Message

At TradeStation, I administer 8+ production EKS clusters supporting critical trading systems and partner with product and development teams to define service-level objectives. I use Datadog, CloudWatch, and Logz.io to improve observability and support incident response.

I implemented Terraform infrastructure and automated deployment pipelines that reduced manual errors by 85%, and built n8n workflows that cut operational toil by 60%. I also evolve GitLab CI/CD practices used by more than 20 development teams.

As a freelance DevSecOps consultant, I design cloud solutions for companies in finance, healthcare, and e-commerce, delivering 99.9%+ uptime SLAs. Earlier, I worked in SRE, DevOps, and test automation, including building Cypress test suites that reached 85%+ code coverage.
