Project History
Shell Email Router App
Shell's enterprise transactional email platform with a multi-tenant REST API that routes outbound mail for internal applications through a Halon MTA, with a provisioning API, an operations portal, and a sandboxed template-rendering service.
I worked across the whole stack, helped consolidate the platform into a TypeScript monorepo, migrated it from AWS Lambda and API Gateway to containerized Fastify services on EKS (Docker, Helm, and LocalStack for local development), moved the data layer to Drizzle ORM with dbmate migrations and a CI schema-equivalence gate, and built portal features such as a connection-diagnostics search page in Next.js.
I also led the platform's test-quality program, auditing every module against a rubric, replacing hollow tests with behavior-pinning ones, adding mutation testing, and fixing the authorization, audit-trail, and compliance defects it surfaced, including fail-closed permission gates, cross-tenant read oracles, and RFC 8058 one-click unsubscribe and suppression handling.
