great work, responsive in fixing issues

Helped setting up Apache Spark Cluster; He is very knowledgeable and went out his way working odd hours to get the job done.

Big thanks to him and reuse him for other projects

The work of Sourav and his big-data knowledge are very impressive, hence, I continue to use his great services. I warmly recommend hiring him in any work related to Big data: Hadoop, Flume, Cassandra, Kafka, Java etc.

Sourav has tremendous knowledge in the big data world. Wealth of experience in that space. He also has "soft skills" - ability to work with a lot of patience and explain the concepts in a way that can be understood by any one. He can act as an SME for any big data project. From architecture to implementation . I warmly recommend his services.
