"Optimism is, in the first instance, a way of explaining
failure, not prophesying success. It says that there is no fundamental
barrier, no law of nature or supernatural decree, preventing progress."
- David Deutsch
I am a DevOps engineer with over 10 years of experience in the field. During my career,
I have been responsible for designing, operating, ensuring security, and ensuring compliance
for backend systems and IT infrastructure serving millions of clients at both Volkswagen and
Startnext. I have designed and operated several SaaS solutions, both on the Volkswagen
on-premise OpenStack cloud and on AWS, ensuring that these solutions not only meet technical
requirements but also legal and compliance standards.
In my previous roles, I consistently prioritized building a work culture that fosters learning and growth among
all team members. This collaborative approach extends beyond individual teams and business functions, and I
strive
to take a holistic view to understand non-technical problems. I have a strong drive for advancing the entire
organization and leverage my internal motivation for efficiency to design and implement pragmatic solutions that
meet the required objectives.
In a rapidly evolving technological landscape, I have invested heavily to stay up-to-date with modern
developments. I have worked with a wide range of technologies to orchestrate networks of Linux servers and
containers, adhering to principles such as "everything as code", "immutable infrastructure."
and a CI/CD driven workflow. In pursuit of these goals, I have frequently used tools like
Ansible, Terraform, Kubernetes, and various AWS services. For monitoring systems, I have often
employed Prometheus and Loki.
I possess extensive experience in setting up and debugging complex networking environments and have written
microservices and serverless functions in various programming languages, including Python, Go, TypeScript, and
Java.
Recently, I have developed a deep passion for the Rust programming language and actively seek opportunities to
undertake increasingly complex projects using Rust.
