While at ABC Inc., I was instrumental in creating an e-commerce mobile app from the ground up. The app aimed to provide customers with an intuitive and seamless shopping experience, resulting in increased conversions and reduced cart abandonment rates. In the initial ideation phase, I carried out market research and competitor analysis to establish our unique value proposition. Following that, I worked closely with UI/UX designers to turn the concept into a practical design, prioritizing user-friendliness. During the development stage, I took a key role in setting sprint objectives and release schedules with the development team. We faced an unforeseen issue with payment gateway integration that caused delays. However, by bringing in an expert consultant and undergoing multiple rounds of testing and iterations, we were able to resolve it. After the launch, the e-commerce app received positive feedback from our customers, achieving a 30% increase in mobile conversions in the first quarter and a 10% reduction in cart abandonment rates.
