At Bancóldex, I implement software test automation for digital channels, reducing execution time by 50% compared with manual testing. I’ve tested Bancóldex projects including neocrédito and Leasing Digital, covering functional, regression, and End-to-End flows.

I also developed Python scripts to validate ETL processes and financial data in the institutional Data Lake, and restructured complex SQL queries to reduce response times by 15%. My work includes translating user stories into test cases and supporting software certification for Open Finance projects.
