At ARCA, Argentina’s national tax and customs authority, I own automated UI test suites end to end for business-critical production applications. I build and maintain Playwright and Selenium coverage that replaces manual regression cycles with repeatable runs and gives teams release confidence in hours instead of days.

I lead UAT, pre-release quality control, exploratory testing, requirements reviews, and defect investigation, connecting complex tax regulations to the systems that implement them. I also write the test cases, acceptance criteria, test data, and SOPs my department relies on, using Claude Code and Cursor daily to speed up authoring, refactoring, and debugging.

Before moving into QA automation, I spent more than a decade in tax, accounting, ERP systems, and ISO auditing. That background helps me spot business-rule risks where incorrect calculations can have legal and financial consequences.
