🔧 Technical Deep Dive

GraphQL vs REST: When to Choose

Choose GraphQL when:

  • Multiple clients need different data shapes
  • You want to reduce over-fetching
  • Rapid frontend iteration is critical
  • You need real-time subscriptions

Stick with REST when:

  • Simple CRUD operations
  • Caching requirements are complex
  • Team is unfamiliar with GraphQL
  • HTTP-level caching is important

My GraphQL Stack

Hasura - Instant GraphQL from PostgreSQL

  • Auto-generated CRUD
  • Real-time subscriptions
  • Fine-grained permissions

Custom Implementations

  • Python: Strawberry, Ariadne
  • Node.js: Apollo Server, GraphQL Yoga
  • Type-safe resolvers with code generation

# Flexible Schema Design
type Query {
  document(id: ID!): Document
  documents(
    filter: DocumentFilter
    sort: DocumentSort
    pagination: PaginationInput
  ): DocumentConnection!
  
  # AI-powered search
  searchDocuments(
    query: String!
    semanticSearch: Boolean
    limit: Int
  ): [SearchResult!]!
}

type Document {
  id: ID!
  title: String!
  content: String!
  metadata: JSON
  
  # Lazy-loaded related data
  author: User!
  tags: [Tag!]!

type Subscription {

Performance Optimization

I optimize GraphQL APIs for:

  • N+1 Prevention: DataLoader pattern
  • Query Complexity: Cost analysis and limits
  • Caching: Response and field-level caching
  • Pagination: Cursor-based efficient pagination
  • Subscriptions: Efficient real-time updates

Frequently Asked Questions

How much does it cost to hire a GraphQL developer?

GraphQL developer rates: Junior $50-60/hr, Mid-level $60-90/hr, Senior $100-150/hr. Full-time salaries in US SaaS companies average $155,900/year. Project costs: basic GraphQL API $15,000-30,000, enterprise with federation $50,000-150,000+. Effective rates start at $50/hr with prepaid packages (see /pricing/) with production GraphQL experience at Pipelinepharma.

What is the average GraphQL developer salary in 2025?

GraphQL developer salaries in US: $63,000-225,000/year depending on experience and location. Average in SaaS startups: $155,900/year. Technology sector average: $136,700/year. Senior GraphQL architects command $180,000+. Freelance rates are 30-50% higher than equivalent hourly salary calculations.

GraphQL vs REST API: which should I use in 2025?

Choose GraphQL for: mobile apps (reduce over-fetching), complex UIs with varying data needs, rapid frontend iteration, real-time subscriptions. Choose REST for: simple CRUD, HTTP caching requirements, public APIs, teams new to GraphQL. GraphQL reduces frontend-backend coordination but adds backend complexity. I help evaluate based on your specific needs.

What skills should I look for when hiring a GraphQL developer?

Key skills: schema design, resolver optimization, DataLoader for N+1 prevention, authentication/authorization in GraphQL context, subscription handling, and performance optimization. For enterprise: federation, caching strategies, and security. Look for production experience, GraphQL tutorials don’t cover production challenges.

How do you prevent GraphQL performance problems?

Common GraphQL performance issues: N+1 queries (solved with DataLoader), deep/complex queries (query complexity limits), over-fetching at resolver level (proper field resolution). I implement: query depth limiting, complexity analysis, persistent queries, caching layers, and database query optimization. Unoptimized GraphQL is slower than REST, I ensure production-grade performance.
