Sr. Software engineer @ From May 2015 to Present (8 months) Principal Software Engineer @ Currently working as part of the VPLEX Storage platform development team. Solely designed and implemented of the APIs for the establishment of secure VPN connections between the VPLEX management servers. Solely designed and implemented of the automation of the establishment of secure VPN connections using CLI commands. Led the team in the design and implementation of the very flexible automation framework (EZ-setup) for the configuration of the complex VPLEX system. This framework has reduced the configuration time from days to with in minutes for the end-user. and was designed to be scalable, flexible and easily extendable. Led the team in the design and implementation of resetting the complex VPLEX system to the manufacturing state. Official code reviewer for the python code base for the complete organization. Worked with remote team to design, integrate and code review LDAP and AD features into the EZ-setup framework. Led the team in the design and implementation of configuring a 3-way VPN to the cluster witness server. This effort involved coordination between various teams. Also this involved in a major refactoring effort of the existing infrastructure to support a n-way VPN and also making sure that the new functionality did not cause any regressions ,and also had improvements in user experience. This was done in record time satisfying all the defined quality parameters. Designed and developed a prototype for the QE test regression framework to test the EZ-setup. This framework takes advantage of the framework designed for the EZ-setup. Implemented part of the QE framework that resets the system to a manufacturing state every day and generates reports everyday. Introduced the Python unit testing framework to the complete organization. Took initiative to reduce the number of passphrases/passwords in the EZ-setup process by using the lockbox. Took the initiative to design a prototype for GUI based EZ-setup to use the existing cli based EZ-setup framework.

From June 2006 to December 2008 (2 years 7 months) Senior Software Engineer @ Description: Maintenance and enhancement of the EMC Virtual Lab Tool LRM. Lab Resource Manager (LRM) is a web based application that enables LRM users to book reservations for equipment and to request lab administration services for custom configurations or lab support. It manages equipment availability around the clock and allows sharing of resources in order to maximize utilization. LRM supports : Reserving Lab equipment ,Requesting hardware/software procurement,lab administrative services and configuration changes ,Browsing the inventory of available equipment . Role: Completely redesigned and re-implemented the complete back-end for the product which involves automatic collection of data from all the hosts on a daily basis . The re-design improved the accuracy of the data and the efficiency of the collection by reducing the turnaround time by 75% . Designed and implemented the novel concept of ini files which enabled parallel execution of scripts, improved the turn around time and de-centralized the scripts from hardware, also reduced the setting up of new servers to run the scripts from hours to with in minutes. Designed and implemented the dynamic host-switch-storage relationship which greatly enhances the lab staff duties .
