WordPress Development Services
Custom WordPress development for businesses and agencies that have outgrown templates and page builders: plugins, WooCommerce, headless builds, security hardening, and performance work. 31 years writing code, 14 focused on WordPress.
Custom WordPress Plugins
AI integrations, webhooks, outbound API syncs, scheduled automations, custom REST endpoints, and admin tools.
WooCommerce Development
Subscriptions, payment integrations, store credit, loyalty programs, and performance work.
Custom Integrations
Shipping and fulfillment platforms, email marketing tools, e-commerce analytics, ad attribution and conversions APIs, CRMs, and lead routing.
Headless WordPress
WordPress as a content API behind any modern front-end -- static site generators like Hugo, JavaScript frameworks like Next.js, or native apps.
Security & Maintenance
Vulnerability remediation, tested core and plugin updates, and hardening.
Who builds your WordPress project?
One principal engineer handles the project start to finish, from scoping through the handoff documentation.
WordPress projects fail in handoffs: the plugin developer doesn’t talk to the theme developer, the agency PM doesn’t understand the database, and custom code gets bolted onto core in ways that break with the next update.
Each engagement ends with documentation future developers won’t curse you for, written by the person who built the system.
What can 84EM build in WordPress?
Custom plugins, WooCommerce development, custom integrations, headless builds, security hardening, updates, and performance work. 84EM builds the functionality WordPress and the major plugins don’t ship with, coded to WordPress standards with escaping, sanitization, capability checks, and nonce verification on every input.
Custom WordPress Plugin Development
Purpose-built plugins where nothing off the shelf fits: role-based workflows, scheduled automations, admin tools, and REST endpoints for outside systems.
WooCommerce Development
Inventory automation at scale, custom subscription logic, and store credit and rewards. See WooCommerce Development for the full breakdown.
LearnDash Development
Custom course logic and gating rules, integrations LearnDash doesn’t connect to natively, multi-tenant platforms for corporate clients, and reporting its stock dashboard doesn’t provide. See LearnDash Development for details.
Custom Integrations
Connecting WordPress and WooCommerce to the rest of the stack: the shipping, email marketing, analytics, ad attribution, CRM, and lead routing platforms a business already runs on. Webhooks, scheduled syncs, and middleware that handle the edge cases.
Headless WordPress
Editors keep working in WordPress while the public site runs on Hugo, Next.js, or a native app – and the public site is faster to host. More at Headless WordPress Development.
WordPress Security Hardening
File permissions, user roles and capabilities, database and header hardening, and removal of outdated or vulnerable plugins. Ongoing programs run through Website Security.
Updates and Maintenance
Core, plugin, and theme updates tested before they reach the live site, and the failures they cause when nobody tests them: plugin and theme conflicts, PHP errors, and white screens.
Performance
Slow query analysis with specific fixes and caching strategy matched to the hosting environment.
How does a WordPress project run?
Four stages: discovery and scoping, architecture, development and testing, then documentation and handoff. The same engineer handles all four.
Discovery & Scoping
A direct conversation about requirements, hosting environment, and plugin compatibility, ending in a project plan with concrete deliverables.
Architecture
Hooks, filters, REST endpoints, and database design that respect WordPress patterns, with custom architecture where core conventions fall short.
Development & Testing
Built to WordPress coding standards, with automated and manual testing throughout.
Documentation & Handoff
Code documentation, deployment instructions, and direct knowledge transfer backed by 31 years of experience.

Frequently asked questions.
Does 84EM do WordPress development?
Yes. WordPress development has been an 84EM specialty since 2012. Custom plugins, AI integrations, APIs, automation and custom workflows. See case studies for examples.
Should I use WordPress for my project?
WordPress powers over 40% of the web. It's flexible, well-supported, and cost-effective for most sites. It's not ideal for highly interactive applications or specialized performance needs. 84EM provides an honest recommendation based on your actual requirements, not a platform preference.
Is WordPress secure?
Yes, when properly maintained. Security depends on updates, passwords, hosting, and plugins, not WordPress itself. Best practices are implemented on all projects.
Does 84EM provide ongoing maintenance and support?
Yes. Monthly retainers include development, consulting, support, maintenance, and security. See Website Security.
Can 84EM build accessible (ADA/WCAG compliant) websites?
Yes. 84EM targets WCAG 2.2 AA with semantic HTML, ARIA attributes, keyboard navigation, and color contrast compliance.
Do I own the code 84EM writes?
Yes. All custom code is owned by the client, with full repository access, documentation, and no lock-in.
