About Montera34

Imagotipo de Montera34

In Montera34 we analyze and visualize data to try to understand urban, social and cultural transformations; we develop software and we build digital infrastructures to enhance collaboration; we create production and meeting spaces, both temporary and permanent, to share technological learning, needs, doubts, data and analysis. We try to do all this using free data and tools, and we like to talk about why this is not always possible.

Montera34 is composed by Pablo Rey Mazón and Alfonso Sánchez Uzábal. It is a collective of two (Alfonso and Pablo) from which they carry out their web development, data visualization and digital art projects. We frequently work with our network of collaborators.

They both like rowing boats and sailing boats, and from time to time they take to the Bilbao estuary or the ocean coast.

You can usually find Pablo at Wikitoki in Bilbao and Alfonso in the French Pyrenees.

Pablo Rey MazónPablo (numeroteca.org, @numeroteca). He works and collaborates in several research and experimentation collectives such as Basurama, Wikitoki or Publiclab. His main concern is how to structure and make information more accessible. To do so, he develops research processes and data visualizations where researchers, clients or users can deepen and understand complex data.

He is currently developing the web community of the international network of informal waste recyclers (GlobalRec) and different visualizations on corruption and media in Spain with the color of corruption. He also develops PageOneX, a tool to visualize news coverage on newspaper front pages. In 2016 he launched with other wikitokers the community on data culture Bilbao Data Lab. He studied architecture and was a visiting scientist at the now defunct MIT Medialab’s Center for Civic Media.

Alfonso Sánchez UzábalAlfonso (voragine.net, @skotperez). He designs and implements digital infrastructure for various organizations, and develops websites.

Together with a small team, he launched Lab Place, an associative space for collective experimentation, digital fabrication and critical learning around technology in rural areas. He left the project in 2024. He has studied architecture at the School of Madrid and when he is AFK he and his family are transforming an old traditional barn into their home. He loves blogs, he reads many on a daily basis, and he also writes its own: Autonomía digital y tecnológica.
