Rostyslav Wirt

I am a Senior WordPress Developer with 10+ years of professional experience building custom WordPress solutions for businesses, startups, and agencies.

My core expertise is custom plugin development, API integrations, and high-performance custom themes. I focus on extending WordPress beyond standard functionality and turning it into a flexible platform for business systems, SaaS products, and content-driven platforms.

I build scalable and maintainable WordPress architectures using clean PHP and modern JavaScript, ensuring that projects remain easy to maintain and extend as businesses grow.

Key areas of expertise include:

Custom WordPress Plugin Development — building complex functionality tailored to business workflows

API Integrations — connecting WordPress with CRMs, payment systems, marketing platforms, and third-party services

Custom Theme Development — lightweight, SEO-friendly themes built for performance and flexibility

WooCommerce Customization — advanced store logic, custom checkout flows, and integrations

Performance Optimization — improving Core Web Vitals, page speed, and database efficiency

SEO-Friendly Architecture — clean markup, optimized loading strategies, and scalable structure

Custom Business Logic — developing WordPress solutions that support real business operations

I specialize in projects where WordPress must function as a customized business platform rather than a simple website. This includes building complex plugins, integrating external systems, and developing custom features that support real business workflows.

My development approach prioritizes clean architecture, performance, security, and long-term maintainability, ensuring that each project remains stable, scalable, and easy to extend.
