Services
Four fields that interlock in everyday project work. Each can be commissioned on its own — together they are worth more.
Web development
Applications that make research data visible and usable
From a project website to a specialist application: interactive maps, edition portals, data catalogues and tools that solve exactly one problem in everyday project work. Built on the formats and interfaces the humanities already rely on — TEI, IIIF, SPARQL, Wikibase — so your data stays interoperable.
What this covers
- Project and institutional websites
- Interactive maps, timelines and network graphics
- Search and catalogue interfaces for large collections
- Wikibase and SPARQL applications
- Digital editions using TEI
- Accessible implementation to WCAG 2.2 AA

UI/UX design
Ordering complex data so non-specialists can follow it
Humanities data is rarely flat: nested hierarchies, uncertain dating, competing readings. Good design does not flatten that complexity but guides people through it. Drafts come early and get tested with the people who will use them.
What this covers
- Information architecture for large collections
- Wireframes and clickable prototypes
- Data visualisation with justified choice of form
- Layout grids, typography and colour systems
- Accessibility considered from the start
- Multilingual interfaces

Hosting & operations
Dependable operation on servers in Germany
Funding periods end; websites are meant to stay. I operate applications on my own infrastructure in German data centres — with backups, maintained certificates and updates. On request, this also covers applications built elsewhere that now need someone to look after them.
What this covers
- Operation on servers in Germany, GDPR-compliant
- TLS certificates with automatic renewal
- Regular backups and restore testing
- Domain and DNS management
- Security updates and monitoring
- Taking over existing applications

Research data management
So that data outlasts the project
Data management plans, clean modelling, authority files and the route into a repository: what funders require today and what actually makes data reusable are related but not identical questions. I help with both — from the application stage to final deposit.
What this covers
- Data management plans for DFG and BMBF proposals
- Data modelling along FAIR principles
- Authority files: GND, Wikidata, FactGrid, GeoNames
- Record linkage and reconciliation of large collections
- Migration, cleaning and format conversion
- Handover to repositories and long-term archives

How we work together
No rigid process model, but a dependable framework — particularly where funding cycles and reporting duties set the rhythm.
Conversation
You describe the plan, the timeframe and the constraints. I say what I consider feasible — and what I would advise against.
Proposal
A written proposal with a clear scope and either a fixed price or a day rate, matched to how your funding is administered.
Implementation
Development in manageable steps with results visible early. You watch progress rather than wait for it.
Handover
Source code, documentation and data go to you, in open formats and with no lock-in. I am glad to keep operating and maintaining it, but you are not obliged to let me.
