WordPress as a backend,
not just a website -
REST, GraphQL, or fully headless.

I build custom REST endpoints, wire up WPGraphQL, and connect WordPress to Next.js, Astro, and mobile apps - using the CMS your editors already know, without shipping WordPress's front end.

"His knowledge and experience in crafting websites is truly commendable. He demonstrates a strong command of the platform."

Which API approach fits your project

REST API Simple, cacheable, works everywhere
WPGraphQL One request, exact fields, ideal for Next.js/Astro
Fully headless WordPress as pure CMS, custom front end

I help you pick the right one for your project instead of defaulting to the most complex option.

Why it matters

WordPress's real strength was never the theme layer

Editors know the WordPress admin. The front end doesn't have to be WordPress's front end.

πŸ–ŠοΈ

Editors keep the CMS they already know

Content teams stay in the familiar WordPress admin and block editor. The front end - React, Next.js, Astro, mobile - is decoupled and can move at its own pace.

🎯

Fetch exactly the data you need

WPGraphQL lets a front end request precisely the fields it needs in one round trip, instead of over-fetching a full REST payload or under-fetching and making N+1 requests.

πŸš€

Front-end performance decoupled from WordPress

A statically-generated or edge-rendered front end can hit near-perfect Core Web Vitals regardless of what plugins are installed in wp-admin.

Common problems I fix

Why teams come to me for API work specifically

πŸ•ΈοΈ

The default REST API exposes too much

Out of the box, WordPress's REST API can leak more than you want (author info, revision data, internal fields). I build scoped custom endpoints and controllers that expose exactly what's needed.

🐌

A React/Next.js app talking directly to admin-ajax

Fragile, undocumented, and usually unauthenticated properly. I replace it with a real REST controller or WPGraphQL schema with proper auth.

πŸ”

No clear authentication strategy

Application Passwords, JWT, or OAuth - each fits different use cases (server-to-server vs. a mobile app vs. a public read-only front end). I pick and implement the right one for your architecture.

WordPress API & headless services

FAQ

Questions about WordPress API & headless work

REST is simpler, well-documented, and cacheable out of the box - a good default for straightforward data needs. WPGraphQL shines when a front end needs precise, nested data in a single request (e.g. a post with its ACF fields, featured image, and related posts together) - common in Next.js and Astro builds. I recommend based on your actual front-end architecture, not by default.

Yes - selectively, via the ACF-to-REST-API integration for REST or WPGraphQL for ACF for GraphQL. I expose only the fields your front end actually consumes rather than dumping the entire field group into every response.

No - and I'll tell you if it isn't. Headless adds real complexity (two codebases, preview mode, revalidation, hosting for both) that only pays off when you need front-end flexibility a WordPress theme genuinely can't give you. For many sites, a well-built Sage 10 theme gets you 90+ PageSpeed without the added architecture.

Depends on the use case: Application Passwords or JWT for server-to-server and mobile-app scenarios, OAuth for third-party integrations, and properly scoped public read-only endpoints for content a headless front end just needs to display.

Yes - I've built this exact setup, including one covered on the blog (headless WordPress with Astro). WordPress stays the editorial CMS your team already knows; the public site is statically generated or edge-rendered from its data.

Depends on the rendering strategy - static generation with on-demand revalidation, edge caching in front of the API, or WordPress object caching for high-traffic endpoints. I set this up as part of the build, not as an afterthought once things get slow.
