Description

I am a front‑end architect specializing in structure‑driven WordPress custom theme development.

My focus is on building lightweight, fast, and long‑lasting “Japan Quality” themes that faithfully reproduce the design while maintaining technical integrity.

Over the past 15+ years, I have contributed to more than 300 website builds.

Architectural Approach

Rather than relying on existing templates, I design a responsibility‑separated theme architecture from scratch based on each project’s requirements.

This approach provides clear, measurable value:

Scalability

A consistent BEM/FLOCSS‑based codebase that remains stable even as content grows, ensuring layouts do not break and future developers never get lost.

Performance

A lightweight, plugin‑minimal custom theme optimized for Core Web Vitals, delivering fast, stable performance in real‑world conditions.

Sustainability

WCAG 2.1‑conscious accessibility and semantic HTML that strengthen technical SEO and long‑term maintainability.

Technical Stack

WordPress Expertise

ACF, Custom Post Types, multilingual architecture (WPML‑ready)

Modern Front‑end

HTML5, CSS3 (Stylus/Sass), JavaScript, PWA integration

Design to Code

Pixel‑perfect implementation from Figma or Adobe XD

Quality Assurance

Clean, well‑documented code that other developers can easily maintain and extend

Message to Partners

Agencies and directors consistently describe my work as

“structurally reliable,” “long‑term friendly,” and “safe to hand over.”

I operate not just as an external contractor, but as an independent front‑end unit that strengthens your production quality through technical leadership and architectural clarity.
