Jul 2016 – Jul 2018 · 2 yrs · Pune Area, India

• Worked on various large scale enterprise software projects as a Linux Software Engineer in the Cloud division.
• 1. Cross-product integration between NetBackup and CloudPoint | September 2017 - July 2018
• As part of an 8-member agile team, worked on the design and implementation of a framework to protect data on hardware storage arrays and in the Cloud (AWS, Azure, GCP), through the integration of two enterprise products.
• Wrote code in C++ to parse protocol requests, add a new backup type, quiesce the storage stack and enable secure communication between the two products.
• Gained practical experience with snapshot based techniques for protection of data.
• 2. Securing cross domain master-master communication for TAIR | February 2017 – September 2017
• Targeted Auto Image Replication is a NetBackup feature which allows a consumer to setup automated backup image replications to specific master (controller) servers across domains.
• As part of a 12-member agile team, designed, implemented and tested a secure mechanism for this use case. Led the design effort for the clustered master use case, bringing all stakeholders to a common consensus.
• Wrote code in C and Perl for the generation, deployment, exchange and validation of X.509 based certificates.
• 3. Cross-product integration between NetBackup and HyperScale | August 2016 – January 2017
