Utilized React + Redux + Duck, ExpressJS, NodeJS, PostgreSQL, and .Net Core to create a robust application.

    In my role in the finance department, I developed a finance system to manage user payments for "Universidad de Quintana Roo" through online payment methods, transfers, or deposits. This system allows students, aspirants, and the public to generate payment references to access services or products offered by the university. My responsibilities included processing payments in multiple backend tables to ensure they were marked as "paid" across the university's various systems. Additionally, I implemented a payroll API system called "multipagos," which enabled users to make payments and receive callback information, enhancing the overall payment processing experience. I also modified existing flows within the Sales Force (SalesAPI) in PracticeP
