WordPress Developer (Gutenberg Experience Required; Preferred Experience: Local & On-page SEO)
Constantine is very innovative with modern WordPress block development and tools. Performance expert, boosted our PageSpeed Insights scores tremendously for SEO! Created a neat custom design based on a reference site, so we didn't need to have the extra step/cost of designing in Figma. Talented developer, designer and WP admin. Very happy with the work!

The right WordPress development:
FROM BLOATED THEMES TO CLEAN ARCHITECTURE
Most companies struggle with a low-end WordPress developer approach — sites built on heavy builders, patchwork code, and outdated architecture. This results in hidden technical debt: slow performance, fragile layouts, and total dependency on third-party plugins. If your site is hard to scale or maintain, the problem is the foundation, not the platform.
WordPress developer service:
PERFORMANCE REDESIGN & MODERNIZATION
As a Senior WordPress developer, I rebuild inefficient sites into well-structured, performance-oriented modular systems from scratch. I provide a complete modern optimization, redesign, and modernization of your digital infrastructure. This minimizes cost of ownership and ensures your business gets a technical asset with 90-95+ PageSpeed scores.
📩 Make me your WordPress developer, message me now, and let’s perform a WordPress website redesign that turns your project into a clean, high-speed business tool.

I am a WordPress developer and designer specializing in Gutenberg and Full Site Editing (FSE). My work focuses on creating modular design systems, structured data models, reusable blocks, and optimized performance for scalable, maintainable websites.
