Engineering Capabilities

Full-stack WordPress development services

We build maintainable, lightning-fast software that grows with your business without locking you into proprietary frameworks.

Custom Gutenberg & Block Themes

Native WordPress block editor (FSE) themes and custom React-powered Gutenberg blocks. Instant sub-second loads without heavy third-party page builders.

Bespoke Plugin Development

Purpose-built plugins tailored to your specific workflow. Replace 15 disjointed, slow plugins with one lightweight, secure, and fully documented solution.

WooCommerce Custom Engineering

Custom multi-step checkouts, B2B wholesale pricing rules, dynamic subscription models, and high-concurrency database optimizations for high-volume stores.

REST API & Webhook Integrations

Seamless two-way data sync between WordPress and your CRM, ERP, payment gateways, mobile applications, or proprietary SaaS backends.

Complex Database Migrations

Safe migrations across hosts, database charset repairs, Multisite conversions, and decoupled/headless WordPress setups (Next.js, Nuxt, Astro).

Code Audits & Refactoring

We dissect buggy themes, resolve fatal PHP errors, patch custom plugin security flaws, and refactor legacy code to modern PHP 8.2+ standards.

Questions

Frequently asked development questions

Yes, 100%. Upon completion and final invoice payment, all intellectual property, Git repositories, custom theme code, and plugin source code belong completely to you. We never lock you into proprietary platforms.

Yes. We frequently step into existing WordPress projects to audit code, fix bugs, add new features, or refactor legacy plugins. We always perform a code health audit first to ensure we build on a stable foundation.

We strictly follow official WordPress Coding Standards (WPCS) and WordPress VIP best practices for PHP, JavaScript, and HTML/CSS. Every line of code passes through PHP_CodeSniffer and automated linters.

All development is isolated on password-protected staging servers using Git version control. Once features are approved, we deploy during scheduled maintenance windows with zero downtime for your live visitors.

Every custom development deliverable includes a comprehensive 30-day warranty (60 days on full site builds). If any bug or unexpected conflict arises within the agreed scope, we patch it promptly at zero cost.

We provide direct communication via Slack, email, and scheduled video demos. Retainer and agency clients receive a dedicated Slack channel with direct access to our senior engineering leads.
