Maintenance Horizon: Manageable for 6-12 months before refactoring auth/database isolation. Single-language fullstack keeps context switching low while allowing easy migration to dedicated microservices once product-market fit is proven.

Where Early Decisions Cause Regret

Common traps founders encounter 3 to 9 months after choosing the wrong stack prematurely.

⚡ Premature Microservices
Building multi-repo services before PMF multiplies deployment, auth, and schema refactoring overhead by 4x. Keep it a monolith until a single bottleneck demands separation.
📦 Complex NoSQL Schemas
Starting with flexible document stores (Mongo/Dynamo) often causes relational reporting nightmares when tracking subscriptions, workspaces, and team memberships. Postgres handles both JSON and relations smoothly.
🛠 Heavy Custom DevOps
Setting up manual Kubernetes or raw AWS ECS during week 1 wastes critical runway. Managed platforms (Vercel, Render, Railway, Fly.io) save 20+ hours of monthly DevOps for small teams.
