**Role:** WordPress Developer  
**Focus:** WordPress · WooCommerce · Elementor · ACF · PHP · JavaScript

## Clean Code, Solved Problems, Faster Sites

Iryna specializes in developing scalable and maintainable WordPress solutions - working extensively with Elementor, WooCommerce, and custom functionality. She has strong problem-solving skills and regularly handles complex tasks involving dynamic content, AJAX interactions, and performance optimization.

She’s comfortable working with both frontend and backend logic, debugging issues across the full stack, and improving existing codebases. The kind of WordPress developer you call when something stops working and you don’t know why - and the kind you keep around once she fixes it.

At Mettevo, Iryna focuses on clean, efficient solutions and continuously improves her workflow and technical skills. Her work touches everything from custom Elementor Loop Grids and ACF-driven layouts to complex WooCommerce checkout customizations and PageSpeed-critical performance fixes.

## Highlights

- **Full** — Stack debugging - frontend & backend
- **LCP** — CLS · TBT - Core Web Vitals expertise
- **100%** — Maintainable code, no hacks

## Inside WordPress & WooCommerce Development

Iryna handles the parts of WordPress development that other developers avoid: deep customizations, legacy codebases, and the bugs that take three days to track down.

### Custom WordPress Theme Development

Builds custom themes from scratch - semantic markup, optimized templates, modular structure. Editor-friendly back-ends paired with fast, lightweight front-ends. No bloated parent themes, no unnecessary plugins.

### WooCommerce Customization

Customizes checkout flows, payment logic, product templates, and order workflows. From simple field additions to complex multi-step checkouts and custom payment gateway integrations - all without breaking core update compatibility.

### Advanced Elementor Development

Pushes Elementor far beyond drag-and-drop: Loop Grids, dynamic content, ACF integration, custom JavaScript, custom widgets. The kind of Elementor work most developers say isn’t possible.

### Plugin Development & Customization

Builds custom plugins and modifies existing ones cleanly - using hooks and filters instead of editing plugin core. Updates safely, future-proof, and easy to hand off.

### Performance Optimization

Improves LCP, CLS, and TBT scores on existing sites. Audits PageSpeed bottlenecks, optimizes asset loading, defers render-blocking scripts, and ships measurable Core Web Vitals improvements.

### Debugging Complex Issues

Tracks down the bugs nobody else can find - across themes, plugins, JavaScript, AJAX flows, and database queries. Strong analytical thinking applied to the messy reality of real-world WordPress installs.
