Work Experiance
I have 5 years of experience in development in networking domain. My most of the work was in user space. Below is the timeline of my work with organisations:

Freescale Semiconductor

Software Engineer

During the service, I was involved in Ethernet features implementation and bug fixes on Freescale SoCs. I worked on both kernel space and userspace space projects. Those projects are below:

  • Network Applications Development Kit (NADK - Freescale Proprietary Project)
  • Application Specific Fastpath (ASF - Freescale Proprietary kernel Space Project)
    • 2014 - 2016

    NXP Semiconductors

    Sr. Software Engineer

    During the service, I was involved in implement various Ethernet drivers and upstream some of them apart of many bug fixes. I worked on NXP HW, simulation and emulation environment. Below are the major projects in which I have contributed:

  • Data Plane Development Kit (DPDK)
  • Open Data Plane (ODP)
  • Vector Packet Processing (VPP)
    • 2016-2019
    Projects
    Below is the list of projects that I have worked on with summary of my activities:

    Data Plane Development Kit (DPDK)

    About

    DPDK is an Open Source Data Plane Development Kit that consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures.
