Integration Engineering / GraphQL API
GraphQL API Development
GraphQL lets web and mobile clients fetch exactly the data they need in one request — but without care it brings slow resolvers, N+1 queries, and expensive queries anyone can send. We design and build GraphQL APIs with efficient resolvers, query limits, and clear schemas.
This Is For You If...
Your web and mobile apps need different data from the same backend
Your GraphQL API has become slow as the schema grew
You're worried about clients sending very expensive queries
You're combining several services behind one GraphQL endpoint
Which Area Matches Your Need?
Ask Yourself | Points Toward |
Are you designing a new GraphQL schema? | Schema Design |
Are queries slow or hitting the database too often? | Resolver Performance |
Can clients send unbounded queries? | Query Security & Limits |
Do you need one graph over many services? | Federation |
GraphQL Services We Offer
Schema Design
Types, queries, mutations, and pagination designed around client needs and future evolution.
Resolver Performance
DataLoader batching, caching, and query planning to remove N+1 database calls.
Query Security & Limits
Depth and cost limits, persisted queries, and field-level authorization.
Federation
Apollo Federation or schema stitching to combine services into one graph.
What We Need From You
What to Share | Why It Helps |
Client apps and their data needs | Drives schema design |
Existing schema and resolvers | Shows performance issues |
Backend services and databases | Determines resolver design |
Auth model | Shapes field-level access |
Common Mistakes to Avoid
Instinct | Why It Doesn't Help | Do This Instead |
Mirroring the database in the schema | Exposes internals and limits evolution | Design types around client use |
Resolving each field with its own query | Creates N+1 load on the database | Batch with DataLoader |
No query cost limits | One query can overload the server | Enforce depth and cost limits |
Choosing GraphQL for a simple public API | Adds complexity for consumers | Use REST API Design where it fits better |
How It Works
1. Understand clients
What each client needs to fetch
2. Design schema
Types and operations reviewed with you
3. Build resolvers
Efficient, batched, and authorized
4. Add protections
Limits, caching, and monitoring
5. Hand over
Schema docs and guidelines
Why Codersarts
We build GraphQL APIs that stay fast and safe as the schema grows — with performance and security designed in, not patched later.
Turnaround Time
A schema design is typically ready within a few days. Performance reviews of existing APIs are usually delivered within a week.
FAQ
Which GraphQL servers do you use?
Apollo Server, GraphQL Yoga, Hasura, Strawberry, graphql-java, and others.
Can GraphQL sit on top of our REST APIs?
Yes, as a gateway layer while services evolve.
Can you fix slow GraphQL queries?
Yes — usually through batching, caching, and Query Optimization.
Is our project kept confidential?
Yes. Your data, code, and results stay confidential, and an NDA is available on request.
