MariaDB Foundation Sea Lion Champions Nominees: Sumit Srivastava

Interview with Sumit Srivastava, nominated in the Adoption & Industry Impact category.

I had the pleasure of speaking with Sumit Srivastava, SVP Business Development & Products at Tayana, a Bangalore-based telecom software company. Sumit was nominated for championing MariaDB adoption in the telecommunications industry and its demonstration of open-source database delivering performance, scalability, and business impact in mission-critical systems. Like me, Sumit sits between technical and business — “the business people think I’m technical, and the technical people think I’m business,” as he put it. It made a lively conversation.
