Migration to Drizzle ORM & PostgreSQL
Infrastructure
Backend
Replaced raw SQL queries with type-safe Drizzle ORM schemas (packages/db) and automated migrations.
PLANNING
- ORM migration rationale. Selected Drizzle ORM for its zero-overhead SQL-like syntax and strict TypeScript schema inference.
BACKEND
- Drizzle migration. Migrated all database models to type-safe Drizzle ORM schemas in packages/db.
- PostgreSQL integration. Automated schema migrations and compile-time type safety across database queries.
DEVOPS
- Migration scripts. Added drizzle-kit migration pipelines and automated schema verification in CI.
