Data & GIS Specialist at the Swiss Federal Office for Buildings and Logistics (BBL) in Bern, designing data architectures and integration solutions for Swiss federal real estate management.
I build solutions that bridge enterprise data management, GIS and BIM - from metadata standards to interactive visualizations. Most of my projects follow a no-framework philosophy: vanilla JavaScript and a focus on Swiss data sovereignty.
- property-inventory - Interactive GIS web application for visualizing and managing the Swiss federal real estate portfolio. Features map, list, and gallery views with Mapbox GL JS.
- transaction-immo - Property sales platform for Swiss federal real estate. Features interactive Mapbox maps, advanced filtering, gallery/list/map views, and detailed property information.
- competition-immo - Dashboard for managing and evaluating architecture competitions. Compare building project variants across sustainability criteria with interactive maps and multi-dimensional evaluation.
- workspace-management - Single-page application prototype for managing workspace infrastructure, furniture ordering, office planning, and building occupancy.
- kennwerte-db - Construction cost and FM benchmarks for Swiss federal building typologies.
- green-inventory - Interactive GIS web application for urban green space inventory, maintenance planning, and field survey operations with map interfaces.
- geo-check - Prototype web application for validating and managing property data with kanban boards, data quality rules, and interactive maps.
- kbob-fdk - Web mockup for the KBOB BIM technical data catalog featuring classifications, LOI attributes, and IFC mappings for building elements.
- ifc-viewer - A lightweight, zero-install BIM viewer for IFC files. Load models directly in your browser, inspect element properties, and export building data to Excel.
- plan-check - A validation tool for floor plan drawings. Upload, check, and ensure data quality for CAD/DWG files against Swiss Federal BBL CAD standards.
- open-docs - Lightweight, open-source document management for construction and engineering teams.
- OpenBuildings - Swiss building data made open, harmonized, and reusable. Aggregates official Swiss datasets into a consistent reference layer for analysis, integration, and practical use.
- area-estimator - Building volume and gross floor area estimation using Swiss elevation models (swissALTI3D + swissSURFACE3D) and cadastral footprints. Web app with 3D visualization and Python CLI for batch processing.
- landcover-survey - Land cover area aggregation per Swiss cadastral parcel from official survey data. Clips land cover polygons to parcel edges and calculates area distributions across 26 classifications.
- data-catalog-immo - Data catalog prototype for the Swiss Federal Office of Buildings and Logistics for documenting business objects and metadata according to DCAT-AP CH.
- ea-immo - Conceptual data model for real estate management defining core business objects in a standardized, system-independent format aligned with ISO, RICS, SIA, and KBOB standards.
- pm-cockpit - Swiss federal construction project management dashboard with interactive maps, multi-view displays, and advanced filtering.
- tender-scout - AI-powered tender matching platform for Swiss SMEs. Aggregates public contracts from SIMAP and cantonal portals with personalized recommendations.
- task-canvas - UX prototype for a project management tool with list, canvas, wiki, and analytics views.
- climate-check - Curated overview of open-source tools and methods for climate risk and carbon emission assessments in real estate, with built-in calculators, map dashboards, and PDF reporting.
- Glimpse - Single-file photo gallery viewer with folder navigation, thumbnail strip, keyboard shortcuts, and slideshow playback. Zero dependencies, fully offline-capable.
- mob-arena - Web-based arena game built with vanilla JavaScript, CSS, and HTML.
- digital-twin-rec - Digital twin demo integrating real-time face recognition with an interactive AI avatar in a split-screen browser interface.
