Confidential, Mooresvile, NC

Cloud Architect/Coach

Responsibilities:

• I was the Cloud Architect for Confidential ’s Confidential . Agile Transformation Office is a team chartered to lead, enable, guide and support Lowes in adoption of agile principle and best practices. DevOps, along with Lean Portfolio Management, Agile Execution were the practices areas, among others for Confidential .
• Created DevOps mind-set courses tailored to Executive, System Teams, Solution Teams and Quality Analysts.
• As for the System Team, I coached them in achieving CI/CD best practices for the Cloud migration. Confidential ’s digital system is progressively moving from their datacenter to the Cloud (GCP)
• The Search, Catalog, Cart services has been transformed into micro-services via Spring-boot applications. Those, in turn, have been made Docker Containers via fabric8 plugging
• Wrote Terraform scripts to that spin of Cluster using Kubernetes (k8s) or using Google Cloud Deployment Manager to automate the configuration of all the GCP resources.
• The Search service interacts with Fusion/Slr,. Fusion/Slr is not dockerized but runs in GCE so, I am configuring Cluster Networking (network, firewalls, routes,…) as well as creating Services, Controller, Ingress, Secrets, ConfigMap, Persistent Volumes within Kubernetes to orchestrate the deployment of the containerized applications.
• I did handle large scale Kubernetes deployments in GKE with auto-scaling capabilities. Prometheus is the monitoring tool via a Google StackDriver Collector.

Confidential Bridgewater, NJ

DevOps Architect

Responsibilities:

• I was responsible for providing the architecture and DevOps related tasks for the development of two prototype products called CCID and IVS and making sure that the CI/CD pipeline is up and running.
• I created and configured Docker containers and Kubernetes using Ansible scripts to run on EC2 virtual machines.
• As of the services written by Java developers, I converted them to be deployed in Docker containers and others in Cluster using Kubernetes (k8s) for the pre-staging and production environment. All are deployed in AWS with Linux types EC2 instances. For k8s clusters, I am using 2 controller nodes, one etdc node and pods in at least 3 containers
• I was configuring developers' environment to automatically deploying artifacts in target environments via Jenkins. That apps that are defined in docker-compose are deployed on a Swarm cluster
• A trusted Docker registry has been created in Nexus via NGINX to hold artifacts that can be promoted/pulled.
• I participated to an hour presentation of "Containers" focusing on Docker with an hands-on video
• I was other teams of Confidential 's IT organization on Docker Containers, Kubernetes(overview and basic setup in AWS environments for the )
• I was helping teams to set up AWS environment to have instances for deploying compute infrastructure such as VPC, subnets, network access control lists, security groups, and EC2. Those resources are used to create Docker container and Kubernetes via Ansible scripts.
• All the materials include lessons learned, advices, tips and DevOps best practices for doing things better: reducing re-work, increasing the productivity and optimizing the uses of existing resources.

Confidential, Jersey City, NJ

Amazon Web Services Architect

Responsibilities:

• I was part of an Agile Development team that helps Confidential 's clients to move their network infrastructure either totally in the public cloud or to adopt an Hybrid approach on AWS with emphasis on Security .
• I designed, built and deployed many applications utilizing almost the AWS Stack (EC2, VPC, R53, IAM, CloudFormation, CloudWatch, EBL, SNS, SES, SQS, Glacier, CloudTrail, Amazon Direct Connect ) with focus on high-availability, scalability and fault-tolerance.
• For Hybrid AWS technologies, I integrated AWS VPC with clients' on premise data centers and networks while using security best practices (Security Groups, Access Control List, MFA on accounts, custom policy, etc…) I used either Amazon Direct Connect or OpenVPN Access servers.
• Set up a consolidated billing on multiple AWS accounts, CloudWatch alarms when costs reach certain points.
• I did create many Chef recipes/cookbooks in Ruby to automate the installation, build and deployment of DB servers, elasticsearch engines, web servers, etc… in hundreds of EC2 instances.
• I also used CloudFormation templates to automate and deploy AWS resources in dev, test and production environments.
• In some instances, instead of using hosted Chef, I created stacks within AWS OpsWorks to run custom cookbooks, testing chef recipes/cookbooks with test-kitchen/chefspec/serverspec
• Since someone cannot provision VPC, EC2 or ELB directly through OpsWorks, I used Jenkins scripts to orchestrate the workflow so that the resources are automatically provisioned prior to provisioning the OpsWork stacks. That is one best practice for Continuous Integration and Continuous Delivery.
• Created versioning and life cycle policy on S3 buckets and archiving them on Glacier after a specific time.
• Applied Chef Server, S3 and auto-scaling for deploying EC2 instances with Chef
• Within VPCs, I defined security at the instances level (security Group) as well as the subnet level (NACL).
• Monitored metrics/events via CloudTrail with CloudWatch and creating alarms to be sent by email to admins account using SES(Simple Email Service)

• Even with our small team, since the beginning, I recommend using Nexus Repository manager to centralize all the binary artifacts as I anticipated the source code to grow. Enforcing code quality with SonarQube. Bamboo is hosted in the Cloud and SonarQube Scanner is configured from Bamboo.
