Description
The solution supposed to validate XML messages from 5 different sport data services. There were screens to set up validation rules, rules consisted of different operators and AND, OR logic. We had challenges with performance, because maximum loading was 750,000 messages per minute. We created different applications, some of them were downloading XML files, other ones were validation them and were working in parallel. The solution also contained screens with statistics charts and XML messages with the wrong data.

Description
Solution supposed to get tickets from information system customers. It was able to create rules to assign tickets to appropriate departments based on different conditions: priority, product, issue type, etc. The system had customisable ticket forms with custom fields of 7 different types. Timeline for the project was very tight, basically we had 3 months to get system implemented. Because of that we had to create solid
architecture with reusable components to get it done faster.
