• Working as a Developer for debugging, developing and unit testing various modules of SSR (Physical Chassis Router) and EVR (Ericsson Virtual Router) of Ericsson. • Debugged and fixed many TRs (Trouble Reports). • Worked as part of the team on 'Ingress Optimization' feature on Ericsson Virtual Router, and resolved multiple complex issues here involving multi-threading, race conditions and mutex. • Worked on the development of a major feature called 'Packet trace and debuggability' which mainly focus on the improving the packet debug ability that will help in reducing packet loss Wrote a counter function and wrote code for the implementation of 6 CLIs for the feature. Also did unit testing whenever some bugs appears. • Worked on the development of a feature called ‘PARP Hardening’ to increase the robustness of PARP module in EVR by monitoring the causes of packet drops. The work involved implementation of IPC messages from RP(Routing plane) to LC(Line card) and vice versa to collect PAP states and compare them. Also implemented CLI commands for it. • Currently implementing a “logdump” command to collect all logs related to PARP module within a single file in the EVR.
