, next has 110, the average is 330/3=110). 5: What service the listeners are using,both what sites/apps and also if it's a iphone, laptop and so on.
