• Conceptualized, brainstormed and proposed a cloud tiering capability for unstructured data that is stored in OES (a file server) – Cloud Integrated Storage (CIS)• Implemented microservices in Go; Applied concurrency patterns • Added ZooKeeper based configuration store and Kafka based stream processor• Secured all the network communication using TLS• Integrated the CIS Microservices with SystemD and added High Availability clustering• Enhanced a Data Scale pattern and added envoy based Load balancing• Presented CIS to multiple stakeholders• Troubleshoot data download scale issues and proposed solution• Proposed and enhanced migration path to achieve near-zero downtime• Proposed and implemented file caching layer using global deduplication• Enhanced CIS to do an in-place upgrade from standalone service to cluster service• Developed a Linux kernel module to integrate CIS with the NSS file system• Guided others to build a solution on macOS to prevent unintended file download from the cloud.• Resolved multiple customer issues in OES file system component, NSS

• Enhanced user quota facility for extended attributes and data stream in the NSS file system• Developed purge utility to reclaim space from the salvage system in NSS based on configuration• Fixed complex performance issues• Handled NCS (Novell clustering solutions) component, a critical component of Open Enterprise server• Handled BCC (Business continuity cluster - Cluster of cluster) component responsible for high availability during distress events• Added BCC (Business continuity cluster – a cluster of clusters) support to latest OES releases to achieve high-availability which directly reflected in the company’s revenue

• Owned Storage management service (Back and restore solution for enterprise servers)• Developing and Maintaining the NSS file system for Open Enterprise Server• Troubleshooting and resolving multiple customer issues in OES file system component• Enhanced the atomic event file list to track all file system changes atomically which aided to improve the performance of various applications such as migration, backup, file system scanning for analytics etc.

• Developed a feature to migrate data from one server to other servers• Maintained storage management software (Back and restore solution)• Did various enhancements and fixed complex memory bugs in migration and SMS components

HP NonStop OS is a message-based operating system designed for software fault tolerance. It works with process pairs and ensures that backup processes in different CPUs take over in case of a process or CPU failure. Data integrity is maintained during those takeovers; no transactions or data are lost or corrupted. • Primary owner for Maintenance processor - which acts as an interface between various CPUs and IOs in HP Non-Stop kernel server• Enhanced Yprofile - a server-wide profiling tool to measure and optimize the performance Non Stop server processes• Primary owner for SWAN controller - An embedded box that provides the capabilities to integrate legacy protocol (X25, ATM etc.) with HP NSK server.• Research owner to study the feasibility to migrate from SNMPv1 to SNMPv2• Troubleshot and fixed complex heap corruption issues• Responsible for Knowledge management activities of the team
