Block Architecture

The Foundation of an Enterprise Block Theme

We eliminate the multi-megabyte footprint of visual builders while empowering marketing teams with modular, brand-consistent editing blocks.

FSE // TEMPLATES

Full Site Editing Hierarchy

Standardized HTML template parts (`header.html`, `footer.html`, `single.html`) providing seamless visual site editing in the WordPress admin.

TOKENS // THEME.JSON

Centralized Design Tokens

Global styling rules defined in `theme.json` enforcing typography scales, color contrast, and spacing presets across all blocks.

PATTERNS // BLOCKS

Custom Block Patterns

Pre-designed, conversion-optimized sections (heroes, testimonials, pricing cards, telemetry) ready for drag-and-drop editorial composition.

FLUID // CLAMP

Fluid Responsive Typography

Mathematical CSS `clamp()` rules that smoothly scale headings and copy between 320px mobile viewports and 1920px ultrawide screens.

PERF // CWV

Core Web Vitals Engineering

Preconnected fonts, asynchronous asset loading, and reserved image dimensions delivering an optimized Google PageSpeed experience.

A11Y // WCAG

Accessible Semantic HTML5

Semantic document landmarks (`

`, `
Theme Engineering Process

From Figma Design System to Production Theme

Structured translation ensuring complete fidelity to your brand guidelines and interaction specifications.

STAGE 01 // AUDIT

Figma System Audit

We audit your component library, typography styles, color tokens, and responsive autolayout rules.

STAGE 02 // TOKENS

theme.json Architecture

Mapping Figma variables directly into WordPress v3 `theme.json` schemas and CSS custom property tokens.

STAGE 03 // PATTERNS

Block Pattern Build

Crafting custom Gutenberg block patterns and FSE template parts with semantic HTML5 and 0KB framework JS.

STAGE 04 // QA

Responsive & A11y QA

Testing across mobile, tablet, and desktop viewports, verifying WCAG 2.2 contrast and keyboard navigation.

STAGE 05 // LAUNCH

Zero-Downtime Release

Atomic theme activation on production with browser cache invalidation and a 30-day post-launch warranty.

Performance Engineering

Core Web Vitals Diagnostics & Telemetry

We eliminate frontend bottlenecks at the browser engine level: CSS containment, script deferral, DOM reduction, and server-side object caching.

LCP 1.12s

Largest Contentful Paint

Target: ≤ 2.5s. Optimized via server-side FastCGI caching, resource hints (`fetchpriority=”high”`), and sub-5KB critical CSS.

INP 48ms

Interaction to Next Paint

Target: ≤ 200ms. Long task breakdown via `requestIdleCallback`, passive event listeners, and elimination of heavy main-thread frameworks.

CLS 0.000

Cumulative Layout Shift

Target: ≤ 0.1. Exact aspect-ratio reservation, inline font-display swap matching fallback font metrics, and zero dynamic ad shifts.

🔒 Bilateral NDA Prior to Call • Zero Spam
01 Who owns the source code created during engagements?

You own 100% of all intellectual property, design assets, and source code from day one. Every line of PHP, JavaScript, and block markup is committed directly to your private version control repositories (GitHub, GitLab, Bitbucket) under your corporate ownership. We claim zero residual rights, zero proprietary vendor lock-in, and provide full transfer upon sprint completion.

02 Do you support Full-Site Editing (FSE) and headless WordPress?

Yes. We engineer bespoke WordPress block themes using native Full-Site Editing (FSE), custom block engines, modular block patterns, and strict theme.json token schemas. For decoupled modern architectures, we build high-speed headless frontends powered by Next.js, Astro, or Remix connected via WPGraphQL or the native WordPress REST API.

03 How does developer vetting and the 14-day sprint evaluation work?

Every developer undergoes rigorous 4-stage screening: live architectural interview, automated WPCS & PHP 8 compliance testing, database optimization challenge, and English communication vetting. All dedicated retainers start with an initial 14-day sprint milestone where you evaluate commit velocity, code quality, and communication firsthand before committing to a longer retainer cycle.

04 How do you handle security and non-disclosure agreements?

We execute bilateral mutual non-disclosure agreements (NDAs) prior to accessing any staging servers, repositories, or technical briefs. Developers work on sanitized local or staging environments with least-privilege database credentials, zero production credentials exposed, and strict adherence to OWASP Top 10 web application security best practices.

05 What tools and agile workflows do your developers integrate with?

Our engineers embed seamlessly into your squad’s daily stack: Slack, Microsoft Teams, Jira, Linear, ClickUp, Asana, GitHub, and GitLab. We participate in daily asynchronous standups, provide structured pull request reviews, and align working sprint hours to European and North American operational schedules.

06 How do you guarantee Core Web Vitals performance and upgrade safety?

We build without visual page-builder bloat, writing clean semantic HTML5, pure CSS variables, and native block markup. All themes are 100% WordPress Core API compliant, ensuring sub-second Largest Contentful Paint (LCP), sub-300ms Time to First Byte (TTFB), and flawless automated updates without breaking backwards compatibility.
