As a freelance professional specializing in infrastructure and delivery pipelines, my work focuses on elevating small businesses through sophisticated automation and environment development. My competencies lie in continuous integration and deployment (CI/CD), infrastructure as code (IaaC), and cloud services, leveraging tools like Terraform, Ansible, and cloud platforms such as Google and AWS. At IBM, my contributions to the reliability and secrets management teams have honed my skills in performance testing and operational improvements. Collaborating with diverse teams, we have enhanced our chaos testing framework and integrated monitoring solutions, such as Prometheus and Grafana, to ensure high system reliability and proactive issue resolution.

BarclaysDevOps Technical Lead

Jun. 2020 - Nov. 2020Prague, Czechia• As a member of the Compliance team, I unified CI pipelines and improved the toolchain's technological footprint. He worked closely with the dev team and addressed the pain points while ensuring good code quality and standard practices followed across the board. • With the dev team's help, I’ve provided a single job template, and re-factored all build pipelines into simple configurations derived from it. He also succeeded with the next stage and on-boarded SonarQube and Veracode as mandatory steps across all projects. He finished everything with full integration between VCS and CI server, which become the enabler for enforcing standard code practices further. • Regardless of the "follow the sun" alignment, I worked with other DevOps fellows from different geographical areas and helped them get up to speed with the technologies used. He inspired them to follow the best practices and mentored less senior team members whenever he saw it fit.
