Building the Platform as a service to migrate LinkedIn workloads to the public cloud.

Environment: CentOS, Azure, Python, MySQL, GitHub and Agile methodologies.

• Designed and developed the secure audit logging support to help the infosec team monitor all the CRUD (Create, Read, Update and Delete) operations in the PAAS.

• Designed and developed the feature to enable VM boot diagnostics feature in the Platform to troubleshoot failed Azure Virtual Machine ScaleSets.

• Migrated the PAAS instances to use the new Azure Platform VM images with zero downtime.

• Designed and developed batch update and deletion of Azure Virtual Machine ScaleSets.

OpenContrail system – an extensible platform for Software Defined Networking (SDN)

Working on Contrail MicroService and cloud orchestration with docker.

Environment: CentOs, Docker, Ansible and GitHub

In the microservices architecture all processes are running in their own docker container. The containers are grouped together into services. The containers are deployed using ansible and docker-compose

• Designed and developed the feature to scale up and scale down the micro-service containers in a distributed environment.

• Designed and developed support for deploying OpenStack Pike containers.

• Designed and developed support for deploying Contrail containers using the contrail micro services architecture.

• Developed solution for getting the entire build environment containerized so that developers can compile and build the code in a container without having to login into their build servers or VM.

• Developed solution to deploy the entire Contrail cloud using Ansible and docker-compose in one touch to make it simple for the end user.

Environment: Ubuntu, Python and GitHub

Contrail Server Manager is an orchestration system that deploys the Contrail cluster. It provides functions to install base OS on servers (reimaging), and configuring the servers by installing necessary packages, configuring and starting different services needed to provide a contrail role functionality on these servers (provisioning)

1. Architect, design and implement the JUNOS Management and Control plane components (FBSD based) that fit seamlessly into the existing Media-flowcontroller (CentOs based) management paradigm.

2. Used the JUNOS SDK API’s to accomplish this task. Provided the DMI interface using the Virtual JUNOS as an infrastructure component. Used the Linux ‘qemu-kvm’ as the hypervisor. Modified the Virtual JUNOS (Junos on KVM) to make it sleeker to suit our requirements.

3.Architected the Pacfica project for managing the Media-flow Controller app in a x86 line card in the MX router.

4. Designed and implemented a single solution that works for both the Standalone MFC as well as for the MFC that runs in the x86 line card in an MX router

5. Designed and implemented the PXE booting of the x86 line card with the media-flow-controller image

6. Came up with a innovative way to use JUNOS features that are not exposed in the JUNOS SDK

7. Interact with various teams across Juniper to understand and gain knowledge on the other Juniper modules for this integration.

8. Mentor and guide the offshore team
