API Development

APIs that
other people want to use.

Custom REST and GraphQL APIs, authentication, rate limiting, OpenAPI docs, and generated SDKs. Plus help adopting third-party APIs when buying makes more sense than building. We've shipped APIs that handle six-figure call volumes daily.

What's included

Everything you need, none of the upsell.

Real deliverables, with the boundaries written down. So you know what you're paying for and what counts as extra.

REST

Predictable and documented.

Resource-oriented design, proper HTTP semantics, versioning, and OpenAPI spec. So your consumers actually use it correctly.

GraphQL

When clients need flexibility.

Schema-first, batched, with proper caching and N+1 protection. Good fit for complex client UIs.

Auth

OAuth, API keys, JWT.

Authentication that fits your audience. Internal, partner, or public. Plus rate limiting, abuse detection, and audit logging.

Docs

Reference, guides, examples.

API reference auto-generated from spec. Plus hand-written guides for the workflows your consumers actually do.

How it works

The order we work in.

A clear sequence so you can budget time, money, and risk against the work.

Step 01

Design.

Resource model, endpoints, auth, error handling, and versioning. Reviewed before code starts.

Step 02

Build.

Implementation with tests, observability, and rate limiting. Sandbox available to consumers early.

Step 03

Document.

OpenAPI spec, hand-written guides, working examples, and SDK generation if needed.

Step 04

Operate.

Monitoring, deprecation policy, and changelog discipline. So consumers trust the platform.
