## LinkedIn Summary / Headline (for cover letter framing)

**Headline:** Staff DevOps & Data Engineer

**Summary (user-authored — useful for tone/framing):**
> "Passionate about building the infrastructure that powers Data and AI. With a background in Computer Engineering and over 8 years of hands-on experience, I specialize in designing scalable ML Infrastructure and automated data pipelines. I thrive at the intersection of Software Engineering and Operations. Whether it is deploying containerized inference models on Kubernetes or orchestrating event-driven architectures with Kafka and AWS, I focus on automation and reliability. My recent work involves re-architecting monolithic data processes into agile, serverless microservices."

**Key themes from summary:**
- ML Infrastructure + automated pipelines
- Software Engineering ∩ Operations
- Containerized inference (K8s)
- Event-driven architecture (Kafka, AWS)
- Automation and reliability
- Monolith → serverless/microservices migration

## Provenance Notes

- **Bundeswehr / Military:** Verifiable leadership background — frame carefully; don't imply technical work
- **Capgemini:** Short tenure (7 months) — use hedged framing if included at all; zeugnis will confirm scope
- **LinkedIn certs:** IBM AI Engineering Specialization sub-courses are individual Coursera courses; on resume list the specialization, not individual sub-courses
- **RPA/Camunda at Generali:** Real hands-on PoC work — can claim "implemented BDD pipeline" and "RPA automation with UIPath/Camunda"
