Gerardo Ezequiel Martín Carreño

Fractional Chief Technology Officer

CommunityAI, London

Started with a technical audit and implementation roadmap, then led solution architecture, data engineering, bespoke spatial modelling and software delivery for an early-stage community-intelligence proof of concept. Set technical strategy and introduced provenance, licence governance, spatial validation and reproducible release controls for location-intelligence and media-optimisation questions.

Full-Stack Spatial Data Scientist

TJX Europe, London

Delivered geospatial analysis for European markets and built cloud-native workflows connecting loyalty, footfall and demographic evidence. Automated site-selection, catchment and cannibalisation analysis that had required weeks of manual work, and presented the work at the Spatial Data Science Conference 2025.

Researcher and Spatial Data Analyst

Metabolism of Cities · Horizon 2020 CityLoops, from London

Co-developed and co-authored CityLoops' Urban Circularity Assessment method. Supported application across five pilots, built Sankey and CARTO outputs, and managed two analysts.

Freelance Spatial Data Analyst

Ecotopia Urbana · Canary Islands and Catalonia

Delivered municipal energy and emissions analysis, and spatial evidence for the Urban Agenda for the Canary Islands, alongside later research roles.

Spatial Data Scientist (Intern), then Junior Researcher

Metabolic · Horizon 2020 CENTRINNO, Amsterdam and London

Intern from March to September 2021, then Junior Researcher from October 2021 to February 2022. Co-authored CENTRINNO's Cartography Alpha Version for nine European pilots; modelled EU27 building stocks and flows across 144 typologies for European Commission JRC study JRC130992; and trained a Sentinel-1/LUCAS land-use classifier in Google Earth Engine for an EEA-commissioned project.

Spatial Data Analyst (Intern)

BCNecologia, Barcelona's urban ecology agency

Developed and mapped a territorial proposal for Barcelona's home-care service within the Superilles Socials programme, combining neighbourhood structure, service demand and urban-context indicators.

Shaping Cool Cities

Researcher and developer

A Python data-fusion pipeline and six-city voxel models supporting 40,344 analysis cells; model validation is being rebuilt.
