Krzysztof Dudek-Majeranowski

At the UK Home Office, I support critical national infrastructure across secure Linux and cloud environments. I built a Python CLI that reduced incident data retrieval time from 10 to 4 minutes and designed Kibana dashboards that cut incident diagnosis time by around 40%.

I lead structured problem-management work that contributed to a 90% reduction in recurring critical production errors, while improving documentation and L2 troubleshooting capability to reduce L3 escalations by 25%.

Previously, at Sparta Global, I built repeatable AWS and Azure infrastructure and CI/CD workflows using Jenkins, Docker, Kubernetes, Terraform and Ansible. At Risidio, I owned multi-environment Web3 deployments with no production incidents during the engagement.

I bring seven years of customer-facing management experience to technical support: clear communication, ownership, practical problem-solving and knowledge-sharing. I work well independently in distributed, asynchronous teams.
