:-) Sorry Javier, and thanks for the ping Patrick.
Javier, I’ve invited you to the cogeotiff slack channel, which might just be easier to contact people working on COG and dynamic tiling. https://developmentseed.org/titiler/dynamic_tiling/ <https://developmentseed.org/titiler/dynamic_tiling/> might also be of interest for you.
