About

As an Intermediate Website Developer, I specialize in creating responsive, user-friendly websites using modern web technologies like HTML, CSS, JavaScript, and PHP. I collaborate with design and UX teams to seamlessly integrate front-end and back-end elements, ensuring an optimized user experience. My focus is on writing clean, efficient, and maintainable code, troubleshooting issues, and ensuring cross-browser compatibility. Previously, as a Website Optimization Specialist, I analyzed website performance using tools like Google Analytics and Lighthouse, implementing strategies to improve page load speed, SEO rankings, and overall site performance. I also have experience as a Backend Web Engineer, where I designed and implemented scalable back-end solutions, managed APIs, and optimized databases. Throughout my career, I’ve worked closely with developers and designers to ensure a smooth, responsive user experience.
