Custom WordPress development that fits the way your business actually works.
I build custom themes, plugins, Gutenberg blocks and integrations for teams whose requirements no longer fit a ready-made setup. The result is WordPress shaped around the work it needs to do — without turning the site into a pile of exceptions.
Custom WordPress development is the creation or extension of a WordPress website around specific functional, design and content-management requirements. It can include a custom theme, purpose-built plugin, Gutenberg blocks, third-party integrations or new functionality inside an existing site. The goal is not custom code for its own sake, but a cleaner fit than a collection of workarounds can provide.
Custom where it helps. Standard where it already works.
Custom WordPress themes
I turn approved designs or an existing design system into responsive WordPress templates. Reusable components keep the frontend consistent and give editors a clear structure to work with.
Development from approved designs
Reusable, responsive templates
Accessibility-aware frontend implementation
Structured content and editing controls
Custom plugins and site functionality
I build features around the way your business operates. Where an existing plugin provides a sound foundation, I extend it through supported hooks rather than changing files that an update will overwrite.
Custom data and business workflows
User roles and permissions
Dashboards and administrative tools
Maintainable extensions to existing plugins
Gutenberg blocks and editor workflows
I create blocks and patterns for the content your team publishes repeatedly. Sensible controls protect the design while leaving editors enough flexibility to get their work done.
Custom blocks with focused controls
Reusable patterns and templates
Fields organised around real content
Improvements to brittle editing setups
API and third-party integrations
I connect WordPress with external tools and data sources using their documented APIs. Authentication, data mapping and error handling are part of the implementation, so the connection can be maintained after launch.
Business-system connections
Data mapping and synchronisation
Authentication and permissions
Error handling and recovery paths
Development for an existing WordPress site
A new requirement does not always call for a new website. I review the existing setup, identify dependencies and add or replace the relevant parts while preserving what already works.
New features within an existing site
Refactoring unreliable custom components
Template and editor improvements
Dependency and compatibility review
Do you need custom development — or just a better existing solution?
Use an existing solution when…
A maintained plugin covers the requirement cleanly.
Your workflow can adapt without operational friction.
Standard behaviour meets your users’ needs.
The cost and dependency trade-off makes sense.
Consider custom development when…
The feature is central to how your business operates.
Several plugins are imitating one coherent workflow.
Editors or users need specific controls.
An integration follows non-standard data or business rules.
Workarounds create performance, security or maintenance risk.
I do not recommend custom code because it sounds more impressive. I recommend it when it gives the project a clearer, safer or more maintainable route than the available alternatives.
From technical decisions to a clean handover.
Depending on the scope, the work may include:
Requirements review and technical discovery
Review of the existing WordPress setup
Architecture and implementation approach
Theme, plugin, block or integration development
Responsive and accessibility-aware frontend work
Testing across relevant content, user flows and devices
A staging and review workflow
Deployment or handover support
Documentation appropriate to the project
Optional ongoing maintenance, scoped separately
Built around real content, teams and constraints.
A selection of WordPress development projects. Open a case study for the project context and implementation.
Tell me who uses the site, what needs to happen and where the current setup falls short. Existing designs, business rules and known constraints help establish the starting point.
02
Technical discovery
I review the stack, dependencies and technical risks, including whether a maintained existing solution would be a better fit. Any investigation needed before a responsible estimate is made explicit.
03
Scope the implementation
We agree on architecture, deliverables, exclusions, responsibilities and review points. The scope makes clear what changes and what stays in place.
04
Build and test
I develop in the appropriate environment and share progress for review. Testing covers the feature, permissions, relevant devices and the parts of the site it interacts with.
05
Launch and handover
I deploy or deliver the agreed work with proportionate documentation. Your team gets the context needed to edit, maintain and take ownership of the implementation.
The feature needs to work. The site still needs to be workable.
Maintainable foundations
WordPress conventions and clear boundaries make custom code easier to understand, update and hand over.
Security and performance
Permissions, input handling and data access are considered alongside the cost of queries, assets and external requests.
Usable interfaces
Responsive layouts, accessibility-aware controls and a sensible editing experience matter as much as the feature itself.
Future ownership
Compatibility checks and documentation give your team a workable starting point for the next change.
Typical tools include PHP, JavaScript, WordPress APIs, Gutenberg, REST APIs, HTML, CSS and the existing stack your project already depends on.

Questions before we build anything custom.
A custom theme, plugin, Gutenberg block, integration or a focused feature within an existing site can all be custom development. The scope follows your requirements; it does not have to mean rebuilding the entire website.
Yes. I first review the theme, plugins and relevant dependencies, then identify how to add the feature without disrupting working parts. If the existing setup creates a constraint, I explain it before we agree on the implementation.
I compare the requirement with maintained existing options before recommending custom work. A suitable plugin can be the right choice; custom development becomes useful when the available options create awkward workflows, unreliable dependencies or ongoing maintenance problems.
Yes. I can implement approved designs or an existing design system and build reusable Gutenberg blocks, patterns and templates. We agree on the editing controls so your team can update content without having to recreate the design each time.
I assess the API documentation, authentication, available data and business rules before confirming the integration scope. The work can include data mapping, permissions, error handling and a plan for maintaining the connection.
The editorial workflow is part of the scope. We identify what your team needs to change, provide appropriate controls and include documentation proportionate to the project. Changes to the underlying functionality may still need a developer.
I can work with your designer, agency or existing developers. I review requirements, dependencies and responsibilities before estimating; if technical discovery is needed, I separate it from implementation so the proposal can define deliverables, exclusions and review points clearly.
Ongoing maintenance and further development can be agreed separately. Before handover, we clarify ownership, documentation and the next steps for support so you know how future changes will be handled.
