Experience

Built from the network up.

My path started with physical networks and datacenters, then expanded into Linux, automation, delivery platforms and reliability engineering.

  1. GreenWeb

    DevOps Engineer

    • Operated Kubernetes environments using kubeadm, Kubespray, RKE2, Rancher and Harvester.
    • Worked with Ceph storage, CI/CD delivery, access security and infrastructure automation.
    • Improved monitoring coverage across more than 25 servers and 100 services.

  2. Forvest

    DevOps Engineer

    • Operate cloud servers, networks, backups, delivery pipelines and production observability.
    • Standardized Docker build, registry push and stage/production delivery through reusable GitLab CI templates across backend, frontend and gateway services.
    • Maintain shared observability and deployment tooling across multiple product lines.

  3. Part Software Group

    DevOps Engineer

    • Improved release safety through CI/CD, production monitoring and closer development–operations workflows.
    • Reduced incident detection and resolution time from approximately 24 hours to 2 hours.

  4. FAVA Astan Quds Razavi

    DevOps & Infrastructure Engineer

    • Administered Linux, VCSA, physical datacenter and office-automation servers.
    • Monitored 15+ physical servers, 350 virtual machines, 90 routers and 40 Cisco switches.

  5. Radar Fartak Hooshmand

    Network & Infrastructure Engineer

    • Supported network systems, virtual infrastructure and organizational connectivity.
    • Monitored internal services and delivered network and surveillance infrastructure.

Network engineering foundation

Before cloud-native, I built the networks underneath it.

My infrastructure path began in 2012 with hands-on network delivery. Across more than 100 engagements, I worked from passive infrastructure and fiber to routing, wireless, virtualization and production operations.

01 / CONNECTIVITY

Enterprise networks

TCP/IP, routing, switching, MikroTik, Cisco, structured cabling, wireless design, mesh networks and point-to-point connectivity.

02 / INFRASTRUCTURE

Fiber, voice & physical systems

Fiber backbones, passive and active network delivery, VoIP, surveillance networks and resilient connectivity for factories, offices and hospitality sites.

03 / OPERATIONS

Systems & virtualization

Linux, VMware ESXi, VCSA, Proxmox, server operations, monitoring, backup planning and troubleshooting across physical and virtual estates.

Rasa IT

Technical & Operations Manager—network design, cabling, systems procurement, internet services and field delivery.

Microcom Engineering Group

IT & Network Manager—network scenarios, device configuration, technical support, surveillance systems and training.

100+ network and IT engagements

Included fiber-backed industrial sites, a 350-node wireless POS network, hotel mesh networking, VoIP infrastructure and campus network overhauls.

Core expertise

A broad foundation, applied with operational focus.

I work best where infrastructure, software delivery and real production constraints meet.

01 / SYSTEMS

Linux & networking

Linux administration, TCP/IP, routing, switching, DNS, reverse proxies, load balancing and production troubleshooting.

02 / PLATFORM

Containers & Kubernetes

Docker, Kubernetes, RKE2, Rancher, Harvester, kubeadm, Kubespray and Ceph-backed environments.

03 / DELIVERY

CI/CD & automation

Reusable GitLab CI templates, Docker build and registry workflows, Bash, Ansible and SaltStack across multi-service products.

04 / SIGNALS

Observability

Prometheus, Grafana, Zabbix, Elastic, Graylog and Splunk for actionable metrics, logs and operational visibility.

05 / FOUNDATION

Virtualization & storage

VMware ESXi, vCenter, Proxmox, Harvester, Ceph, object storage, backup integrity and recovery planning.

06 / CLOUD

Hybrid infrastructure

Production experience across on-prem systems, Hetzner, Iranian cloud providers and selected AWS workloads.

How I work

Reliability is a design decision.

Good operations should make delivery safer, incidents easier to understand and routine work less dependent on heroics.

01

Make it observable

Useful telemetry should explain what changed, who is affected and where investigation should begin.

02

Automate repeatable work

Automation earns its place when it reduces risk, shortens feedback loops and remains understandable to the team.

03

Design for recovery

Backups, runbooks and failure boundaries matter as much as a successful deployment.
