I support hospital operations through HIS administration, billing workflows, and patient-centered user service.
What I'm looking for
I am an administrative operations and systems specialist with extensive experience connecting business processes, users, and technology. My background includes data validation, ERP/HIS administration, accounts payable and receivable, purchasing, inventory, billing, bank reconciliations, and user support.
At Hospital Guadalupe de Puebla, I supported the implementation and daily operation of HIS-Medsi for hospital administrative, operational, and patient-service workflows. I provided first-line support and respectful follow-up to approximately 120 users across admissions, cashiering, nursing, pharmacy, accounting, and purchasing.
I maintained and validated insurer information, price lists, discount policies, service concepts, cashiering, billing, accounts receivable and payable, purchasing, and inventories. I investigated inconsistencies, documented actions, coordinated corrections, and followed cases through resolution or escalation.
I also developed operational tools using Google Workspace, Google Sheets, and Microsoft Access to improve information organization, shared visibility, financial control, and administrative follow-up.
Earlier in my career, I worked in accounting and administrative operations involving bank reconciliations, invoicing, purchasing, inventory, credit and collections, suppliers, and financial controls.
I am now interested in remote opportunities involving administrative operations, data validation, AI evaluation and training, ERP/HIS support, process analysis, Spanish-language projects, and user support.
