A WordPress engineer
who stays on your site.
Custom themes, plugins, membership and booking builds, integrations, and the backlog you've been putting off. You get a named engineer instead of a different contractor every project.
WordPress is easy to start
and expensive to keep.
Nothing about the first year is hard. Someone installs a theme, adds the plugins that solve each problem as it comes up, and the site does what you need. The bill for that arrives later, in the form of thirty-eight plugins, a child theme nobody documented, and a snippet in functions.php that no one is willing to delete.
So you hire a freelancer for one change. They do it and move on. Six months later something related breaks, and the next person opens the codebase cold and quotes you for the time it takes to understand a decision the last one made and didn't write down. The cost of every change includes the cost of onboarding somebody into your site, and it never amortizes.
The expensive part isn't the development. It's starting over every time.
WordPress work that
survives the next update.
Built against WordPress's own hooks and APIs rather than around them, tested on staging, and shipped with a rollback path.
Custom Themes and Block Work
Block themes, patterns, and editor experiences your team can actually publish with. Built so the people writing the content stop needing a developer to place a section.
Custom Plugins
When no plugin does what you need, or the one that does brings forty features you don't want and a maintenance risk you can't audit. Focused code against WordPress's own hooks and APIs.
Membership, LMS, and Booking
Gated content, course logic, appointment and event scheduling, member tiers, and the renewal and access edge cases that only show up once real people are using it.
Integrations and APIs
CRM, email platform, accounting, and internal systems wired to WordPress with proper error handling, retries, and reconciliation. An integration that silently drops one record in fifty is worse than no integration.
Headless and Content APIs
WordPress as the editing layer behind a Next.js or app front end. REST and GraphQL endpoints shaped around what the front end actually renders, plus preview and cache invalidation that work.
Rescues and Migrations
A site the last developer left mid-build, a theme forked so long ago it no longer gets updates, or a move off Squarespace, Wix, or Drupal. Content and URLs moved with redirects mapped so rankings survive.
Scope, build, ship.
Scope
You describe what you need in plain language. We come back with what it involves, what it touches, and what it costs, plus anything in your current setup that would make it harder than it should be.
Build
A named engineer builds it on staging. You see progress as it goes rather than at the end, and anything touching auth, user data, or payments gets reviewed before it ships.
Ship and Keep
Deployed with a rollback path and verified on the live site. The engineer who built it stays on your site, so the next request doesn't start with someone relearning your codebase.
Running a store?
Checkout, subscriptions, product types, and payment gateways are a different kind of risk from the rest of WordPress, and they get scoped and reviewed differently. That work has its own team and its own page.
