Nemanja J.

I’m a WordPress developer specializing in custom themes, ACF Pro, and PHP. For 7+ years, I’ve been building and maintaining custom WordPress websites for businesses, agencies, and long-term clients. I’ve developed 150+ WordPress websites from scratch and worked extensively on existing custom WordPress codebases. I focus on custom development rather than page-builder websites. I can take a design or an existing website and turn it into a clean, flexible WordPress implementation that is easy to manage and maintain. ### What I specialize in • Custom WordPress theme development • ACF / ACF Pro and flexible content systems • Gutenberg and custom blocks • Figma/design → custom WordPress • Custom Post Types and taxonomies • Custom templates, queries and WordPress functionality • Custom WordPress plugins • PHP, JavaScript, HTML and CSS • REST API and third-party integrations • WooCommerce customization • WordPress performance and Core Web Vitals • Debugging, maintenance and ongoing development I’m also comfortable joining an existing project and working inside a custom theme built by another developer. I regularly troubleshoot existing code, extend templates, modify ACF structures, fix responsive and functionality issues, and improve performance without disrupting what is already working. ### Why clients hire me • 7+ years of WordPress development experience • 150+ WordPress websites developed • 100+ websites maintained and optimized • 40+ Upwork projects • 100% Job Success Score • Top Rated freelancer • Strong experience with custom WordPress architecture • Reliable communication and independent problem-solving If you need a WordPress developer who understands the underlying code rather than simply configuring plugins or page builders, I’d be happy to discuss your project.
