I work as a Senior QA Engineer at Sardine, a fintech focused on fraud prevention and compliance. My day-to-day involves test automation in critical environments where a single failure can mean real financial fraud.

Main stack: Cypress, TypeScript, GitHub Actions, Postman, k6.
ISTQB CTFL certified.

My focus is on shift-left testing, test automation contextualized for fintech, and exploring how AI can make QA smarter — not replacing testers, but amplifying capability.

I also produce technical content in Portuguese for the Brazilian community, in addition to articles in English.
