At Asseco Poland S.A, I validate data received from banking systems before migration and test migration applications to check data transfers and identify functional issues.
I analyze migration errors, report discrepancies to data providers, and coordinate issue resolution. I also manage application change requests, gather requirements, and prioritize enhancements based on business needs.
At Lidl, I managed databases across 18 countries and extracted and transformed data from over 100 sources. I also designed database structures and created PL/SQL packages, procedures, functions, and triggers for new applications.
