Hi, I'm
Siamak Haj Azim Zanjani
DevOps Engineer
15+ years in CI/CD, DevOps, system design, and embedded systems — from FPGA to cloud infrastructure.
About Me
With 15 years of experience in programming, system design, and DevOps, I specialize in CI/CD pipelines and automation, JFrog Platform and artifact management, system design and microservices architecture, infrastructure management (VMware, Hyper-V), and embedded systems, FPGA, and PCB design.
Based in Montreal, Quebec, Canada, I currently work as a DevOps Specialist at Octasic, where I design and manage CI/CD pipelines using Jenkins, administer virtualization environments, and automate deployments with Docker. My background spans the full stack — from hardware-level development with VHDL and FPGA to modern cloud infrastructure and DevOps toolchains.
I am dedicated to streamlining development and deployment processes through CI/CD, improving time-to-market, and ensuring robust system performance. My expertise emphasizes security, compliance, and delivering reliable, scalable DevOps solutions.
Experience
- Designed, maintained, and optimized CI/CD pipelines using Jenkins, improving build reliability, reducing manual intervention, and accelerating software delivery across multiple development teams.
- Administered large-scale virtualization environments across VMware vSphere/ESXi, Hyper-V, and Proxmox VE, supporting infrastructure modernization, better resource utilization, and smoother migration planning.
- Managed and maintained self-hosted JFrog Artifactory instances, including v6-to-v7 migration, disaster recovery planning, repository cleanup, and storage optimization, helping reduce infrastructure overhead and improve artifact availability.
- Automated deployment and operational workflows using Docker, PowerShell, Bash, YAML, and Git-based automation, increasing consistency, reducing repetitive work, and minimizing deployment errors.
- Supported and improved Jenkins controller/agent infrastructure across Windows and Linux environments, resolving build bottlenecks, improving agent stability, and standardizing build execution.
- Implemented monitoring and observability using Grafana, Prometheus, and Zabbix, improving infrastructure visibility, faster issue detection, and more effective incident response.
- Managed secure credentials, service accounts, and privileged access using HashiCorp Vault and CyberArk EPM, strengthening least-privilege access, auditability, and compliance readiness.
- Contributed to source-control modernization and DevOps process improvements, including SVN-to-Git migration support, branching strategy definition, pull-request workflows, and pipeline quality gates.
- Collaborated in Agile/Kanban environments with development and infrastructure teams to improve delivery efficiency, documentation quality, operational reliability, and long-term maintainability.
DevOps Engineer
- Dockerized frontend and backend applications.
- Implemented high availability via horizontal and vertical scaling.
- Developed infrastructure as code (OpenStack).
- Implemented CI/CD pipelines for C#, VueJs, and Nginx.
- Developed a C# based multiscale custom monitoring application to continuously monitor servers and services with the ability to restart and rescale.
- Maintained 10 servers (3 physical and 7 virtual — Linux, Windows, CentOS).
- Configured Nginx as a reverse proxy, load balancer, and web server.
- Developed daily, weekly, and monthly backup scripts for SQL Database, Git Repository, and Docker Registry.
