Recently improved data processing performance approximately in three times (processing time decreased from 20+ to 6 minutes).
Refactored unstable, single-threaded project with complex classes (more then 2000 lines of code in class) into stable, multi-threaded, with small classes corresponding to a single responsibility principle.
Connector project written by me is using approximately by 10 internal projects which aim to collect data from different data providers, by different protocols and with different technology stacks. Here are the protocols and data formats which are commonly used in dependent projects: J-Interop, WMI, WsMan, HTTP, JSON, XML, WSDL, SNMP.
Design decisions which I'm suggesting and implementing are taking usually longer time, but theirs maintenance, extension are much simpler. Almost all my projects are covered with unit tests on 80-90%.
