What I'm looking for

I'm looking to lead and build automation, cloud platform, CI/CD, and AI-enabled engineering workflows that reduce operational effort, improve delivery speed, and help distributed teams work more effectively.

At CAS, I build automated deployment and content-release pipelines using Ansible, Terraform, Jenkins, TypeScript, Python, and FastAPI. My work reduced manual operator intervention by more than 75%, and I led delivery of a fully automated pipeline that reduced intervention by more than 90%.

I also use Claude Code to create agentic troubleshooting, feature-planning, and transcript-to-JIRA workflows; one troubleshooting framework reduced RCA time by 80%. I mentor teams on AI-assisted development practices, documentation, DevOps standards, and repeatable delivery workflows.

Across Territory Foods, Innovare Solutions, Evolve Bank, Rightpoint, and Acadian Asset Management, I've built CI/CD systems, Terraform infrastructure, AWS platforms, Kubernetes environments, and operational automation. I've supported distributed teams and large hybrid estates while improving deployment speed, availability, cost efficiency, and engineering ownership.
