## Performance Rating (German Zeugnis Decode)

| Phrase | Interpretation |
|--------|---------------|
| "stets zu unserer vollen Zufriedenheit erledigt" | "gut" tier (second of five) — solid, not top-coded |
| "Erwartungen in jeder Hinsicht gut entsprochen" | Met expectations in every respect |
| "überdurchschnittliche Arbeitsqualität" | Above-average quality |
| "absolut selbständige Arbeitsweise" | Fully independent working style — strong signal |
| "äußerst umfangreiches und fundiertes Fachwissen" | Extremely extensive and sound expertise |
| "hohe Zielorientierung und Systematik" | High goal-orientation and systematic approach |
| "persönliches Verhalten war immer einwandfrei" | Conduct flawless |
| "in jeder Hinsicht erfolgreichen Leistungen" | Successful in every respect (positive close) |

**Overall grade: gut (good) — strong Zeugnis for a research role.** Rating is one tier below Bosch. "Vollen" (not "vollsten") Zufriedenheit is the formal "gut" signal in German Zeugnis coding. Context: research positions typically use slightly more reserved language.

## Resume/CV Bullet Seeds (Fraunhofer position)

1. Developed speech recognition + ML pipeline for ARTUS, an automatic sea rescue transcription system — first application of NLP in Fraunhofer CML's maritime safety domain
2. Built microservice architecture for MISSION maritime data exchange platform using Docker, Express.js, and SQLite
3. Established CI/CD pipeline for SCEDAS® crew scheduling software via Jenkins; automated build and deployment process
4. Contributed to ML-based research grant proposal for predictive maintenance timing in maritime operations
5. Developed and maintained SCEDAS® application features in C#, Entity Framework, and SQL Server

## Provenance Notes

- **ARTUS and MISSION** are named research projects — safe to cite by name
- **Speech recognition / ML** — "Entwicklungstätigkeiten" = development work; use hedged verb ("Contributed to" or "Developed components for") as this was research team work, not sole development
- **SCEDAS® CI/CD** — explicitly listed as his task; full ownership verb appropriate (Established, Configured)
- **Research grant proposal** — "Mitarbeit" = contributed; use "Contributed to" not "Led"
- **Fixed-term contract** — normal for research positions; no need to note on resume
