To whom it may concern,

Prachi Sharma has been invited as trainee for her bachelor's degree in IRCCyN

laboratory from January 2014 to March 2014 under my supervision.

During her stay here she worked on the use of erasure coding for distributed

storage and Cloud computing. The context of her work were both theoretical,

with the understanding of algorithms and methods related to FEC codes, espe­

cially using a discrete tomography-based method called the Mojette Transform

and its behavior as an erasure code, and practical consisting of handling FEC

codes and distributed storage systems, contributing to RozoFS project in collab­

oration with the start-up Fizians, and developing a web interface that interactswith the distributed file system.

In less than two months, Prachi acquired a great experience and confidence on

the subject. She is eager to share and learn and showed autonomy.

Best Regards,

Dimitri Pertin
