CHALLENGES
Our main goal was optimization. The previous iteration of the website contained various pages with different and complex structures. Pages performed multiple functions and held data used by several components of the system. That fact added difficulty to finding optimal UI-solutions.

It was also vital for us to make the website capable of loading a large number of simultaneous users. Speaking about the mobile version, a core issue requires validating data and conducting complex calculations.
