Work Experience
DevOps Engineer
Flexera
February 2021 - Present
- • Designed and built a Terraform module to automate the creation of IAM resources (roles, groups, users, policies) in both dev and prod accounts with appropriate permission boundaries for different roles. • Performed a Terraform version upgrade from 0.12.13 to the latest version 1.7, incrementally upgrading one major version at a time to keep the Terraform state in-sync with the configuration code. • Established cross-account access for other teams to our AWS accounts, specifically to our S3 buckets and SQS queues. • Automated the reload process of instances under an Auto Scaling Group in AWS using an AWS Lambda function with Python as the runtime. • Created a reusable module that creates development instances for developers using Terraform and configured the instances using CloudInit as userdata. • Upgraded Kubernetes versions deployed using Kops by employing a rolling upgrade strategy with zero downtime. • Collaborated with the AWS IT team to integrate our AWS accounts with LDAP, enabling easy access from OneLogin (an identity and access management provider). • With the DevOps team, migrated the Dev environment, which was sharing an AWS account with the Prod environment in its own VPC, to a new AWS account dedicated to the Dev environment. This involved creating all the necessary networking resources, IAM resources, and a Kubernetes cluster for microservice applications. • Implemented KMS encryption for S3 buckets to comply with company security standards. • Created custom Terraform modules for a Bastion Host integrated with AWS Systems Manager (SSM) to create and store initial SSH public keys, and a Bash script to automate the addition of users' public keys to the Bastion Host's authorized_keys file. • Proficient in configuring Deployments and Services in Kubernetes for container orchestration, running Docker containerized applications in Kops clusters. • Set up an Unhealthy Hosts alarm to trigger scaling of the Auto Scaling Group. • Implemented a Master-Slave setup to improve.

February 2019 - February 2021
- • Automated infrastructure provisioning using AWS CloudFormation and Ansible. • Participated in building and developing Docker containerized environments to break up the monolithic app into microservices, improving developer workflow, increasing scalability, and optimizing performance. • Analyzed system logs and identified potential issues with servers, storing related documentation of resolved issues and bugs on GitHub. • Managed GitHub repositories and permissions, including branching and tagging for different stages and applications. • Provided a consistent system upgrade environment using Kubernetes for deployment scaling and load balancing the application from development through production. • Created a CloudFormation stack that creates a Lambda Function to generate SSH key-pairs. • Developed both Python and Bash shell scripts and used Cron to schedule their execution times. • Was responsible for monitoring the Elasticsearch cluster and tuning ELK nodes when required. • Collaborated with development, QA, and other teams to ensure automated testing processes are integrated with the build system and to fix errors during deployment and building. • Customized applications according to business requirements. • Was responsible for addressing connectivity issues among various servers. • Used Python scripts to update content in the database and manipulate files.
