Last Project: Was Involved in the migration of datacenter networking software (Cisco AAC) to vendor Infrastructure as Code (IAC) platform using terraform, Github actions and Jenkins, on AWS and GCP, primarily EKS and GKE clusters and other cloud services. Day to day tasks involved development and maintenance of cutomizied application workload into kubernetes clusters using helm charts and terraform and development of end to automation using CI/CD pipelines.

Previous project was to support rollout of FluentBit to an estate of approximately 120K endpoints adhering to strict IAC principles using Terraform and Jenkins CICD pipelines. Supported the migration of legacy observability platform to the fluent bit/ Fluent D/ Elastic solution.

Main responsibilities included the following.

• Development and maintenance of terraform modules for deployment of datacenter network software (Working closely with Cisco)
• Management of GCP and AWS resources (GCP and AWS compute, GKE and EKS clusters, S3 storage, AWS RDS)
• Design and development of CI/CD pipelines (Github Actions and Jenkins DSL pipelines)
• Development and maintenance of Helm charts for deployment through CICD (Mix of stock charts and Terraform Helm provider)
• Splunk queries to monitor infrastructure.
• Setting up and maintaining internal artifact repository (Google Aritifact Registry) to offload dependency on Banks shared Nexus service.
• Setup of Prometheus and grafana for observabilty (Consuming data from fluentbit)
• Automation scripting using Shell, powershell and pyton scripts..
• Introducing and promoting devops culture in the team.
