How not to end up your app to a hot mess of spaghetti Carbonara
summary
A student-networking app validates its idea with 30 cold emails and 10 replies, builds an MVP in six weeks, lands 4 paying customers and raises $800k pre-seed. Architecture enforces modular business modules, facades for each third‑party tool and an analytics adapter for Mixpanel/GA/Amplitude. Uses React DND, Firebase and a bespoke component storybook flow before extracting a component npm package (a migration that takes five months). A CSS injection bug inflates loads 10,000× and fixing it saved 200KB bundle; lazy chunks use app-versioned hashes plus a service worker to avoid dynamic-import failures.
