Profile
I work mostly with automation, and my approach is to "automate everything that can be automated". When the right tool does not exist yet, I build it. When an existing tool does not quite fit, I improve it.
In the enterprise world, my main platform is mainframe z/OS. I work on infrastructure automation and monitoring, and connect z/OS with the rest of IT, such as Azure DevOps and ServiceNow.
Outside of the enterprise, I have run Linux services (Debian, NixOS) for small teams for several years: Git forges, CI/CD pipelines, authentication, networking and more.
Because I work in both worlds, I like to bring modern practices to the mainframe. I encourage people to use newer technologies such as Python, Git, VS Code or Ansible with z/OS where they make sense. I already use them in my own work, and they make it faster and more reliable.
I work on the planning as well as the delivery. I lead brainstorming sessions to find the best-fitting solution, then work out how to implement and integrate it.
Experience
Senior Lead, System Administration · Kyndryl Hungary
I support and develop automation for ABN AMRO Bank through Kyndryl Hungary. My focus is still automation, but it now covers business applications as well as infrastructure.
