Database Engineering

WooCommerce High-Performance Order Storage (HPOS)

Migrate away from post-meta table lockups into dedicated indexed order tables designed for 100,000+ daily transactions.

Relational Order Architecture

Dedicated SQL tables (`wp_wc_orders`, `wp_wc_order_addresses`, `wp_wc_order_operational_data`) eliminate 40+ EAV row lookups per checkout.

Non-Locking Index Strategies

Composite index architectures on `(customer_id, date_created_gmt)` ensure checkout and order lookup queries resolve in sub-12ms.

Zero Downtime Synchronous Sync

Dual-run background synchronization verifies complete data integrity before flipping master table pointers.

schema_benchmark.sql BENCHMARK: 8.4x SPEEDUP 
-- High-Performance Order Storage Indexing
ALTER TABLE `wp_wc_orders`
  ADD INDEX `idx_status_date` (`status`, `date_created_gmt`),
  ADD INDEX `idx_customer_orders` (`customer_id`, `id`);

-- Query Execution Plan Comparison:
/* Legacy wp_postmeta EAV: 840ms (Table scan 2.4M rows) */
/* HPOS Composite Index:   11.2ms (Using index, 1 row)  */
SELECT id, status, total_amount, currency
FROM `wp_wc_orders`
WHERE customer_id = 49201 AND status = 'wc-completed'
ORDER BY date_created_gmt DESC LIMIT 20;
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.

Agile Quality Assurance

Our Predictable 6-Stage Service Delivery Lifecycle

From initial architectural discovery to ongoing production SLAs, every milestone is managed with structured Git workflows and transparent communication.

STAGE 01 // AUDIT

Architectural Discovery

Deep review of existing codebase, database slow queries, active plugins, and hosting stack to isolate bottlenecks before writing code.

STAGE 02 // SCOPE

Technical Milestone Scoping

Clear definition of deliverables, architectural specification, Git branching model, and fixed milestone commitments with zero hidden costs.

STAGE 03 // STAGING

Isolated Staging Setup

Replication of production on protected staging. Zero code editing on live sites; sanitized databases ensure complete customer privacy.

STAGE 04 // DEVELOP

Agile Sprint Development

Daily commits directly to your private GitHub or GitLab repositories. Adherence to strict PHP 8.2 typing, WPCS standards, and Slack standups.

STAGE 05 // QA & TEST

Automated QA & Security

Core Web Vitals profiling, OWASP Top 10 vulnerability verification, cross-browser responsive checks, and database stress tests.

STAGE 06 // LAUNCH

Zero-Downtime Release & SLA

Atomic Git deployments, edge Redis cache warmup, a 30-day post-launch bug warranty, and continuous retainers for ongoing feature velocity.

🔒 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.
