I am a Senior Research Software Engineer and Architect bridging the gap between Classical Studies and advanced Data Engineering.
As my work focuses on long-term institutional infrastructure, most of my contributions happen within organizations rather than on this personal profile.
- Maintainer & Lead Architect for Imagines Nummorum (Graph-based Image Semantics, 2025–2050).
- Admin/DevOp for the TELOTA DH working group at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW). Focus: Infrastructure management, deployment, and system architecture.
My work is rooted in a deep dual background:
- Humanities: Trained Classical Archaeologist, Ancient Historian, and Philologist.
- Engineering: Specialist in SQL, PHP Laravel, Vue JS, Graph Databases (Neo4j), Knowledge Graphs, and Sustainable RSE.
- Imagines Nummorum: 25-year initiative building an iconographic Thesaurus of Ancient Greek Numismatics.
- Coprus Nummorum: Backend and internal Editor Frontend for Corpus Nummorum
- Patristic Text Archive: Frontend engineering and reader development for biblical and patristic corpora.
- Epigraphy & Digital Editions: Technical infrastructure for CIL (Corpus Inscriptionum Latinarum) and IG (Inscriptiones Graecae).
