Principal DevOps Engineer - Platform (01/2022Present)
Verizon Portland, OR

  • 50% of the time responsible for infrastructure and platform engineering on AWS, supporting multiple production workloads with orchestration. Another 50% of time spent in contribution of improving DevSecOps culture and acceleration at Verizon NBI.

Senior DevOps Engineer (11/202001/2022)
Skyward, A Verizon CompanyPortland, OR

  • Leading initiatives to improve DevOps culture at Skyward by hosting weekly meeting "DevOps Round Table". Goal: Open hour for anyone to bring their topics of interest or concerns to the open agenda & be discussed. Helping identify bigger themes and problems that need to be solved and potentially turned into new projects for the DevOps team, such as - observability, monitoring, secrets management etc.

  • Continuous improvements in development and operations of cloud infrastructure powering Skyward apps, including managed AWS cloud services (SQS, SNS, SES, RDS, ElastiCache Redis, OpenSearch Service / formerly ELK) as well as unmanaged services (e.g. SonarCube, JFrog Artifactory, RabbitMQ ) and tooling (for example, maintaining in-house fork of kubesec for the purpose of enabling it to work with multiple other tools adopted by team such as vaulted & awsume ). Goal: Simplify delivery of infrastructure platform & tools that will enable and multiply developers cloud-native experience.

  • Lead on the effort of migrating Skyward codebase from BitBucket VCS to GitHub VCS through automation and streamlined management of GitHub resources through IaC. Goal: Enable better developers experience with use of GitHub, improve security by secure management of GitHub service users (with power privileges) and their various API Tokens, Personal Tokens, SSH keys etc. used by CI/CD bots.

  • Lead on the effort on integrating CircleCI with GitHub with security posture being Day-1 consideration. Individual contributions include secure management of CircleCI Contexts through IaC (which are gatekeepers of CI/CD system's access to other systems - such as AWS), development and deployment of CircleCI Orbs with result being streamlined CI/CD pipelines for all backend services. Goal: Leverage migration to GitHub+CircleCI as an opportunity to improve security model of CI/CD and reduce risks of exposing sensitive information granting access to other systems.

  • Lead on the effort on modernization and migration of Kubernetes platform ( all Kubernetes environments / multiple clusters) powering Skyward apps. Result is the migration of all workloads from AWS EKS 1.16 to AWS EKS 1.21 with minimal downtime (<1h). Goal: Prevent the auto-update of unsupported version of EKS by AWS, roll out new cluster with all benefits of new control plane and utilization of node groups based on spot EC2 instances. Additionally benefiting from improved logging, NewRelic monitoring, use of Cluster Autoscaler with node-group bidding priorities on scale-out, etc.

  • Lead on the effort on improving security posture of microservices powering Skyward apps by introducing Kubernetes Service Accounts to be used by Skyward services and removing the need for AWS IAM principals-based authentication of Skyward services with AWS services. Goal: Remove the need for managing AWS IAM Users and AWS IAM Roles for the purpose of Skyward services authentication to AWS APIs. Reduced the total amount of sensitive secrets being managed in K8S workloads and improved overall security posture of the whole system.

  • Designed solution for event-driven messaging of microservices powering Skyward apps (web & mobile). Lead the implementation of all the infrastructure (based on the proposed architecture) using IaC with Terraform in AWS. Goal: Further decoupling of microservices with intent of making microservice architecture better. One of the side-effects is simplified security model of cross-services communication, as they now rely on events and authentication with AWS services used for messaging.

Senior Software Engineer (in DevOps) (06/2018 – 11/2020)

  • Proposed and implemented observability strategies for product core infrastructure, most notably 30 self-managed MongoDB replicated clusters. To the full extent, utilized instrumentation with DataDog Agent, CloudWatch Agent and used DataDog Monitors for integration with PagerDuty (Global Routing and Services). Outcome: Enabled team to obtain 24/7/365 observability of all MongoDB infrastructure and take control of very fragile infrastructure which was causing lots of downtime. Lowered MTTR and boosted DevOps maturity growth for the whole team

  • Designed and implemented Slack apps/chatbots (as applications in AWS) for elevation of user privileges in all used database systems (MongoDB, AWS RDS, Aurora, AWS Redshift, DynamoDB). Outcome: Considerable savings in DevOps engineering hours spent on credentials management and IAM

  • Designed, implemented and deployed solution for executing automated on-line (0-downtime) migrations of self-managed MongoDB clusters in multi-account AWS environments. Outcome: Enabled team to better stick to 12-factor app principles and better governance and compliance with standards for managing PII data

  • Designed and automated solution for self service (AWS Service Catalog) deployment of MongoDB replicated clusters in AWS. Outcome: Enabled developers through automation to provision new MongoDB clusters with self-service style, yielding considerable savings in DevOps engineering hours spent on provisioning DB infrastructure
