About the Author

Amit Nandi studied physics on the loose college of Brussels in Belgium, the place he did his learn on computing device generated holograms. laptop generated holograms are the major parts of an optical desktop, that is powered by means of photons operating on the velocity of sunshine. He then labored with the college Cray supercomputer, sending batch jobs of courses written in Fortran. This gave him a style for computing, which stored transforming into. He has labored greatly on huge enterprise reengineering projects, utilizing SAP because the major enabler. He centred for the final 15 years on start-ups within the facts area, pioneering new parts of the knowledge know-how panorama. he's at present concentrating on large-scale data-intensive functions as an firm architect, facts engineer, and software program developer. He knows and speaks seven human languages. even though Python is his desktop language of selection, he goals in order to write fluently in seven computing device languages too.
