Case Studies
★ Featured
Migrating an AppSheet CRM to Express + PostgreSQL
Replaced a no-code AppSheet CRM hitting its limits with a typed Express + PostgreSQL backend and a React front-end — without losing a single record.
Result Cut manual data-sync from ~6 hrs/week to near-zero; eliminated the daily row-count reconciliation.
★ FeaturedBuilding a Multi-tenant CRM
A single Postgres-backed CRM serving multiple isolated tenants — schema-per-tenant isolation, shared application code, and zero cross-tenant data leaks.
Result 5 tenants on one codebase; isolation guaranteed by an automated property test on every PR; per-tenant export in one command.
