Custom plugins, APIs and the glue between your site and your business.
When off-the-shelf plugins stop fitting, I build the thing properly: custom WordPress plugins, REST and GraphQL APIs, dashboards, and integrations with the tools your company already runs on.

A good fit if
Sound familiar?
“Your site needs to talk to a CRM, an ERP and a booking or billing system, and nobody wants to own the integration.”
“A plugin almost does what you need, and the workarounds are now more code than the plugin.”
“You need a members area, a portal or an internal tool on top of WordPress, with real permissions.”
“You have a Node or Next.js front end and WordPress as the content back end, and the seams show.”
What I do
The work
Custom WordPress plugins
Written to WordPress standards, with settings screens, REST endpoints, background jobs and tests. Maintainable by any WordPress developer, not just me.
APIs and headless
REST and GraphQL APIs on WordPress, consumed by Next.js, mobile apps or other systems. Authentication, caching and versioning done properly.
Integrations
HubSpot, Salesforce, Stripe, QuickBooks, Airtable, ERPs and 3PLs. Queued, retried, logged, with a dashboard that shows what synced and what didn’t.
Portals and dashboards
Customer, partner and member areas with role-based access, reporting and exports. Built on WordPress users and capabilities, not a parallel auth system.
Modernising legacy code
Taking over an old custom theme or plugin, adding tests, removing the risky parts, and getting it deployable again.
How it works
From first call to shipped work
Technical discovery
Systems, data flows, volumes and failure modes mapped in a short document with an architecture and a fixed price.
Build in your repo
Pull requests, CI, staging, weekly demos. You see working software every week, not a reveal at the end.
Handover
Documentation, runbooks and a session with your team. You own all of it and can run it without me.
Integrations ship in two to four weeks; apps and portals in six to twelve. Fixed price for defined work, hourly for ongoing engineering. How I work with US teams.
Proof
“Samuel was an excellent developer to work with and a great communicator. Not only did he solve my troubleshooting task with ease, but clearly shows a lot of pride in his work, doing a great job of documenting cleanly all his changes made to my site.”

Questions
Questions I get on the first call
Which stack do you use?
PHP and WordPress for the back end, JavaScript and TypeScript with React or Next.js on the front, Node for services, Postgres or MySQL for data. I pick what your team can maintain.
Do you work inside our existing codebase and tools?
Yes. Your repo, your tracker, your CI. I adapt to your conventions, and I document what I add.
Can you work with our in-house developers?
That is often the best arrangement: I take the hard parts and leave your team with code they understand, plus reviews and pairing if useful.
What does it cost?
Fixed price for defined scope, hourly for ongoing engineering. Discovery is short and priced separately so you can walk away with the plan.
Tell me about the project.
Thirty minutes, free, no pitch. You’ll leave knowing what it would take.
