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.

• ORCID: 0000-0003-2713-5207
• Mastodon: @[email protected]

Finalizing the publication draft and a technical demonstration for our Property Graph Model (v0.9).

Key Focus Areas:

• Formal Description of Compositional Data: Modeling the complex semantic relationships within ancient imagery.

The public release of the core schema and the tech demo is scheduled for January 2026.
