Engineering Showcase

A comprehensive catalog of the technical solutions, automation, and infrastructure I have architected throughout my career.

Cloud Architecture & DevOps

KUBERNETES • CI/CD • HYBRID CLOUD

  • Enterprise Kubernetes (RKE2): Architected production clusters utilizing Cloudflare tunnels, Istio Service Mesh, and Traefik ingress for secure application delivery.
  • CI/CD Pipeline Automation: Designed Azure DevOps pipelines using Helm charts and Ansible, standardizing deployments for 10+ projects.
  • Infrastructure as Code: Utilized Ansible playbooks to automate server provisioning and eliminate configuration drift.
  • High-Availability Virtualization: Engineered 3-node and 5-node Hyper-V clusters across multiple data centers to ensure business continuity.
  • Full-Stack Tooling: Developed "Netbox" (Django/Python) to serve as a programmable "Source of Truth" for asset management and IPAM.
  • Observability Stack: Deployed ELK Stack, Grafana, and Prometheus to visualize real-time application latency and system health.
  • Performance Caching: Optimized application layers by migrating from Valkey to Redis Cache Manager.

Automation & Scripting

PYTHON • POWERSHELL • ANSIBLE

  • Security Response (Log4j): Wrote and deployed a custom PowerShell script to detect vulnerabilities across all client endpoints immediately during zero-day events.
  • Identity Audits: Automated the detection of rogue service accounts and users missing MFA using PowerShell, significantly reducing attack surfaces.
  • Automated Reporting: Built Python (Pandas) pipelines to extract raw data from MariaDB/Zabbix, automating ISO 9000/9001 compliance reports.
  • Migration Automation: Scripted the migration of 30+ servers from CentOS to Ubuntu using Ansible, reducing manual effort by 40%.
  • Ticket Remediation: Developed Bash and PowerShell suites to auto-resolve routine support tickets (log rotation, patching), cutting response times by 30%.

Infrastructure & Networking

STORAGE • SECURITY • VIRTUALIZATION

  • Petabyte-Scale Storage: Managed 4PB of data on TrueNAS/ZFS systems, ensuring integrity for business intelligence teams.
  • SAN Engineering: Built dual Dell PowerVault ME5212 SANs from the ground up, configuring block-level replication for 40TB of critical data.
  • Global Networking: Configured secure VPN tunnels and Hub-and-Spoke networks using Meraki and Fortigate for 20+ international sites.
  • Secure Monitoring: Deployed Zabbix monitoring environments secured with PKI authentication across diverse client networks.
  • Legacy Modernization: Managed 5-node VMware clusters with redundant Rockstor (SUSE) storage backends.
  • Disaster Recovery: Implemented robust Veeam Backup strategies to ensure rapid recovery times for enterprise workloads.
