Context
Several related products were evolving separately, each repeating authentication, visual patterns, and infrastructure decisions.
Problem
Create one product ecosystem without forcing every application into the same release cycle or losing clear ownership boundaries.
Constraints
Shared identity and design, independently deployable applications, limited team resources, and consistent developer experience.
Architecture
A Turborepo monorepo shares typed packages, design tokens, authentication contracts, and build tooling while keeping application code isolated.
Decisions
Only stable cross-product concerns become shared packages. Product-specific logic stays local to avoid a central package becoming a hidden monolith.
Outcome
Six applications can present one coherent product identity while retaining independent development paths.
Learnings
A monorepo is valuable when ownership boundaries are explicit. Shared code without governance simply moves duplication into coupling.
