WordPress expertise: custom, fast and secure websites
WordPress is the most widely used content management system in the world. Its block editor (Gutenberg), full site editing and block themes have transformed how sites are built, while its REST API and WPGraphQL allow it to be used headlessly.
Agencei designs custom WordPress sites: block or classic themes, custom blocks, business plugins, WooCommerce shops and headless architectures with Next.js. We also maintain, secure, optimise and migrate existing sites.
This expertise is for companies that want a site their marketing or editorial teams can edit easily and safely, without giving up performance, security or clean, versioned code that other developers can take over.
Use cases
Marketing and corporate sites
Custom block themes, editable page templates, multilingual setup and adherence to accessibility and SEO best practices.
Custom blocks and plugins
Gutenberg blocks built in React, custom post types, custom fields and dedicated business plugins, without piling up third-party plugins.
WooCommerce shops
Catalogue, payment, shipping, subscriptions and ERP or logistics integrations, with particular attention to cart performance.
Headless WordPress
WordPress as the editing tool, a Next.js frontend for speed and design freedom, revalidation on every publish.
Takeover, hardening and optimisation
Audit of an existing site, plugin cleanup, PHP and WordPress upgrades, caching, images and security hardening.
Migration and hosting
Transfer to suitable hosting, containerisation, CDN and automatic backups with restore drills.

Examples of problems solved
Slow site despite a caching plugin
Profiling with Query Monitor, identifying expensive plugins and queries, object caching, image optimisation and reducing loaded scripts.
Hacked site or modified files
Cleaning infected files, clean reinstall of core and plugins, credential rotation, fixing the original vulnerability and monitoring.
500 error or white screen after an update
Enabling logs, identifying the plugin or theme incompatible with the PHP or WordPress version, then fixing or replacing it.
Block editor unusable for editors
Creating custom blocks and patterns, locking down unnecessary options and documenting templates for the editorial team.
Dependence on a heavy page builder
Progressive migration to native blocks or a block theme, preserving content and URLs.
Frequently asked questions
Is WordPress still a good professional choice?
Yes, provided it is built properly: custom theme, few plugins, suitable hosting, updates kept up to date. Used this way, it remains the most efficient editing tool for most content sites.
Block theme or classic theme?
Block themes offer full site editing and a future-proof foundation. A classic theme remains relevant when taking over an existing site or for very specific needs. We choose based on the project and the team.
When should we go headless?
When performance, a very free design or integration into a larger application come first. For a classic content site, a well-built and well-hosted WordPress is often enough.
How do you secure a WordPress site?
Regular updates, limited and vetted plugins, hardened authentication, correct file permissions, a web application firewall, tested backups and change monitoring.
Do you use off-the-shelf themes or plugins?
Rarely for the theme, which is developed from scratch. For plugins, we favour a small number of recognised, maintained tools and build the rest to avoid conflicts and bloat.
