Shipping a large change to a production system with a big user base creates a very familiar kind of stress. The business wants to move fast, but engineers know that “big bang” deployments carry a disproportionate amount of risk. A single bad deploy can mean a major incident, a complex rollback under pressure, and a…

At a certain stage of growth, the codebase stops making intuitive sense. Logic that used to be simple becomes spread across multiple services. A change to the “user profile,” for example, starts affecting five different parts of the system, each with a different definition of what a “user” is. This happens when the original, shared…

A new feature request lands, and you realize it has to touch the old permissions module. The project planning meeting suddenly gets very quiet because everyone knows any change in that part of the legacy code means weeks of careful testing, unpredictable behavior, and a high-stakes deployment. This is the friction point where building new…

The repository structure that works for a two-person startup almost never works for a fifty-person engineering team. What starts as a simple, clean codebase eventually develops friction points as more people and services are added. The conversation about whether to use a single Monorepo or split work across multiple repositories usually starts here, when dependency…
