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.
