I’m a results-driven Senior QA Engineer (5+ years) focused on FinTech and compliance, where quality directly impacts trust and risk. I architect scalable end-to-end testing frameworks with Playwright (TypeScript) and apply “Shift-Left” strategies to keep defects out of production. I’ve optimized QA processes with DoD/DoR and CI/CD Quality Gates, cutting production hotfixes by 30% without compromising data integrity.

In my current role at Intertech (Senior Software QA & Automation Engineer), I redefined the QA process for Agile squads by establishing clear Definition of Ready (DoR) and Definition of Done (DoD) criteria, reducing production hotfixes by 30%. I built and maintained a robust automated regression suite using Playwright (TypeScript), transitioning legacy manual tests into a reliable CI/CD-integrated workflow. I also integrated automated Quality Gates into GitLab CI pipelines so developers can catch regressions before merge requests and release cycles accelerate.

My approach is rooted in verification of both behavior and data: I perform rigorous API testing (REST) and SQL-based data validation to ensure strict compliance with banking regulations, along with JSON data integrity checks. I partner with Product Owners to refine acceptance criteria so features are testable and customer-ready from the design phase. Previously, at Vivo Telecommunication as a Test & System Engineer, I led end-to-end quality, bug triage, and root cause analysis on system logs, and at Arte Electronic as a Technical Quality Engineer, I enforced strict technical specifications for zero-error compliance environments.
