01
Interactive maps & geospatial dashboards
Web maps that answer real questions — supply-chain actors, monitoring networks, land cover and risk layers — served fast from PostGIS and GeoServer.
02
Management information systems
Full-stack data platforms: data model, APIs, admin and reporting interfaces, built end-to-end with the people who will use them.
03
Spatial analysis & remote sensing
Land-cover change, rapid carbon assessment, digitisation over satellite imagery and spatial modelling for programmes and reports.
04
Data pipelines & machine learning
ETL, data quality and analytical pipelines in Python, plus classification and regression models when the problem calls for them.
