Gerardo Ezequiel Martin Carreno

I'm Gerardo, a full-stack spatial data scientist based in London. Curious by nature, I started at the intersection of GIS, urbanism, and sustainability, and my love for geospatial technology has never stopped evolving: from cartography to spatial data science, from geospatial data engineering to GeoAI and data visualisation. That curiosity took me from Barcelona's Superblocks project to EU research on urban circularity, from remote sensing with Sentinel-1 for the European Environment Agency to building location intelligence systems with Python, PostGIS, and deck.gl.

I'm always learning, always hunting for the best courses and resources to feed that curiosity. For a long time it was a solo journey: spending hours scouring the internet for the right material, eager to share what I found with colleagues and fellow practitioners but with nowhere to put it all. At the same time, I managed my career with scattered tools: Notion dashboards to track applications, boolean searches across LinkedIn and niche boards, an Excel spreadsheet to compare salaries. I spent hours every week on tasks that a spatial data scientist should be able to automate.

I built what I wished existed, for the community that shaped my career.

So I did. What started as a weekend project to automate my own job search grew into something bigger. I realised the problem wasn't just mine. Every geospatial professional I spoke to had the same frustrations: no salary transparency, no clear career paths, no tools designed for our specific industry. Geospatial Careers is the result: career intelligence that understands the difference between a GIS Analyst and a Spatial Data Scientist, built by someone who has been both. And all those courses, resources, and insights I spent years collecting finally have a place to land.

At its core, this is my attempt to take career decisions based on data, not just intuition. It is a living, evolving project, and it is shaped by the community that uses it. Every salary submission makes the benchmarks more accurate. Every piece of feedback influences what gets built next. If you work with spatial data, whether you are mapping cities, monitoring climate, building web maps, or managing GIS teams, this is for you.
