Projects
Highload Data Validation System
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.

Solution supposed to get tickets from information system customers.

architecture with reusable components to get it done faster.
