Greenfield serverless e-commerce platform — millions of global customers

Designed and owned the "cocoa" microservices platform: 50+ AWS Lambda functions in TypeScript covering customer, product, auth, link-shortener, narvar-webhooks, doTERRA-dollars-wallet, catalog-loader, template-gateway, product-commerce, product-sync-interpreter, and content-search domains.
Used AWS CDK v2 (TypeScript) to define infrastructure as code ~ Cognito user pools, CloudWatch alarms, CodeArtifact, VPC, and Batch ~ eliminating manual console changes.
Implemented OIDC/OAuth 2.0 with Gigya (SAP Customer Data Cloud) and AWS Cognito; built a "bouncer" Lambda as the central API Gateway authorizer.
Applied CQRS and DDD (bounded contexts, aggregate roots) to separate read and write models across all bounded contexts.
Integrated Braintree Payments and Paymetric for global payment processing, Narvar for shipment tracking, and CrownPeak CMS; navigated multi-region payment compliance requirements.
Built a Java Spring Boot 2.x multi-module API (hybris-commerce-services-api) with JUnit 5, Mockito, JaCoCo, and SonarQube enforcement.
Established semantic-release + semantic-release-monorepo for automated versioning and changelogs across the Lambda monorepo.
