Professional Summary

Senior Site Reliability Engineer with 13+ years of experience in infrastructure engineering and automation. I deliver infrastructure as code via Terraform and maintain resilient Kubernetes environments for high-traffic production workloads. Highly proficient in Python and Golang, I develop agentic AI workflows, custom CLI tools, and CI/CD pipelines to reduce operational overhead. I leverage observability to identify single points of failure, refine alerting rules, and fortify system stability.

• CI/CD: Writes and maintains various Groovy pipelines to ship various applications to AWS and EKS.
• Network Engineering: Developed an internal NAT solution using AWS Transit Gateway to enable connectivity between overlapping CIDR blocks across business units and VPCs.
• Reliability Engineering: Improved AWS EKS cluster performance by writing Lambda lifecycle hooks (Python). Resulted in a 100x reduction in 500 errors during EKS Node scaling events.
• Secrets Management: Developed vaultcli (Python) to automate the migration of secrets from git repositories to AWS SSM Parameter Store (SecureString).

Senior DevOps Engineer | Nomis Solutions 2017 – 2021

• Microservices: Built NamesAPI (Golang) to standardize DNS records, tagging, and Terraform resource naming.
• Scaling: Wrote services-scaler (Python) to dynamically scale EC2 java worker nodes based on RabbitMQ queue depth.
• Monitoring: Overhauled legacy Nagios monitoring into a modern Datadog stack.
• Automation: Developed NomisPy - a composable, org-specific Python library for consistency and automation.

Senior Infrastructure Engineer | Forever, Inc 2015 – 2017

• Monitoring: Developed datamon (Python) to ship high resolution Postgres metrics for observability.
• Observability: Wrote qwatch (Golang) to ship high-resolution AWS SQS metrics to Librato.
• CI/CD: Built a cross-platform “Provisioner” (Golang) tool to automate package installation and config management runs on Linux and WIndows.

DevOps Engineer | BrandingBrand 2013 – 2015

• Orchestration: Architected fault-tolerant Mesos/Marathon/Zookeeper infrastructure.
• Load Balancing: Wrote MISHAP (Golang) to dynamically update HAProxy routing from Redis data, achieving 1s resolution for moving containers.
• DevEx: Created stage-me CLI tool, allowing developers to spin up full application environments with a single command.

Site Reliability Engineer | Livestream 2012 - 2013

• Monitoring: Wrote (and rewrote) scripts that pushed actionable alerts to Nagios monitoring.
• Infrastructure Automation: Wrote puppet manifests to manage infrastructure. Shipped collectd and statsd daemons to the hybrid EC2 / datacenter infrastructure.
• Observability: Built detailed Graphite dashboards to trace hard to debug issues at scale.
