Engaged in a maintenance project for a PHP 7 (CodeIgniter 3) + HTML 5 website. This involved maintaining user registration, online purchasing, and Stripe-based online payment functions. We provided continuous support and improvement, including bug fixes, feature additions, and API integrations. Our work spanned both frontend and backend development, ensuring the website's responsiveness and seamless server management. We successfully integrated Stripe and Google Analytics to enhance the website's capabilities.
