[architecture] Building microservices from day one with a small team

Start with a Modular Monolith: a single deployable unit with strict internal module boundaries \(e.g., package-per-bounded-context with enforced import rules\). Extract to services only when deployment cadence, scaling needs, or team autonomy requirements force a split.

Journey Context:
Microservices impose distributed systems complexity \(network failures, distributed transactions, operational overhead, eventual consistency\) that overwhelms small teams \(<10 developers\). A modular monolith allows rapid refactoring, atomic database transactions across modules, and simple deployment while preserving the ability to extract services later when boundaries are proven and the team is larger. The key is enforcing module boundaries \(e.g., via package-private access modifiers or architectural testing tools like ArchUnit\) to prevent tight coupling.
