• Built and influenced the tools and utilities that are part of the developer tooling helping simplify day to day tasks

• Served as catalyst to deliver truly disruptive products that are growing rapidly within Verizon Robotics Business Technology portfolio

SKYWARD (A Verizon Company), Portland, OR
Senior DevOps Engineer, Remote (11/2020 - 01/2022)

Led foundational infrastructure development, maintenance. Initiated and facilitated improvements of DevOps culture by hosting a weekly meeting, the DevOps Round Table, championing an open-hour event for anyone to bring their topics of interest or concerns to the open agenda for discussion, covering themes such as observability, monitoring, secrets management, Kubernetes autoscaling.

• Led the effort of modernization and migration of the Kubernetes platform including production environments / multiple clusters, powering apps, and migrating all workloads from AWS EKS 1.16 to AWS EKS 1.21

  • Prevented the auto-update of an unsupported version of EKS by AWS, rolled out a modern cluster with all benefits of the new control plane, and utilized node groups based on spot EC2 instances.

  • Improved CNI, logging, cluster observability and monitoring, and introduced the use of Cluster Autoscaler with node-group bidding priorities.

• Contributed continuous improvements in the development and operations of cloud infrastructure powering the apps, delivering quality services and products that were on time, on-scope, within budget, and per customer and regulatory (FAA) specifications.

  • Managed AWS cloud services (SQS, SNS, SES, RDS, ElastiCache Redis, OpenSearch Service / formerly ELK), as well as unmanaged services including SonarCube, JFrog Artifactory, and RabbitMQ, and tooling including maintaining an in-house fork of kubesec, enabling it to operate with multiple other tools adopted by the team (such as vaulted and awsume), simplifying the delivery of infrastructure platform / tools that enabled and multiplied developers’ cloud-native experience.

• Piloted on the effort of migrating codebase from BitBucket to GitHub VCS through automation and streamlined management of GitHub resources through IaC using Terraform.

  • Enabled better developer experience with the use of GitHub.

  • Improved security by secure management of GitHub service users and their various API Tokens, Personal Tokens, and SSH keys used by CI / CD bots.

• Directed the effort on integrating CircleCI with GitHub with all important security posture considerations, ensuring proper mitigation of risk, alignment with corporate strategy.

  • Secured management of CircleCI Contexts through IaC using Terraform, the gatekeepers of the CI / CD system's access to other critical systems such as AWS.

  • Developed / deployed CircleCI Orbs with goal of streamlining CI / CD pipelines for all application code and infrastructure code, with orbs serving as go-to service catalog offering for service blueprints.

  • Leveraged migration to CircleCI / GitHub as an opportunity to improve the security model of CI / CD and reduce risks of exposing sensitive information and granting access to other systems
