GraphQL API Development Agency

Flexible, High-Performance APIs Built in GraphQL

We design and build flexible, type-safe APIs using GraphQL — leveraging Apollo Server, HotChocolate (.NET), database dataloaders, real-time subscriptions, and federated schema stitching.

Growth Obstacles

Problems This Solves

Your mobile app is slow because REST endpoints over-fetch heavy data layouts or require multiple API roundtrips.

Frontend developers are constantly blocked waiting for back-end teams to create custom REST resource paths.

Your server query execution suffers from the N+1 problem, overloading databases under moderate user traffic.

You want to combine multiple microservice APIs under a single client-facing endpoint query gateway.

Methodology

Our Proven Process

Schema & SDL Planning

We design GraphQL type objects, input variables, query schemas, and resolver contracts.

GraphQL Runtime Scaffolding

We setup Apollo Server or HotChocolate (.NET) runtimes, connecting CORS, compression, and error logs.

DataLoaders & Resolver Coding

We write resolver functions and configure DataLoaders to batch database queries and solve N+1 issues.

GraphQL Federation Setup

We stitch subgraph services under a single Apollo Federation Gateway router configuration.

Query Complexity Security Checks

We install security plugins checking query depth, rate limits, and launch the federated gateway.

Frequently Asked Questions

GraphQL allows client apps to request precisely the data they need, avoiding over-fetching and under-fetching. Clients can aggregate multiple resource requests in a single roundtrip, speeding up mobile clients.

The N+1 problem happens when a resolver fetches a parent collection, and then runs additional queries for each child relation. We resolve this using DataLoaders, which intercept resolver requests and batch them into a single SQL IN query.

Apollo Federation is an architecture design to build a single gateway API that aggregates multiple microservice APIs (subgraphs), enabling teams to deploy subgraphs independently while presenting a unified schema.

Yes. GraphQL Subscriptions leverage WebSockets to stream real-time updates from resolvers to connected client listeners.
