Professional Services by Francesc Alted

I am an independent consultant and developer with more than 25 years of experience wrestling with Big Data in many different ways, as well as leveraging compression techniques for accelerating I/O. With customer needs in mind I can apply my experience to help determining the best options for handling and analyzing big datasets in the most efficient way.

I am the author of the fast Blosc compressor that has become the basis for some well known libraries like HDF5 and Zarr. Also, I have created projects like PyTables and Caterva for storing and handling extremely large amounts of data.

What I offer:

  • Development services on existing or new packages in the Blosc ecosystem (including PyTables and bcolz).

  • Development services for custom software that is for doing optimal I/O (either using Blosc/PyTables/bcolz or not).

  • Consulting services on better leveraging the Blosc ecosystem in your own setups. Services like implementing new functionality, providing efficient binaries or optimizing parameters for large streams of chunks are typical.

  • On-site training services about many aspects of Data Containers for Big Data and also Python. Look here for an example of my favourite topics. I also did quite a bit of tutorials for conferences, like the one for PyData Barcelona 2017 or Advanced Scientific Programming in Python in Reading, UK (2016).
