Back to original languageAbout Ernesto Javier
I am a Higher Technician in Accounting, Taxes, and Social Security with more than five years of experience in accounting administrative support. I have worked in public institutions, private clinics, and state-owned companies, managing processes such as bank reconciliation, invoicing, account control, document management, and customer service.
I specialize in using tools like Bejerman ONVIO, Tango Gestión, and advanced Excel (pivot tables, macros, formulas), which allows me to optimize financial flows, organize key information, and ensure accuracy in every task.
My professional goal is to collaborate with companies and entrepreneurs who need reliable, efficient, and tailored administrative support. I work with commitment, confidentiality, and a focus on results.
