What this skill covers

Overview

Design a more scalable Next.js + NestJS platform with stricter contracts, cleaner frontend-backend seams, and architecture that can survive real product growth.

Steps & content

2 items

Frontend-backend contracts

Align App Router data boundaries with validated NestJS DTOs and auth flows.

Keep server-only logic on the server, validate payloads at edges, and prevent accidental coupling across layers.

Platform evolution

Grow from a modular monolith toward clearer service boundaries only when they are justified.

Use domain modules, event boundaries, and delivery gates to reduce chaos while the product surface expands.
