Yusuf Oezeren

I’m part of the Developer Productivity team, focusing on tools, automations, and platform solutions to help developers work more efficiently. I improve CI/CD pipelines, streamline infrastructure, and support system integrations to reduce friction. I work with Ansible/AWX, GitLab, Docker, and HashiCorp Nomad, while continuously learning and applying modern infrastructure practices to make developer workflows smoother, faster, and more reliable.
