I build resilient, automated, and observable foundations that allow distributed systems to scale reliably under enterprise and high-throughput production load.
With a software engineering background and a deep, systems-first approach to Linux internals and networking, I bridge the gap between application code and complex infrastructure. I focus on building idempotent Infrastructure as Code (IaC), test-driven automation, and internal developer platforms (IDP) that eliminate operational friction and configuration drift.
What I bring to the table:
• High-Throughput Cloud & SRE:
Administered scalable AWS environments (EC2, ECS Fargate, Lambda, Aurora RDS, OpenSearch, SSM), executed live data layer upgrades, and served as primary responder in 24/7 on-call (ROTA) incident triage across a 50+ multi-cloud server fleet.
• Enterprise Platform Delivery:
Delivered mission-critical CI/CD and automation for large-scale enterprise and public sector distributed systems. Spearheaded Puppet 7 migrations (modular Hiera roles/profiles), authored 250+ Jenkins Groovy pipelines, automated multi-node Oracle WebLogic clusters (Packer, Vagrant, Python/WLST), containerized IAM (Keycloak), and implemented Kafka/Avro streaming.
• Test-Driven IaC & Custom Tooling:
Codified cloud topologies via Terraform, built modular Ansible roles tested with Molecule, and engineered internal tooling/microservices in Go, Python, and PHP for deployment tracking and fleet patch telemetry.
• Applied Systems R&D & Homelab:
Architecting hybrid lab infrastructure: bare-metal KVM/libvirt automation with Ansible & cloud-init, lightweight Kubernetes (k3s/ArgoCD GitOps), WireGuard mesh routing, and Model Context Protocol (MCP) integrations with Zabbix for AI-assisted incident triage.
