• Container Migration: Lead migration of services from AWS Lambda to Amazon EKS; build and maintain Circle CI and Argo CD CI/CD pipelines for containerized deployments.
• Technical Leadership: Contribute to and review all engineering deliverables; define Definition of Done criteria per phase; champion code quality, test coverage, and security standards across the team.
• Documentation & Handoff: Produce deployment runbooks, pipeline documentation, architecture diagrams, and AWS Well-Architected alignment summaries.
