Sonora · architecture
Sonora architecture: a client app reaches the Sonora Gateway (Fastify, TypeScript, JSON-path field selection) through CloudFront and a Lambda authorizer. The gateway translates fields with AWS Translate and caches results and registries in DynamoDB.

Sonora Translation Gateway

Real-time JSON translation proxy

A multi-tenant proxy that intercepts backend API responses and translates selected fields on the fly via AWS Translate, cached in DynamoDB. Per-project registries hot-refresh every 20s (no redeploy), JSON-path field selection with array expansion, custom terminology to pin proper nouns, and a Lambda authorizer behind CloudFront.
