Summary

Experience
Linux Cloud Operations Administrator
Information Technology
Aug 2019 - present
  • Deliver solid foundations for Vector Solutions’ journey to one DevSecOps-run company:
  • Team-focus: Network across formerly several companies, incite team discussions to get best practices and standards agreed upon. Centralize and standardize AWS resources. Collaborate with development, explicit DevOps, cloud ops, and security teams to foster oneness.
  • Cloud Operations: Introduce Infrastructure as Code, source code control, provisioning automation, and enterprise collaboration to our Operations’ department. Design expert disaster recovery methodologies and techniques for all resources and processes. Set up remote state handling for Terraform Cloud and easy self-service deployments. Implement Chatops for transparency, collaboration ease, and lightning resolution speed, by integrating pipelines. Build and distribute base and purpose-built AMI’s into a heavily image-based system, for all new builds. Inaugurate desired-state configuration management with Chef. Provide hardened, baked-in security images and base containers. Furnish high-availability, load-balanced, auto-scaled, production infrastructure environments. Build servers. Update, patch, and standardize sFTP servers, exporters, web servers, jump boxes, application servers, and storage. Contribute automated patch management and policies. Solve backup issues, permanently, in on-premise, AWS, Rackspace, and enterprise backup and storage appliances (Drobo and Barracuda SAAS).
  • Security: Develop absolute least-privilege IAM and role-based access. Remediate Rackspace security issues. Bring the security conversation to the beginning of all work. Automate security baselines. Initiate the use of source control for security remediation scripts. Establish Compliance as Code processes to harden and test operating system-level security with Chef. Stop and investigate active security incidents in progress. Furnish several corrective measures; rootkit hunting, security in pipelines, ssh guarding, ip tables, upgrading to the latest Linux distributions, standardizing user and secrets management, OS-level firewalls, and code scanning(SAST tool, Whitesource) to address continuing security issues.
  • Developers: Pair with developers and deliver quality migrations: Migrate products from Rackspace to AWS. Implement the last physical to digital application transformation needed for all employees to work remotely; an internal product for converting content from M&A companies into our corporate-chosen course player. Transform applications to current architecture and security practices. Supply rollout support and ownership over deployed products. Also implement container management: Establish Docker pipelines and ecosystem; create Docker image registries, Kubernetes clusters, container scanning, and code-scanning. Slim down the monolith, update version 1 containers and train developers on current practices; use of purpose-built, minimal images, how to properly use FROM, and integrate all steps to chatops. Start container vulnerability scanning, and building containers with DockerFiles and multi-stage builds. Help support a PHP-based in-house application..
  • Networking: Launch the use of Terraform for network security automation, to normalize our network security paradigm across several companies and accounts. Build, secure, troubleshoot, and connect virtual networks. Develop, upgrade, migrate and roll out OpenVPN, a VPN solution. Standardize security groups, ssh tunneling, and key-based logins.
  • Databases:Build local MongoDB and AWS DocumentDB databases. Perform a mongo restoration. Migrate an Access database, and proffer agile-style user support to internal customers, for this new technology implementation, across Linux, Mac, and Windows.

Principal Infrastructure Engineer
Information Technology
Feb 2019 - Aug 2019
  • Contract for Luxottica. Architect and build in-store-server failover to Azure. Refactor the Puppet/Spacewalk/Ansible/UMS Igel standard build to Azure/Terraform/Kubernetes/CentOS/Docker. This choice has saved Luxottica significant money, over ordering physical servers to ship to edge, world-wide stores.
  • Hot ticket troubleshooting, troubleshoot Bash scripts. Deploy fixes through UMS, and Igel proprietary desired-state solution, not just on the store-level as is custom, but program version-agnostic fixes to deploy across builds. Build tools for Luxottica’s proprietary Personality Server, so level 2 support can execute needed commands in-stores. Replace several custom modules with easier-to-maintain modules. Train coworkers on UMS, Azure, Terraform, and Docker.
  • Transform Luxottica to DevOps; provide a dev environment via Docker images for team members, deploy and integrate team-communication platform (Slack with Git) change workflow to include peer-reviewed merge requests and non-prod environments, provide development transparency. Procure database connectivity to and develop SQL based reports on Remember for report to management about some of the state of our team.
  • Lead and coordinate technological change across our international IT teams. Recommend and implement solutions to a range of challenges. Build in security, redundancy, peer review, balancing, implement current best practices.
  • Took the initiative and cost to perform intense research, in SanFrancisco, on Docker environment security and best practices, through networking for advice at Dockercon, to design the best system for Luxottica. Attended Docker classes, met with several vendors, and received ongoing vendor training on security (Aqua, Stackrox), container scanning, container-based monitoring, Kubernetes security, Docker image registries, Hashicorp products, and management of space with Docker. Networked and joined communities for ongoing support and advice. Did not get a chance to learn Istio or service meshes, yet.
