Oh..let me remember… I had never worked in such big project ever. Collaborating closely with developers and working in fast pace was really really challenging. Being single man for both part ( design & front-end ) was just overload of work for me at that time :D
Here is one screenshot we send them at first:
TeliaSonera had pretty clear and strict branding guidelines that we had to care about. After few iterations, all the mockups including mobile version were approved, we were ready to move on.
Many new modules were necessary to be developed for this project. Developers started to dig in and I was responsible to deliver prototypes. SageFrame as framework helped me a lot during the development phase.
Bugs & Headache obviously goes up when we start to test in wide range of browsers and devices especially fixing stuff for all IE versions backward to IE7.
Ncell had 10 million mobile subscribers in early 2013 with daily visit more than 3k. Thus testing website in wide range of devices was essential. Finally we released bug free website in time. ;)
