What we build

GraphQL APIs shaped around what your clients need

Schema-first API for web and mobile

You get one typed GraphQL schema that lets your web and mobile clients request exactly the fields each screen needs, which cuts over-fetching and the pile of one-off endpoints that comes with it. We design the schema with you during discovery, so types, queries and mutations reflect your product's language, and we version changes through deprecation rather than breaking the clients you already ship.

Gateway over your existing services

If your data sits behind several REST services, databases or third-party systems, we build a GraphQL layer on top that resolves across them and gives front-end teams a single entry point. Your current services stay in place, so you avoid a risky rewrite. Our technical architect sets the resolver structure, batching and caching approach so one query does not trigger a flood of backend calls.

Secure, tested and documented

Query depth and complexity limits, authentication, field-level authorisation and rate limiting are designed in from the start, because GraphQL's flexibility needs guardrails. We test resolvers and critical queries against agreed acceptance criteria, then hand over schema documentation your own engineers can build against and extend.

Choose with context

Is GraphQL the right fit for your API?

ConsiderationGraphQL suits bestWe may recommend another approach when
Clients and data needsWeb and mobile clients that each need different slices of the same data, or screens that currently make several REST calls to assemble one view.You have one simple client and a small set of stable endpoints. After scoping, Netofficials will recommend a REST API if it serves you with less overhead.
Existing servicesSeveral back-end services or databases that you want to expose through one typed schema, with a GraphQL layer in front of them.Your integrations are mostly file transfers, webhooks or public endpoints that other parties already consume as REST. We will say so after scoping and suggest keeping that interface.
Team and long-term ownershipSeveral services or data sources sit behind one typed schema that web and mobile clients query, each asking for different fields.Your API is a few simple, resource-shaped endpoints, or relies on straightforward HTTP caching; Netofficials will recommend REST after scoping if it serves you better.
How an engagement runs

From written scope to a GraphQL API you can ship

  1. Discovery

    We map your clients, existing services and data sources, then write down the first-release scope of queries, mutations and integrations.

    You receive
    • Written discovery scope
    • Open schema and data questions
    • Initial estimate with assumptions

    You agree the written scope before design starts

  2. Design

    Our technical architect drafts the GraphQL schema, auth model and resolver approach for you to review before any code is written.

    You receive
    • Draft schema of types, queries and mutations
    • Resolver and data-source plan
    • Security and performance notes

    You approve the schema and architecture notes

  3. Build

    We build resolvers, data loaders and integrations in Agile sprints, and your team can query a staging endpoint at each sprint review.

    You receive
    • Staging GraphQL endpoint
    • Sprint review notes covering schema changes
    • Resolver and query test results

    You review working queries at every sprint

  4. QA

    We test queries, permissions, error handling and query-cost limits against the acceptance criteria you agreed, and log any open issues.

    You receive
    • Acceptance checklist for agreed queries and mutations
    • QA report on security and query performance
    • Issue log with severity and status

    You sign off the GraphQL API against the acceptance criteria agreed in writing.

  5. Release

    Deploy the API to production, then hand over schema documentation and deployment access.

    You receive
    • Production GraphQL API release
    • Schema reference and runbook documentation
    • Deployment access handover

    You confirm handover is complete

Connected architecture

A GraphQL stack that fits your services

LayerExample choicesDecision to review
Schema and gatewaySchema-first GraphQL with Apollo Server or GraphQL Yoga, or a gateway over existing servicesWhich types, queries and mutations clients need, and how the schema can change without breaking existing apps
Resolvers and servicesNode.js with TypeScript, or Python, calling your current REST services, databases and third-party APIsWhere business logic lives, plus batching and caching to avoid slow nested queries
Data and securityNode.js or Python resolvers, PostgreSQL, your existing REST or internal servicesWhich service owns each field, and how resolvers batch data access to avoid N+1 queries
Quality and securitySchema checks, resolver tests, Playwright for key client journeysBreaking-change policy, query depth and cost limits, access rules per field

  • Queries, resolvers and permissions tested against agreed acceptance criteria
  • Query depth, complexity limits and caching planned during design
Ways to work with us

Three ways to engage on your GraphQL API

Project delivery

Fixed-price delivery of a defined GraphQL API, such as a new schema-led API or a gateway over your existing services, suited to teams that want a set scope and a handover.

  • A written discovery scope that fixes the schema boundaries, the services behind it and the acceptance criteria
  • A client-facing review at the end of every sprint, so you see working queries and mutations as they are built
  • Requests outside the agreed scope, such as extra types or new data sources, go through a change request before they affect the plan

Dedicated team

A dedicated India-based team that keeps extending your schema, resolvers and client integrations sprint after sprint, suited to products with a long API roadmap.

  • Engineers matched to your API stack and clients, with a technical architect accountable for schema design and code quality
  • Back-end, schema and QA skills matched to your GraphQL API and the services behind it
  • Source code and IP assigned to you under a contract confirmed before the build begins

Staff augmentation

GraphQL-capable engineers who join your own team to add schema design, resolver or performance skills, suited to teams that already run the API and need more hands.

  • Individual GraphQL engineers who slot into your API or gateway team at short notice
  • Resolvers, schema changes and reviews handled in your repositories, tools and pull request process
  • Communication window and update cadence agreed before the first engineer starts
GraphQL API questions

GraphQL API questions, answered before you enquire

What drives the cost and timeline of a GraphQL API project?

Cost and timeline for a GraphQL API follow the number of types and resolvers, how many existing services or databases the schema must connect to, the authentication and permission rules, and how many web or mobile clients will consume it. Netofficials sets these out in a written discovery scope with an estimate before the build begins, and we offer fixed-price project delivery, a dedicated India-based team or staff augmentation. Send a short brief and we will return questions and a proposed scope.

Is GraphQL the right choice, or would REST serve us better?

GraphQL fits best when several clients need different shapes of the same data, when you want a gateway over fragmented services, or when a typed schema should lead development. A small API with few clients and simple, cacheable resources often suits REST better. Our technical architect reviews this during discovery, and if REST or a mixed approach serves you better, we will recommend it after scoping.

Who owns the schema and source code, and how do we stay in the loop?

You own the schema, resolvers and source code: IP assignment is confirmed in the contract before the build begins. A named delivery lead handles day-to-day progress and communication, and we agree the communication window, meeting schedule and update cadence with you up front. You review working software at the end of every sprint, and at release we hand over documentation and deployment access.

Send a brief for your GraphQL API

Tell us which clients consume your data, which services sit behind them and where the current API slows your teams down. We come back with a written scope, a view on whether GraphQL or REST fits better, and the team to build it. A named delivery lead owns communication from the first reply, and IP assignment is confirmed in the contract before the build begins. If another approach would serve you better, we will say so after scoping.
