DevOps Engineer
DWP Digital.
DevOps consultant with experience in utilizing agile delivery methodology to deliver mission critical projects on AWS cloud.
• Infrastructure as Code: Built new cloud hosted environment using Terraform and Terragrunt to migrate universal credit projects in to an immutable infrastructure. This includes built of DEV, QA, STAGING and PROD environments using shared modules.
• Infrastructure as Service: Worked with lead solution architect to define and built Manchester shared service environment for all CI/ CD toolsets. This includes built of GitLab (Source code repository), Jenkins (Automation server), Nexus (Repository Manager), SonarQube (Code Quality) with LDAP and slack integration.
• CI/CD Pipeline: Recently worked with a universal credit (ProveYouCanApply) project team to define their CI/CD pipeline using Jenkins. Work flow includes building tarball using Jenkins, push the tarball to Nexus, Pull the tarball and bake an AMI with Packer using Ansible as config management tool. Deploy the same using terraform.
• Security: Whilst building infrastructure code, followed all industry best practice by implementing encryption at transit and in rest. Secure management has been handled by parameter store within AWS and vault.
Recently implemented VPC endpoint services for various AWS services (both interface and gateway VPCe)
to ensure private connectivity between app and the services.
• Serverless Computing: Written janitor lambda function to make a scheduled start and stop of all ec2 instances in order to save costs based on its state. This will also check do a health check of the front URL to send HTTP post to slack channel as part of slack integration with lambda.
• ECS: Currently working on a project to move their ec2 environment in to Microservices running on AWS ECS cluster. This includes building multiple environments using shared terraform modules, writing root modules specific for the project in terraform and terragrunt.
• Monitoring: Data from all app containers are pushed to CloudWatch using CloudWatch agents in ECS instances,
Then streamed in to AWS Elastic search and filtered using subscription filters. Access to Kibana has been granted to Dev team in order to check the near real time for any application issue.
• Agile working practices (Scrums, Sprint Planning and Use of JIRA for tasks management)
• Implemented AWS session manager across UC platform for server accessibility for a secure and auditable instance management without the need to manage SSH keys.

• Collaborate with team to support the development process by deploying DevOps tools and methodologies such as Bamboo, Git/Bitbucket and cucumber. Designed and deployed dev/quality/staging/prod environments (AWS) to support the CI/CD model;
• High Availability/Data Security: Implemented Aurora replica for high availability and to improve read-IO performance for the application. Worked with KMS keys to ensure the data is encrypted at rest. Designed self-healing and resilient infrastructure to ensure application availability with the help of ASC.
• Infrastructure as a Code: Working on a terraform code to migrate the entire AWS infrastructure in to an immutable code. Using ansible as part of this workflow for configuration management.
• Disaster Recovery: Configured weekly/monthly backup of RDS database using lambda to ensure the copy of production data will be available in DR AWS account for disaster recovery purpose.
• Standardization: Standardized DB/Cluster parameter group based on AWS best recommendations. Participate in architecture planning sessions with development team to ensure the best practices are applied in every level.
• Written multiple python lambda function to make rest-api-calls to the application to order to help user-based experience.
• Recently set up a SFTP environment with S3 as its backend for client data upload. This design will have a notification triggered via SNS to invoke a lambda to call a HTTP endpoint to import the data and load in to the application.
