For devs shipping a Next.js + Postgres app: auth, billing, and a fast launch end to end. — built in-house by Skill Me.
Reach for this when you're building a real Next.js + Supabase/Postgres product and need it production-ready, not just running locally. It carries you from data model and API to OAuth login, Stripe subscriptions, and a fast, Core-Web-Vitals-clean launch - so the full path from schema to shipped feature is covered by one coherent stack instead of stitched-together advice.

- Next.js App Router — Builds and reviews Next.js App Router code - server/client component boundaries, data fetching, caching and revalidation choices, streaming with Suspense, and Server Action mutations - and delivers routes where every dynamic-vs-cached decision is explicit.
- GraphQL Schema — Designs GraphQL schemas and resolvers that scale - domain-modeled types, Relay pagination, DataLoader batching to kill N+1, mutation payloads with typed user errors, and depth/complexity limits that stop abusive queries.
- Database Schema Designer — Designs normalized, constrained, migration-friendly relational schemas - entity modeling, key and type selection, indexes derived from real query patterns, and safe forward/rollback migrations.
- OAuth & Auth Flow — Implements OAuth 2.0, JWT, and session auth correctly with security best practices. (external — see source)
- Stripe Expert — Implements Stripe payments, subscriptions, and webhooks so billing state stays correct - Checkout Sessions, signature-verified idempotent webhook handlers, dunning, and SCA handling.
- Supabase Expert — Builds secure Supabase apps - Row Level Security policies as the authorization layer, schema design against auth.users, Edge Functions for service-role work, realtime subscriptions, and versioned migrations.
- Web Performance — Diagnoses and fixes Core Web Vitals - LCP, INP, and CLS - through an ordered audit procedure with concrete code-level changes for images, fonts, JavaScript, and third-party scripts.
- REST API Design — Designs REST API surfaces - resource naming, HTTP method and status-code semantics, error shapes, pagination, and filtering - and delivers an endpoint spec a consumer can build against without asking questions.
