+## Languages
+
+| Language | Level | Source |

+| German | Native | CV, LinkedIn |
+| English | Fluent / Professional | CV, LinkedIn |
+| Norwegian | Elementary / Basic | CV, LinkedIn |
+| Russian | Elementary / Basic | LinkedIn only |
+
+**Note:** Swisscom Zeugnis mentions French and Italian — this is likely boilerplate HR text. User confirmed: does NOT speak French or Italian professionally. Do NOT include on resume.
+
+---
+
+## Provenance Notes
+
+- **Safe to claim (full ownership):** All items listed under each position — solo developer work clearly attributed
+- **Shared/team work:** Bosch ML pipeline integration — context suggests team effort; hedge as "led" or "owned end-to-end" only if confirmed
+- **Do NOT claim:** Any results from collaborators at Fraunhofer research projects (NLP, Digital Twins) unless specific contribution confirmed
+- **RiskAhead:** Personal project framing only — not a commercial product, not peer-reviewed
+
+---
+
+## CV Variant Notes
+
+Two CV variants exist — likely tailored for different JDs:
+- **CV-1** (1 page): Leaner, adds Blockchain skills section, more AWS-specific, better for data engineering / platform roles
+- **CV-2** (2 pages): More detail on tech stack, includes Bosch PoC and RiskAhead project, has grades — better for engineering-depth or R&D-adjacent roles
+
+When generating resumes, prefer CV-1's framing for data engineering JDs, CV-2's detail depth for ML/AI or research-adjacent JDs.

+- B.Eng. field: "Applied Computer and Communication Technology" on LinkedIn vs "Information and Telecommunication Technologies" confirmed by user — use user-confirmed official name
+- Fachabitur (vocational A-levels) from Aachen — pre-university qualification; omit from resume, include on full CV if needed
+
+---
+
+## Additional Certifications (LinkedIn — not all in CV)
+

+
+## 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
+- **Tibco Spotfire** — used at Bosch (C# extensions for data analysis)
+- **UIPath RPA** — used at Generali (IT Consultant role)
+- **Camunda BPMN** — used at Generali
+- **BDD (Behaviour Driven Development)** — introduced at Generali
+- **VBA** — student assistant role (minor)
+- **PHP, PERL** — early internship (very minor)
+
+---
+
+## 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"

+- **Issuer:** Swisscom (via Credly)
+- **Issued:** February 10, 2026
+- **Expires:** February 10, 2027
+- **Type:** Internal Swisscom recognition badge — NOT an external professional certification
+
+---
+
