# Customer experience services

> Identity, catalog, discovery, CMS, sessions, reviews, and consultations.

## Identity and sessions

**Hodor** provides OTP authentication, JWT issue/refresh/revocation, and user profiles. Its FastAPI routes are in `hodor/app/api/v1/`; user and OTP persistence are implemented in `hodor/app/repository/`. It uses PostgreSQL for durable data and Redis for OTP cache/state, and integrates Vialogue, AWS Secrets, Medusa, and Shopify webhooks.

**Sesh** independently tracks visitor/session state in Redis. Its API endpoints are in `sesh/app/api/v1/endpoints/`. Session identity and authenticated user identity are separate concerns.

## Catalog, discovery, and content

**Atlas** exposes products, menus, collections, brands, and restock registrations from `atlas/app/api/v1/endpoints/`. It calls Medusa and uses PostgreSQL, Redis, SNS/SQS, S3, and AWS Secrets.

**Compass** owns search/recommendation behavior through routes in `compass/app/api/v1/` and `v2/`. Its client layer covers Atlas, Medusa, Redis, and Netcore/Unbxd.

**Tetris** serves cached CMS pages and recommendation widgets. Its service layer (`tetris/app/services/`) combines Strapi content with Compass gRPC-backed recommendations.

## Reviews and consultation

**Reflekt** owns reviews, ratings, questions, moderation, tags, and media. It is a FastAPI service with PostgreSQL/Redis and Medusa integration.

**Dermadesk** owns consultation booking, availability/slots, consult cart/order/payment operations, and prescriptions. It uses PostgreSQL/Redis and connects to Mint and Konsilo through gRPC, alongside Medusa, SNS, PostHog, S3, and JuSPay.

**Konsilo** is the clinical NestJS backend. `konsilo-be/src/main.ts` starts HTTP and gRPC endpoints. It owns doctors, availability, consultations, prescriptions, patients, and video, with PostgreSQL, SQS, S3, 100ms, and service integrations.
