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
Updated Skills (additions vs. CV)
- PySpark — confirmed at Swisscom Staff level

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"
