I am looking for an experienced WordPress developer who can convert our meticulously prepared static HTML5/CSS3 code into a high-performance custom WordPress theme.
The frontend is almost ready (about 99%): semantic markup, metadata, and multilingual structure (hreflang) are fully implemented. The site is built with a focus on high rankings in Google and AI Overviews (AIO), so page builder solutions are not suitable for us. We need a developer who works with a clean semantic DOM structure and complex JSON-LD graphs.
What needs to be done:
1. Custom theme architecture
Transfer the fully ready responsive HTML5 structure (including complex sections, article, figure, and other elements) into a lightweight custom WordPress theme. It is preferable to use a minimal starter theme (Underscores or Sage) or Gutenberg custom blocks.
2. Dynamic Schema integration via ACF Pro
We already have prepared JSON-LD structures (type: "AboutPage", "Organization", "BlogPosting"). It is necessary to implement a user-friendly admin panel through Advanced Custom Fields (ACF Pro) so that content is automatically and correctly populated into schema structures when creating or editing pages and posts.
3. Preserving SEO structure
It is important to prevent WordPress or plugins from adding unnecessary code, extra div blocks, or conflicting schema data. The structure should remain clean and controlled.
4. Performance optimization
The result must meet the metrics of 95+ in Google Lighthouse / Core Web Vitals (TTFB, CLS, LCP, etc.).
Technical requirements:
- Expert level of WordPress development (custom themes from scratch, without Elementor, Divi, Bricks, and similar builders)
- Deep understanding of semantic HTML5 and modern CSS
- Experience with Advanced Custom Fields (ACF Pro) and complex field structures (including nested JSON-LD, sameAs, knowsAbout, etc.)
- Performance optimization and Core Web Vitals (TTFB, CLS, loading speed)
- Experience with multilingual sites and clean integration of hreflang and translations
Application submission conditions:
Please also include:
- A brief description of your experience with custom WordPress themes and ACF Pro
- A link to a real site built from scratch (not a page builder), along with Google Lighthouse metrics (especially mobile performance)
Project:
- Type: one-time project (with the possibility of further support/updates)
- Scope: 13 pages with already ready responsive HTML
- Work format: remote
