As a Senior Full Stack Web Developer with extensive experience in WordPress development, I specialize in building highly customized, scalable, and performance-driven websites tailored to complex business requirements. I have strong expertise in custom theme and plugin development, working deeply with Advanced Custom Fields (ACF), Custom Post Types (CPT), custom taxonomies, dynamic template structures, and Gutenberg block customization. I develop fully structured, reusable, and modular WordPress architectures that allow businesses to manage content efficiently and scale without limitations. Beyond WordPress, I work with PHP, Laravel, JavaScript (ES6+), React.js, and Tailwind CSS to deliver modern, secure, and maintainable applications. Throughout my experience, I have optimized large-scale WordPress websites, refactored legacy codebases, improved database queries, reduced plugin dependency by building custom solutions, and implemented advanced API integrations. I have handled complex WooCommerce customizations, membership systems, custom dashboards, CRM integrations, and third-party service connections. My focus remains on clean coding standards, performance optimization, Core Web Vitals improvement, SEO-friendly architecture, and enterprise-level security practices ensuring every platform is stable, scalable, and built for long-term digital growth.

Sherserve • Full-time

Feb 2019 - Aug 2021 • 2 yrs 6 mos

I manage the complete development lifecycle of websites and web applications from requirement analysis and system architecture to deployment and long-term maintenance. On the frontend, I build modern, responsive, and high-performance interfaces using HTML5, CSS3, JavaScript (ES6+), React.js, Tailwind CSS, and Bootstrap, ensuring pixel-perfect design implementation, cross-browser compatibility, and mobile-first responsiveness. On the backend, I work with PHP and Laravel for building robust, scalable applications, along with WordPress for custom theme and plugin development. I develop RESTful APIs, handle authentication systems, implement business logic, and design scalable architectures. I also manage databases such as MySQL and MongoDB, configure servers and hosting environments, implement version control using Git, and follow secure coding and deployment practices. In this role, I have consistently delivered measurable value by optimizing application performance, improving Core Web Vitals, restructuring database queries for efficiency, reducing unnecessary redirects, and enhancing technical SEO. I have built custom dashboards, integrated third-party services including CRMs and payment gateways, automated workflows through APIs, and resolved complex server and deployment issues. My contributions have resulted in faster, secure, scalable, and conversion-focused platforms that not only function flawlessly but also actively support business growth.
