Backend Patterns Skill

Design scalable, maintainable backend architectures using modern patterns and best practices.

Code examples lean on Next.js App Router + Supabase/Prisma. The patterns are stack-agnostic — adapt ORMs, client libraries, and deploy targets to your detected ecosystem.

CRITICAL: Check Existing First

Before implementing ANY backend pattern, verify:

1. Check existing architecture:

ls -la src/server/ src/api/ app/api/ supabase/functions/ 2>/dev/null
cat package.json | grep -i "prisma\|drizzle\|supabase\|trpc"
