Responsible for managing the digital transformation project and the development team of the system, consisting of three main modules: E-commerce (external and internal sales), payment and recurring management with API interface via sub-acquirers (payment gateway) and anti-fraud systems, as well as a contract management module. My role involved mapping user needs, prioritizing demands, defining the solution and architecture, and overseeing the development through to implementation.When I took over the project, the system had many bugs and lacked visibility into payments. We restructured the system using best practices, resulting in a 40% increase in sales conversion by optimizing the checkout process. I also implemented API integrations, reducing issues to less than 1% and enabling automatic reprocessing. Additionally, we improved the billing process, reducing delinquency by 30% with an effective billing cycle and automated retry attempts.
