About
I’m a frontend developer with 9 years of hands-on experience building fast, accessible, and scalable web applications. I specialize in JavaScript (React, Next.js, TypeScript) and advanced WordPress/WooCommerce development – including custom themes, plugins, and backend integrations in PHP.
I write clean, maintainable code with a focus on component-based architecture, performance, and usability. I’m skilled in tools like Figma, Adobe Photoshop, and Illustrator, which helps me collaborate smoothly with design teams, optimize visual assets, and contribute creatively to projects. I speak fluent English and communicate confidently with international clients and cross-functional teams – from developers to marketers and designers.
