Organizations
I am a curious person who studied Physics (BSc) and Applied Maths (MSc). Through the years, I developed a passion for handling large datasets and using compression to enable their analysis using regular hardware that is accessible to everyone.
I am the CEO ofironArray SLU and also leading theBlosc Development Team, and currently interested in determining, ahead of time, whichcombinations of codecs and filters can provide a personalized compression experience. This way, users can choose whether they prefer a higher compression ratio, faster compression speed, or a balance between both. I am also very busy in providing a way for sharing Blosc2 datasets in the network in an easy and effective way viaCaterva2 andCat2Cloud, a software as a service that ironArray is proudly providing.
As an Open Source believer, I started thePyTables project more than 20 years ago. Currently, and after 25 years in this business, I started several other useful open source projects like Blosc, Caterva2 andBtune; those efforts won me two prizes that mean a lot to me:
You can know more on what I am working on by reading mylatest blogs.
Blosc Development Team: May 2014 - Today
BDFL. Working on designing and coding libraries for efficiently compressing large datasets. Our main projects are:
In particular, C-Blosc2 and Python-Blosc2 implement very powerful yet flexible multidimensional containers for large datasets (NDim and NDArray).
ironArray SL: October 2021 - Today
CEO. Developing libraries for overcoming the limits imposed by technology when computing with multidimensional arrays, specially where the memory bandwidth becomes a bottleneck. Expert in compression applied to storage and computation.
Our main projects are:
Our main goal is to facilitate the use of Blosc technologies, making sure that data compression is fast and efficient in both in local machines or in the network.
