What I'm looking for

I'm open to remote opportunities or relocation.

At Softswiss, I monitored production systems supporting online casino infrastructure, responded to incidents, and worked with Linux and containerized environments.

At Quantori, I maintained and supported an HPC cluster for Biogen. I worked with Slurm, managed software environments with Lmod and EasyBuild, and automated administrative tasks using Ansible, Bash, and Python.

At Luxoft, I administered the UNIX/Linux part of Gostech, a government technology platform with 1,000+ virtual machines. I automated deployments, developed Python scripts and Prometheus exporters, and supported services including Nexus OSS, Keycloak, and OpenDJ/LDAP.
