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
