Objective is to Maintain and Enhance client’s NEXUS Switch platforms with major focus on Platforms (ASIC, Hardware, OS, Kernel, peripherals, drivers, Firmware).

· Worked on different NEXUS switch across multiple platforms (N5/6K, N7K, N9K).

· Handled Multiple platform components namely USB, SFP, PSU, SUP, FAN, TTL etc. and device drivers for these platform components.

· Worked in HW integration and bring up on nexus platform.

· Worked on Multiple Broadcom ASIC Drivers on Nexus platforms (Carmel, Bigsure, Tahoe ).

· Have Upgraded kernel for multiple Linux based platforms.

· Worked on kernel panics and process cores.

· Worked on tools and protocols like Ethanalyzer, rpcapd, SNMP, PPM etc.

· Have worked on CISCO DME auto configuration for gold Diagnostics.

· Handle Escalations/CAP cases for CISCO clients for nexus platforms.

· Developed different features and Enhancements mainly on platform and OS(kernel).

· Debugged and fixed multiple vulnerabilities on different tools used on nexus switch and Linux OS.

Main objective for Mindtree was to make the platform Bluetooth enabled so that device can be accessed remotely.

· Ported Bluetooth Stack to Client’s Operating system and enabled Four Bluetooth level profiles

· Created a Bluetooth-USB interface to enable and manage USB driver and Bluetooth stack communications

· Worked with client engineers to integrate client’s Network stack with Bluetooth’s Internet Protocol Based profile (PAN)

· Introduced new Bluetooth Low energy Service specific to client’s requirement

· Created Bluetooth application on client’s Platform to control and manage Bluetooth on device

· Enabled Bluetooth on some of the catalyst Legacy Platforms

· Developed interfaces and new API’s to use Bluetooth connect as a transport for proving wireless Network and enabling remote access over IP So that all of the operations that can be done using Internet/Intranet such as SSH, SCP, Telnet etc over IP can be utilized

· This way no third party App or tool is needed to communicate, Configure, Upgrade on the remote device Everything can be done via Terminal/Browser access on windows, MAC and all other OS enabled witH Bluetooth PAN

· Implementation of Bluetooth Hands free Profile with Training (Training Project, Developed Bluetooth Hands-free Profile with six member team on BlueZ Bluetooth stack

· Implementation can connect to an android phone and was capable to Pickup, Hold, Disconnect a calls as per the

· Bluetooth specifications.
