- Work with Apollo Router for federated GraphQL architectures and schema composition.
- Ensure robust error handling, observability, and performance optimization across services.
- Build and maintain data access layers using GORM (Go) and PrismaORM/TypeORM (TypeScript).
- Implement data integration workflows with relational databases (PostgreSQL) and data warehouses.
- Deploy and operate services on containerized and serverless platforms like ECS/Fargate and Lambda across major cloud providers (AWS/Google Cloud Platform/Azure).
- Use Infrastructure as Code (IaC) tools such as CDK or Terraform for environment provisioning and configuration.
- Implement observability practices with distributed tracing (X-Ray/OpenTelemetry), structured logging, and metrics.
