Worked on the FOSSBilling/FOSSBilling repository to address a critical issue with the Domain Pricing List, focusing on improving the accuracy and reliability of domain registration and renewal price calculations. Utilized HTML and JavaScript to update the calculation logic, ensuring that pricing options dynamically reflect user selections and that undefined or null renewal prices are handled gracefully. Enhanced the front end by generating and displaying pricing options in real time, which improved the overall user experience and reduced pricing-related support requests. This work demonstrated attention to detail in front end development and contributed to more transparent and accurate domain pricing displays.
