Platform and Infrastructure Engineering.

Lead the on-premises Kubernetes microservices infrastructure at PANW, with special focus on:

• Building, maintaining, scaling 40+ production/staging clusters. (bare-metal, on-prem, ansible, kubespray, weave-net, calico bgp)

Also building supporting infra for these k8s environments:

• GCP, CI/CD, GitOps/ Dev Productivity, Logging, Monitoring, Provisioning, Config Management

• Helping dev & infra team design large scale distributed applications with a focus on reliability, automation, operability and performance.

Our team built a multi-region AWS cloud infrastructure that powered Branch's business, and handled billions of transactions, events and TBs of data, per day.

My areas of focus were:

• Building, maintaining and scaling multiple production Kubernetes clusters on AWS. (kops)

• Multi-tenant multi-region AWS infrastructures, storage systems and content delivery networks.

• CI/CD Build & Release automation on AWS, containers, orchestration systems, EC2, serverless; build pipelines (Jenkins, CircleCI etc).

• Infrastructure automation for containers, security, networking, and cloud-based delivery models.

• Architecting, developing and maintaining production-grade systems systems such as Kafka, Kubernetes, Redis and Postgres.

• Operations automation (Salt/Puppet/Ansible/Terraform, Fabric, Linux, etc).

• High-volume deployments (JVM, Nginx/HAProxy, ELBs, CDN etc).

• Logging & monitoring (PagerDuty, Cloudwatch/CloudTrail, ELK, Prometheus/Grafana).

• Providing on-call support, ensuring the production system is healthy 24/7.

Technical lead for the cloud integrations & packaging team, responsible for integrating the core (SDN) networking plugin into Rackspace/OSA, Mirantis, RedHat OSP and Canonical OpenStack distributions. Used the following tools & platforms:

• Ansible, Puppet, Python, Bash for bare metal, virtualized and Google Cloud environments,

• Vagrant, VirtualBox, Libvirt, Linux Containers (LXC),

• Ubuntu, CentOS, deb/rpm, mirror scripting

• SDN, DevOps deployment automation, OpenStack neutron networking

My experience consisted mainly of:

• Architecting deployments for cloud and container/docker based frameworks

• Opensource contribution for openstack-ansible, fuel-plugin communities

• Development & maintenance for our opensource code (plumgrid-ansible playbooks, plumgrid fuel plugin)

• Developing an automated test infrastructure that ran our deployments with openstack modules, and solution testing pipelines that ran on jenkins CI for internal code commits

• Technical Documentation with Latex, Sphinx: Release Notes, User Guides, Architecture Guides, Training Material Internal + Outbound
