WordPress Architecture Since 2009

WordPress.
Built for what you actually need.

Plugins have limits. Your business doesn't. We build custom WordPress solutions that handle enterprise complexity — integrations, custom workflows, real-time data sync, and admin interfaces that work the way your business does.

Custom WordPress Development

When plugins aren't enough, we build it from scratch — cleanly architected and maintainable.

Custom Themes & UI

Purpose-built WordPress themes with clean, semantic HTML and performance-first architecture. Built to your design specification — not a template that's been modified until it breaks.

Themes Performance Design

REST API & Headless

Custom WordPress REST API extensions, GraphQL layers, and headless configurations connecting WordPress to React, Next.js, or mobile front-ends that need a clean data layer.

REST API Headless Next.js

ERP & CRM Integrations

Bidirectional sync between WordPress/WooCommerce and your ERP, CRM, or accounting system. Custom middleware with queue-based architecture, monitoring, and error handling built in.

Integration Middleware Sync

Custom Admin Interfaces

WordPress admin panels and dashboards built for your specific workflows — beyond what standard post types and meta boxes can do. Built for the people who use WordPress daily.

Admin UI Custom Fields Workflow

Subscription & Membership

Complex subscription logic, access control, and membership workflows. Built custom when WooCommerce Subscriptions or off-the-shelf membership plugins can't handle your specific requirements.

Subscriptions Access Control

Performance Engineering

Database query optimization, object caching strategies, CDN integration, and Core Web Vitals improvements for high-traffic WordPress installations that have outgrown their current setup.

Performance Caching Core Web Vitals

Clean Architecture. Maintainable Code.

WordPress built properly is a reliable platform. Built poorly, it becomes technical debt. The difference is in the architecture.

No Plugin Soup

We don't install 40 plugins and hope they don't conflict. We build purpose-specific functionality with minimal dependencies, clean separation of concerns, and predictable behavior you can rely on.

Built to Be Handed Over

Every project we deliver has documented code, sensible hook architecture, and a codebase your team or any competent WordPress developer can understand and extend without needing us.

Scalability By Design

Performance considerations are built in from the start — proper database indexing, query optimization, caching layers, and scalability patterns that handle traffic growth without emergency refactors.

WordPress Doing Heavy Lifting

Enterprise Integration

ERP Inventory Sync

WooCommerce connected to an ERP with near-real-time bidirectional inventory sync. Custom middleware, queue system, and monitoring dashboard. Handles 1,000+ product updates daily without user intervention or manual intervention.

Architecture

Headless WordPress

WordPress as a headless CMS powering a Next.js front-end. Custom REST API extensions, editorial workflow preserved, and performance that dramatically improved over the previous monolithic theme. The content team didn't need to change how they worked.

E-commerce

Complex B2B Checkout

Bespoke WooCommerce checkout flow handling B2B pricing tiers, purchase order workflows, approval gates, and custom shipping calculations for a wholesale distributor. Built where WooCommerce's extension ecosystem had hit its limit.

Nonprofit

Custom Donation Platform

Custom donation management system on WordPress with Stripe integration, recurring donations, CRM sync, donor portal, and automated receipt generation. Replaced a €400/month SaaS tool with a fully owned, maintainable platform.

We work the way serious development should.

Engagements start with a discovery phase — we map your requirements, identify the architecture, and give you a detailed specification before any code is written. No surprises at the end of a six-week build.

We work in staged deliverables with clear milestones. You see working code regularly — not a black box that opens at project end. Most engagements are scoped as fixed-price after discovery, though we also work on retainer for ongoing development and maintenance.

We've been building WordPress professionally since 2009. We know where the platform excels and where its limits are — and we'll tell you honestly when a different architecture would serve you better.

Frequently Asked Questions

Is WordPress suitable for enterprise applications?

WordPress powers over 40% of the web, including major media companies, enterprise intranets, and high-volume e-commerce platforms. The platform's scalability depends on how it's built — not on the platform itself. Properly architected WordPress with appropriate caching, database optimization, and clean code performs well at enterprise scale. The limitations people run into are almost always architectural, not platform constraints.

How do you handle security?

Security starts in the code — no SQL injection vulnerabilities, no arbitrary file inclusion, proper nonce validation, capability checks on every admin action. We follow WordPress Coding Standards and OWASP guidelines. We also configure server-level security, disable unnecessary features, and keep a minimal plugin surface area. Security through obscurity (renaming login URLs) is not our approach — we fix the actual vulnerabilities.

What happens when WordPress core or WooCommerce updates break things?

This is primarily a plugin problem, not a core problem. Core updates rarely break custom code. Plugins break because they hook into undocumented internals. We build using documented hooks and APIs, which means updates behave predictably. For critical sites, we maintain a staging environment and test updates before deploying to production.

Can you work with an existing WordPress site that has technical debt?

Yes, and we do this regularly. We start with a technical audit to map the debt — poorly written plugins, conflicting hooks, database performance issues, outdated patterns. Then we triage: what needs fixing now, what can wait, what needs rebuilding. We give you an honest assessment before committing to any work.

Do you offer ongoing maintenance?

Yes. We offer retainer-based maintenance covering updates, security monitoring, performance oversight, and ongoing development. Alternatively, we can hand off fully and document everything for your internal team or a future agency. We'll recommend based on your team's capacity and the complexity of the build.

How does pricing work?

Projects are typically scoped as fixed-price after a discovery and architecture phase. Discovery ranges from 1–2 weeks and costs €1,500–€3,000. It produces a detailed specification and a fixed project quote. We find this model works better than hourly billing — you know exactly what you're getting and what it costs before any major development starts.
