Responsibilities & achievements

• I have been assigned to the monitoring stream. • The main purpose was to monitor the metrics and logs of infrastructure and services, update and support monitoring tools. • I’ve been participating in the development of event rules and alerts for them to notify teams and streams about any issues. • I have added the pushgateway service to send the metrics from k8s ephemeral and batch jobs to Prometheus through gateway. • I have found a way to use non-root user for all our services in ECS. • Transferred CloudWatch metrics to Prometheus to build required dashboards, wrote lots of documentation about the usage of our services for other teams. • Implemented an update-protection system with alerting rule for image that is used across all ECS/EKS services. • Worked on SLO/SLI and OKRs. • Also I have participated in the on-calls using the PagerDuty service to quickly react and solve critical issues that appeared in the infrastructure or services of our team.

Responsibilities & achievements

▪ Implemented and configured DefectDojo into existing GCP infrastructure to gather scan reports and automatically create JIRA tickets if critical results appear. ▪ Safe transfer DefectDojo from Postgresql DB for to MySQL. ▪ Developed the Security Pipeline and configured a webhook to run the scans automatically after developers commit the changes into the git-hub repository. This pipeline was running all the scanners and linters on codebases (repositories). ▪ Configured all the DAST, SAST scanners to work properly and to be able to send the reports through the DefectDojo API.
