I am supporting the building of multiple software solutions that added - and will continue to add - a great feature set to the e-commerce platform and improved it. I ensure that best practices are followed and am a consultant for technical and non-technical inquiries regarding cloud infrastructure, software architecture, and many other topics such as continuous integration and continuous deployment. Additionally, between many other topics, I make sure that, for example, as much CI/CD and IaC code as possible is reusable and available for use by the entire department. In addition, I take over tasks from my previous position, develop proof of concepts, try out new technologies for HORNBACH and establish business processes from them.

• Accompany software projects that need to be integrated into a uniform landscape.
• In-house consultant for technical and non-technical inquiries about public cloud and software architecture.
• Ensure that as many technical processes as possible are standardized and reusable to accelerate many parallel projects.
• Derive and implement cross-project standards from project-specific implementations.

I contributed to building a multi-tenant public cloud infrastructure to run a microservice-based e-commerce platform. I actively participated in the migration of the platform. Continuous improvement of the platform was part of my daily work. In addition, I planned and implemented the complete architecture of a system in line with the latest standards with regard to the technologies used, security and cost efficiency and made it stagable in the shortest possible time. In addition, one of my daily activities was to drive forward the automation of cloud platforms using the latest enterprise tools. For this I have developed a company-wide library that enables a uniform process for any public cloud deployment.

• Planning, design and implementation of cloud-native architectures.
• In-house consultant for the development departments on public and private cloud issues.
• Managing Infrastructure-as-Code with Terraform, Ansible and Packer, all deployed automatically.

During my practical semester, I implemented PostgreSQL backups, failover and recovery tactics and automatisms. I extensively documented the implementations and utilized containers and Kubernetes for it. For my bachelor thesis, I worked on developing, implementing and automating Chaos Engineering practices for a microservice-based e-commerce platform.

• Implementing automatic PostgreSQL backups, failover and recovery tactics.
• Developing and implementing Chaos Engineering principles and experiments.
