Portfolio
Administrative portal for images processing service using YOLO. It is created to identify an access to the restricted area. The portal is used to check the Data Warehouse cleanup including statistics on number of video files that were deleted, storage details, etc.
Release management portal is used to identify release gaps, testing reports and to collaborate with the team on fixing release issues. As a lead developer I need information about my product quality and release gaps to plan my activities of deploying new version of products. Data is stored in different systems like Jira, Jenkins, Artifactory, external documents. It is hard to compile all these data to some kind of decision without great mental work. My team have created a release dashboard to control the quality of each artifact that is being deployed to production.
Poligon is a distributed system for collecting security objects and testing these objects on different environments, checking exploits and patches for them. The System is integrated with vCenter to start\stop\create VMs and to test exploits and patches.
