// 02_services & capabilities

Backend solutions engineered for high performance.

From bespoke Gutenberg blocks and high-traffic WooCommerce architectures to Redis caching and headless CMS solutions - explore how I build software that scales reliably.

CMS ENGINEERING

Custom WordPress & Gutenberg Block Development

Tailored WordPress engineering without visual builder bloat. I build custom themes from scratch using Full Site Editing (FSE), custom block structures with ACF Pro, and scalable post hierarchies.

  • Custom Gutenberg Blocks: React-backed and ACF Pro native blocks that give editorial teams complete design fidelity.
  • Custom Post Types & Taxonomies: Relational content models designed for structured data queries and faceted filtering.
  • Zero Bloat Architecture: Eliminating heavy 3rd-party page builders for pure speed and clean DOM markup.

BACKEND ARCHITECTURE

PHP Architecture & REST API Engineering

Clean object-oriented PHP 8.x backend logic, high-throughput REST API controllers, webhook event listeners, and MySQL database index tuning.

  • REST API Controllers: Secure, versioned endpoints (`/wp-json/api/v1`) with HMAC token validation and rate limiting.
  • CRM & ERP Integrations: Bidirectional data synchronization connecting web platforms with HubSpot, Salesforce, Stripe, and Zapier.
  • Database Optimization: MySQL slow-query refactoring, composite indexing, and normalized schemas.

PERFORMANCE & SCALE

Core Web Vitals & Server Caching Optimization

Full-stack speed engineering designed to achieve 95+ Google Lighthouse scores, under 100ms TTFB, and zero Cumulative Layout Shift (CLS).

  • Object Caching: Redis in-memory key-value caching eliminating redundant database queries on high-traffic pages.
  • Server Stack Tuning: OPcache memory allocation, PHP-FPM pool optimization, and NGINX microcaching rules.
  • Edge CDN Delivery: Cloudflare edge caching, image optimization pipelines (WebP/AVIF), and script deferral.

E-COMMERCE

WooCommerce Engineering & Custom Store Architecture

High-converting e-commerce engines with streamlined checkouts, custom product bundle logic, dynamic shipping rules, and payment gateways.

  • Frictionless Checkout: Single-page AJAX checkouts reducing cart drop-off on mobile devices.
  • Custom Product Engines: Subscription engines, tiered wholesale pricing, and inventory sync APIs.
  • Security & PCI Compliance: Hardened transaction flows and webhook reconciliation.
