Experience
Xing Build
Security was embedded through static application security testing (SAST)
and dynamic application security testing (DAST) tools integrated into CI/CD pipelines. Ansible automated infrastructure, NexusIQ ensured secure artifact management, and Jenkins optimized CI/CD pipelines with caching and parallel testing. We leveraged Prometheus, Grafana, and OpenTelemetry to enable real-time monitoring, centralized logging, and distributed tracing. This approach enhanced scalability, uptime, and vulnerability reduction while ensuring end-to-end visibility and compliance.
