Profil zawodowy
I am an accountant with 10 years of professional experience, supported by my studies at the University of Economics in Poznań and a Specialist Accounting course from the Association of Accountants in Poland. In recent years, I have held positions as an Accounting Specialist in the Finance Departments of international corporations. My goal is to continuously improve and develop my skills. I possess extensive knowledge in the analysis and periodic review of accounting and inventory documents, particularly using SAP. I have also dealt directly with the accounting of cost documents and the issuance of sales invoices across various programs, enabling me to more accurately identify discrepancies and find solutions to problems. Years of experience in finance and accounting have shown me that responsibilities in financial positions within large corporations provide me with the greatest job satisfaction and motivate me to grow professionally.
