CRM / Customer Platform Stack (Next.js, PostgreSQL, Redis, Elasticsearch, Stripe) overview

A customer relationship management platform for tracking contacts, deals, interactions, and billing. Next.js provides server-rendered pages with fast navigation between customer records. PostgreSQL stores the relational CRM data model (contacts, companies, deals, activities, custom fields) while Elasticsearch enables instant search across all customer data. Redis caches frequently-accessed records and powers real-time activity feeds. Stripe handles subscription billing for the CRM product itself. TypeScript with Zod provides runtime validation for complex CRM forms and API payloads. The primary tradeoff is schema flexibility — CRM users expect custom fields and configurable workflows, which requires a dynamic schema layer on top of PostgreSQL.
