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.

What custom WordPress development actually means.

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

A clear process for work that is not always simple.

Start a project brief
  1. Share the requirement

    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.

  2. 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.

  3. Scope the implementation

    We agree on architecture, deliverables, exclusions, responsibilities and review points. The scope makes clear what changes and what stays in place.

  4. 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.

  5. 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.
