@ninoslavrajkovic
DevSecOps Engineer building secure cloud infrastructure and a personalized live-streaming platform, with experience across AWS and Kubernetes.
SerbiaWhat I'm looking for
At Wireless Media, I managed production infrastructure across AWS, Azure, and DigitalOcean, maintaining 99.9% uptime for production services.
I designed and maintained CI/CD pipelines with Jenkins, TeamCity, and Ansible, reducing deployment time from hours to minutes. I also orchestrated containerized microservices with Docker and Kubernetes.
At Wireless Media, I integrated OWASP ZAP and Snyk into CI pipelines to catch vulnerabilities before production, and set up monitoring with Grafana, Prometheus, Graylog, Check_Mk, and Nagios.
As a Startup Engineer at ITN Beograd, I developed a live-streaming project that lets everyone have their own personalized television, as part of a startup financed by IBM. I’m seeking a DevOps, DevSecOps, or SRE role where I can design resilient, secure infrastructure and drive operational excellence.
