Senior software engineer specializing in cloud infrastructure, automation, and SAP integration.
GermanyWhat I'm looking for
I am a senior software engineer focused on cloud infrastructure, automation, and SAP-based integrations with a strong background in Python and JavaScript. I combine hands-on engineering with operational responsibility, having run OpenStack and AWS environments and supported development teams.
At Alter Solutions I operate and advance a central SSO application in AWS, manage OpenStack infrastructures with Terraform, and deliver automation scripts for migrations and maintenance. I also act as deputy team lead, assisting with task coordination and support handling.
Previously I developed order-management systems and customer service prototypes, and led SAP implementation projects where I owned technical development, interfaces, and client-facing support. I emphasize code quality, maintainability, and collaboration with functional stakeholders.
I hold multiple AWS and Terraform certifications and a B.Sc. in Computer Science, and I look for roles where I can apply infrastructure automation, cloud operations, and SAP integration skills to deliver reliable, scalable systems.
