Working @ ActualSales, building landing pages for internet marketing campaigns.
Responsible for developing dozens and dozens of Landing Pages.
All Landing Pages, have Front-End and Back-End components. Some had other features like Web Services and integration with certain APIs. All development had to be made under tight schedules, I mean really tight schedules. The Front-End must be cross-browser. The Back-End consisted of integration with a campaign management platform that tracks all kinds of things (clicks, conversions, etc...).
Besides that, certain landing pages had CRM integration where the client could view the campaign data.
