I build spatial intelligence for decisions about sites and neighbourhoods. At TJX Europe, I delivered European location analysis and automated site-selection, catchment and cannibalisation workflows. I also connect environmental research to public maps and develop spatial data products.

CityLoops: Urban Circularity AssessmentCompleted researchBuildings coloured by estimated total material stock, in tonnes: pale yellow lowest, dark teal highest. Apeldoorn material-stock map, 2022. Map: Gerardo Ezequiel Martín Carreño. Buildings: 3DBAG; material intensities: Sprecher and colleagues. Basemap: CARTO and OpenStreetMap contributors. Screenshot: 11 October 2026.
A co-authored method and maps estimating material stored in buildings.
Scope and limitsThe method and maps estimate urban flows and stocks from available evidence; they do not audit every tonne or survey the materials in each building. The Apeldoorn map credits 3DBAG building data and material intensities from Sprecher and colleagues. The two maps do not establish delivery of every proposed dashboard across all five pilots.
My contribution and scope
At Metabolism of Cities, I co-developed and co-authored D4.4, the Urban Circularity Assessment Method, as one of four named authors. We combined material-flow accounts for two reference years with bottom-up building-stock accounting and 18 indicators. The method specified Sankey and dashboard outputs for facilitated application in Apeldoorn, Bodø, Mikkeli, Porto and Seville. I also developed CARTO maps of building material-stock estimates for Apeldoorn and Bodø, making the stock analysis explorable at building scale. I supported application across the five pilots, built Sankey and CARTO outputs and managed two analysts.
A co-authored cartography method for nine European pilot cities, connecting local skills, materials and community networks.
Scope and limitsD2.2 documents the 2021–2022 alpha scope. The public website has evolved since then and includes later pilot material produced by the wider programme. “Urban ecosystem” refers to resources, infrastructure and social relationships, rather than a biodiversity survey.
My contribution and scope
At Metabolic, I co-authored D2.2, the Cartography Alpha Version, as one of six named authors. I helped shape a method connecting geographic context, community mapping and material flows. The report documents a clickable three-page website mock-up using Amsterdam as its example, alongside KUMU maps.
An open-data proof of concept, a technical roadmap and spatial validation controls for the founding team.
Scope and limitsThe engagement ended in October 2026. This case describes my delivered technical work, not ownership or proven customer impact. Detailed architecture and results remain confidential. Predictive signals do not establish causal effects.
My contribution and scope
As fractional CTO, I began with a technical audit and turned its findings into a staged implementation roadmap. I set technical strategy, designed the solution and data architecture, and led data engineering, bespoke spatial modelling and software delivery. The open-data proof of concept explored audience geography, location choices and media allocation. I introduced source and licence records, spatial holdouts, baseline comparisons and reproducible release checks, keeping customer-specific validation separate.
An atlas and poster maker for turning maps south-up and questioning how the world is drawn.
Scope and limitsAn artistic and educational tool, not a neutral representation of the world. Changing orientation does not remove projection distortion. The Tissot overlay makes that distortion visible.
My contribution and scope
I built the interactive mapper, projection controls and poster-making workflow. The interface connects north-up and south-up views with styling, editable text and print formats. I developed a visual language drawn from spot-colour printing, so the same cartographic idea can be explored in the browser and taken away as a poster.
