WordPress Development Services

Emyrix builds, maintains, secures, and optimizes WordPress sites — from custom themes and plugins to WooCommerce stores and the integrations behind them. WordPress is PHP, and PHP engineering is what we do. We look beyond the admin panel and plugins to the code, architecture, performance, security, and integrations that keep a site reliable in production.

Overview

What we do, and why it matters

Most of the WordPress work that reaches us is a site somebody else built. It runs, more or less, but it's gotten slow, it's pinned to an old PHP version, or one abandoned plugin is holding up part of the business. Whoever set it up has moved on, and nobody left knows which parts are safe to touch.

So we read it first. Which plugins are load-bearing and which are just installed? What's been changed inside the theme? What was edited directly on the server and will disappear at the next update? You get a plain account of the condition it's in and what we'd do about it, in the order we'd do it. Sometimes that's a rebuild. More often it isn't.

New builds are the other half. A custom theme built as a theme — block templates, editor fields where the people writing content need them, and markup that loads quickly on a phone. Page builders make the first week quicker and the next three years slower.

WooCommerce is where a lot of this ends up: payments, shipping, tax, subscriptions, and the ERP or fulfillment system on the other end of the order. We build on Magento and Shopware too, so when a catalog or operation has genuinely outgrown WooCommerce, we'll say so and tell you what moving would actually involve.

Emyrix LLC is a Massachusetts company working remotely with clients across the country. We work across Eastern, Central, and Pacific hours, with US contracts and invoicing in dollars.

Services

What's included

Custom WordPress themes

Themes built for the site you actually have, with block templates and custom fields set up so your team can publish and edit without opening a ticket. Readable by whoever comes next, and built to survive WordPress core updates.

Custom plugin development

When the functionality you need isn't available in a plugin you want to depend on, we build it. Scoped to the job, kept in version control, tested, and documented — not a snippet pasted into functions.php that disappears with the next theme change.

WooCommerce development

Product, cart, and checkout work on WooCommerce: payment and shipping methods, tax setup, subscriptions, and custom order flows. Including the parts customers never see, like the ERP or 3PL connection that still has to work when an order comes in at midnight.

Taking over an existing site

Inherited a WordPress site from a previous developer or agency? We audit what's there, deal with what's actually urgent, and give you a plan you can put a budget against. A rebuild isn't the price of getting help.

Speed and Core Web Vitals

Slow pages, too much JavaScript, uncached queries, oversized images, and plugins doing work on every request. We measure first, find where the time is really going, and fix what the numbers point at — caching, database queries, PHP version, or front-end weight.

Security, updates, and cleanup

WordPress core, theme, and plugin updates applied and tested instead of postponed, along with hardening around logins, file permissions, and admin access. If the site has already been compromised, we clean up the injected code and address the vulnerability or access point that allowed it in.

Integrations and APIs

Connecting WordPress and WooCommerce to the CRMs, ERPs, email platforms, payment providers, and marketplaces they depend on, with retries, logging, and alerts that keep a broken feed from failing quietly for a week.

Headless WordPress

WordPress as the editing interface behind a React or Next.js front end, using the REST API or GraphQL. A good fit when the content team likes WordPress but the front end needs to be something else.

Hosting, migrations, and maintenance

Migrations between hosts, PHP version upgrades, staging environments, and deployments through CI. Ongoing maintenance can cover updates, monitoring, security fixes, performance work, and the smaller improvements that otherwise sit on a list for a year.

Why Emyrix

What you get working with us

Engineering instead of another plugin

A lot of WordPress problems get solved by installing another plugin. We look at the code first, work out what's actually happening, and fix the underlying problem when that's the better answer. The goal is a site that stays understandable and maintainable instead of accumulating another dependency every time something needs fixing.

We'll tell you when WordPress is the wrong tool

We also build on Magento, Shopware, and Laravel, so we don't have a reason to force every project into WordPress. Sometimes a WooCommerce store should stay exactly where it is and the real problem is hosting, performance, or a poorly built integration. Sometimes it has genuinely outgrown the platform. You get the honest answer either way.

A US company on US hours

Emyrix LLC is registered in Massachusetts. Contracts, invoicing, and working hours are domestic, with overlap across US time zones, so a question doesn't have to wait overnight for an answer.

FAQ

Frequently asked questions

What kind of WordPress work do you take on?

Custom themes and plugins, WooCommerce builds and fixes, speed and security work, integrations, and ongoing maintenance. We also take over sites built by somebody else, which is where a good share of this work starts. If your project is a Magento or Adobe Commerce store, start with our Magento development page instead.

Can you take over a WordPress site somebody else built?

Yes, and it's common. We start by reading the theme, plugins, and whatever has been customized, then tell you honestly what condition the site is in. Urgent problems get dealt with first. You don't have to agree to a rebuild to get help.

Do you build custom plugins, or only configure existing ones?

Both. If a well-maintained plugin does the job, we'll use it — that's usually cheaper than building something ourselves. When there's no suitable plugin, we build the functionality properly: version controlled, tested, and documented so somebody else can maintain it after we hand it over.

Do you work with WooCommerce?

Yes. Payments, shipping, tax, subscriptions, custom checkout and order flows, and integrations with ERP, CRM, and fulfillment systems. We work on Magento and Shopware as well, so we can compare the platforms against your catalog and operation instead of defending one of them.

Should we use WordPress for our project?

Maybe. WordPress is a good fit for many content-driven sites and a lot of WooCommerce businesses, but it isn't the right answer for everything. We'll look at what you're building, who needs to manage it, and what the system needs to do before recommending a platform. If Laravel, Magento, Shopware, or something else makes more sense, we'll tell you.

My WordPress site is slow. Can you fix it?

Usually. We measure before changing anything because the cause is different every time — an underpowered host, a plugin running unnecessary queries, missing page or object caching, an old PHP version, or a front end carrying too much JavaScript and too many unoptimized images. Then we fix what the measurements point at and show you the before and after.

Our site was hacked. Do you clean that up?

Yes. We find and remove malicious code, investigate how it got in, and address the vulnerability or access point that allowed it. That might be an outdated plugin, a compromised administrator account, or stolen hosting credentials. Cleaning up the visible damage without addressing the cause leaves the site vulnerable to being compromised again.

Do you offer ongoing WordPress maintenance?

Yes, as a retainer: core, theme, and plugin updates applied and tested, backups checked, security monitoring, and a queue of smaller improvements. You can also call us when something breaks, though regular maintenance usually prevents small problems from becoming larger ones.

Can WordPress run headless with React?

It can. WordPress stays as the editing interface, while content is delivered through the REST API or GraphQL to a React or Next.js front end. It's useful when a content team is happy with WordPress but the front end has requirements a traditional theme can't meet. It also adds moving parts, so we'll tell you when a well-built theme would do the same job more simply.

How does a project start?

With a conversation about the site, the goal, and the constraints. From there, you get a written scope covering what's included, what isn't, and what we'd tackle first. If we think the work doesn't need us, we'll say so.

How much does a WordPress project cost?

It depends on the state of what exists and what has to be built. After an initial review, we can usually tell you whether the work fits a fixed project, a defined first phase, or ongoing development. We scope the work before asking you to commit to it.
