02What I Build5 layers

A website is one layer. I work on all of them.

  1. L1InterfaceWhat the user touches
  2. L2APIThe contract between layers
  3. L3ApplicationWhere the rules live
  4. L4DataWhat has to stay true
  5. L5InfrastructureWhere it actually runs

Interface

Responsive, mobile-first frontends and WordPress templates — built so the markup stays crawlable and the layout stays stable.

API

RESTful APIs, third-party integrations, authentication and webhooks — the seam where most projects either scale or break.

Application

Laravel and Python services carrying the business logic: booking rules, availability, enrollment, permissions, payment flow.

Data

Relational and document data models, designed and then optimised — indexes, query shape, and the schema decisions made early.

Infrastructure

Deployment on Linux VPS with Docker, Gunicorn and Nginx, plus the background jobs and scheduled automation behind the request cycle.

07WordPress6+ years

Six years deep in WordPress — and still one layer of a bigger stack.

Custom themes and plugins, WooCommerce at scale, multi-vendor marketplaces and booking flows — plus the performance and security work that decides whether any of it survives real traffic.

01

Themes & Plugins

Custom themes built from Figma and Adobe XD designs, and custom plugins written for functionality that off-the-shelf tooling could not reach.

  • Custom themes from scratch
  • Custom plugins
  • Gutenberg blocks
  • Custom post types
  • Taxonomies & dynamic filters
  • Hooks, filters & WP REST API

02

Commerce & Marketplaces

Large-scale WooCommerce builds with custom checkout flows, plus multi-vendor rental and booking marketplaces.

  • WooCommerce customisation
  • Custom checkout flows
  • Subscriptions & memberships
  • Payment gateways (Stripe, PayPal, Crypto)
  • Multivendor — Dokan, WCFM
  • Bookings

03

Builders & Toolkit

Fluent across the builder ecosystem clients arrive with, without letting it dictate the architecture underneath.

  • Elementor
  • Divi
  • WPBakery
  • ACF Pro
  • CPT UI
  • WPML
  • Polylang
  • MemberPress
  • BuddyPress

04

Performance & Security

Core Web Vitals work, caching strategy and hardening — the part of a WordPress build that decides whether it survives real traffic.

  • Core Web Vitals
  • Page speed optimisation
  • Caching — WP Rocket, LiteSpeed
  • CDN
  • Security hardening
  • Malware cleanup

WordPress taught me where systems break — in the seams between plugins, in queries nobody indexed, in a checkout that works until it is under load. That is the experience I bring to Laravel and Python work now.

08PhilosophyHow I work

Build for the system, not just the screen.

  1. 01

    Reusable architecture

    Write the piece once, in the place it belongs, so the second and tenth use cost nothing.

  2. 02

    API-first thinking

    Decide the contract between layers before the interface exists — everything downstream depends on it.

  3. 03

    Clean backend logic

    Business rules live in the application layer, not scattered through templates and hooks.

  4. 04

    Performance as a feature

    Core Web Vitals and page speed are treated as requirements, not a pass at the end.

  5. 05

    Scalability & maintainability

    Architecture that survives the next developer, the next feature, and the next traffic campaign.

  6. 06

    SEO-aware, conversion-focused

    Crawlable structure and a path to conversion designed in from the first template.
