David works across the Case Law Explorer estate: corpus-specific ingestion, a shared legal-data schema, bounded search and graph APIs, optional identity and access policy, the SvelteKit research interface, and the Docker/Coolify operations plane. His accepted ICAIL 2026 work with Gijs van Dijck adds a reproducible comparison of centrality methods for European human-rights citation networks.
LimitsThe public record establishes the system boundaries, contribution scope, and accepted publication state. It does not claim sole authorship of the datasets or research programme, and the paper has no DOI until final proceedings publication.
Hayeren joins an Eastern Armenian course, grammar, an inflection-aware dictionary, inspectable reading, review, tutoring, notebooks, classrooms, and native clients around a shared learning model. Mobility in Change carries one client journey across Italian, English, German, and French while preserving the visitor’s route and keeping generated translations in review before publication.
SynthesisTogether, the two systems show multilingual work at different layers: Hayeren models language itself, while Mobility in Change governs localized client content and navigation.
Commonfold is a private knowledge system where capture is reviewed before write, keyword and vector retrieval preserve routes back to their sources, and Postgres remains canonical while Markdown stays portable. The Case Law Explorer work applies a separate retrieval architecture to public legal corpora through bounded API and interface layers.
SynthesisThe repeated design decision is attributable retrieval: generated or searched output must remain connected to inspectable source records and explicit system boundaries.
For Mobility in Change, David designed the information architecture, visual system, four-locale public experience, and qualified inquiry journey, then implemented the production platform and authenticated client editing workspace. The maintained system includes route-preserving language switching, responsive media with reduced-motion and data-saving fallbacks, reviewed translations, revision history, and named media slots.
LimitsThe public source confirms the delivered platform and current maintenance state. It does not publish private inquiries, administration data, or commercial performance figures.
The Armenia atlas is a public-history prototype connecting places, sources, chronology, and authored context. The West Bank atlas organizes documentary fieldwork into a structured place record while separating processed public derivatives from the private source archive and retaining rights, consent, and sensitivity metadata.
SynthesisBoth projects use maps as reading infrastructure rather than as collections of isolated pins: place remains connected to sources, chronology, and editorial context.
David works across legal-data services, reproducible research, multilingual product infrastructure, retrieval systems, client publishing, and source-aware mapping. The strongest fit is research software involving complex data, reproducible methods, multilingual interfaces, or service boundaries.
SynthesisThe strongest fit is where product implementation and research infrastructure have to be designed together.
