Md Nazmul H.

Top Rated WordPress/PHP backend developer with $40K+ earned across 98 completed Upwork contracts. I build custom WordPress plugins, WooCommerce functionality, PHP/MySQL applications, REST APIs, AI integrations, and complex backend systems when off-the-shelf plugins are not enough. I specialize in: • Custom WordPress plugin development • WooCommerce custom features, checkout and payment logic • PHP/MySQL backend development and database optimization • REST API and third-party API integrations • AI/LLM integrations, AI agents and OpenAI-compatible APIs • WordPress performance, security, malware recovery and complex bug fixing • PrestaShop modules and custom ecommerce integrations My core stack is PHP, MySQL and Vanilla JavaScript. I am comfortable working inside existing production systems, tracing difficult bugs, extending legacy code, building new architecture, and integrating external services. I focus on clean, maintainable code, performance, security and practical business logic—not unnecessary dependencies or page-builder-only solutions. If your WordPress, WooCommerce or PHP project needs real backend engineering, custom code, APIs or AI functionality, send me the requirements.
