At ESCAD, I designed and implemented an Excel system for administrative control, bringing order and follow-up to office processes. I also handled petty cash, collections and payments, and advised clients on payment plans.
At SIEC, I managed accounting records for 8 to 10 companies, prepared financial reports in Excel, and verified payroll processes through Siigo. At Universidad Santo Tomás, I coordinated graduate ceremony logistics and managed academic information and administrative requests.
