Challenges & Solutions
#1 Challenge
Application performance in the conditions when a lot of calculations should be done

Maintaining a good performance (immediate application response to the users) when a lot of calculation should be done at the same time.

Our solution

A separate microservice with the possibility to aggregate the information from several other microservices was developed. Some calculations were developed as asynchronous + global leaderboards were moved to the cron job approach (data update 1 time in 10 minutes).

#2 Challenge
Big estimates and costs to the back-office functionalities development

Development of the custom back-office is a difficult task which can be considered as a separate project task with the estimation of 500+ hours.

Our solution

Investigated and found an open source CMS solution with which we were able to integrate in order to push application data to it. The estimation for the back-office part was reduced up to 3 times and CMS already contained basic functionalities.

#3 Challenge
Video Player Functionalities

Development of the video player functionality is 1000+ hours.

Our solution

Investigated and found about 4 potential video player vendors, had a meeting with each of them in order to understand their pricings and possibilities. Selected Azure Media player and successfully integrated in 1 week.
