[architecture] Microservices versus monolith small team startup architecture premature optimization

Start with a Modular Monolith \(bounded contexts as internal modules with strict interfaces, single deploy unit\) until team size exceeds 10-15 engineers or you need independent deployment scaling; extract services only when a module requires independent deploy velocity or technology stack

Journey Context:
Small teams adopting microservices suffer from distributed system complexity \(network latency, distributed debugging, integration testing\) without the organizational benefits \(Conway's Law\). A Modular Monolith allows code isolation and refactoring without operational overhead. The extraction to services should be driven by deployment velocity needs, not theoretical purity.
