At Transportes Elizarraráz, I developed an Excel system for tracking vendor invoices, payments, due dates, and outstanding items to support weekly reviews and monthly closings.
I also designed a Google Sheets system that centralized operational information and reduced billing errors by 30%. For Human Resources, I developed a records system that centralized documents for more than 30 employees and made them easier to access and update.
I created standardized administrative forms and documentation, and supported security procedures for employees and vehicles. I also coordinated an employee psychological support service and designed and delivered two employee integration workshops.
