@mattheuscavati
Multilingual QA and AI data trainer improving localization accuracy and automation.
I am a multilingual QA and localization professional experienced in functional testing, AI data training, and multilingual content operations across PT/ES/IT/EN. I focus on methodical, results-oriented workflows and clear technical documentation.
I have designed automation-first flows and dashboards, created QA checklists and reporting templates, and validated and labeled datasets while performing linguistic reviews and backtesting. My initiatives reduced review time, cut repeated errors, and improved multilingual consistency with glossaries and terminology control.
I prefer fully remote, autonomous roles where I can apply QA, localization and data annotation expertise immediately on a contractor or project basis, with clear metrics and opportunities to streamline processes.
