What I'm looking for

I seek roles where I can apply automation and observability to improve network reliability, work with cloud-native tooling, and continue growing in infrastructure and security-focused engineering.

I am a DevOps and network engineer with strong fundamentals across networking, systems and automation, experienced in designing and operating high-availability networks and deploying scalable infrastructure using IaC, containers and orchestration. I have delivered Layer 2/Layer 3 connectivity solutions, implemented advanced monitoring with Prometheus/Grafana, and automated network tasks with Python, PyATS and Ansible.

I bring practical hands-on experience across multi-vendor environments (Cisco, Juniper, Fortinet, MikroTik), virtualization (Proxmox, VMware), containerization (Docker, Kubernetes), and CI/CD pipelines (GitLab). I am committed to continuous learning in cybersecurity and low-level programming, and I aim to apply automation and observability to improve reliability and operational efficiency.
