Zeptta · Seattle, WA

• Implemented AWS Resilience Hub across 50+ production services in four product verticals as the sole engineer, personally writing all Terraform for the deployment. Defined services, user journeys, and resilience policies from infrastructure tagging and EKS namespace structure.
• Mapped service boundaries in live production infrastructure alongside service owners and domain leads across three countries, reading source and deployed AWS resources to determine what was core to each service during ongoing migration and refactoring.
• Trained the client's staff resilience and security analyst, new to both Resilience Hub and Terraform, so the deployment could be owned and extended in-house after the engagement.
• One of the first enterprise-scale implementations of the rebuilt service. Reported bugs blocking infrastructure-as-code deployment and cross-account administration, which the AWS service team fixed during the engagement.
• Expanding the deployment into additional domains and building out AWS Fault Injection Service integration, running game days against the same service definitions with experiments codified in Terraform.

• Built the first version of an open-source MCP server connecting AI coding agents to Perforce P4 servers, now community-maintained with roughly 2,200 monthly downloads. Drove cloud strategy alignment with Perforce's C-suite.
