Sergiu Dominic — Senior QA Engineer

Summary

Senior QA Engineer with 5+ years of hands-on experience across POS/Fiscal systems, Payment Gateways, Mobile Apps, and Enterprise VOD platforms. Recognised for bridging the gap between hardware and software — validating complex transactional workflows, ensuring 100% fiscal compliance, and catching critical defects before they reach production. Currently making a deliberate transition into automation engineering — actively building skills in Selenium/Java and Cypress/TypeScript with the goal of moving into a full-time SDET or Automation Engineer role.
