What I'm looking for

I’m looking for a quality-focused role where I can verify and enrich information in a large knowledge base, work in English with international teams, and help maintain fast, reliable data through research and careful validation.

I began my professional journey in teaching English and Portuguese and tutoring students of different ages, which built my communication skills and patience. I then spent several years working remotely for an international technology company in research and data validation, where I verified information, resolved inconsistencies, and cross-checked publicly available information in a fast-paced English-speaking environment.

In this role, I worked with a large knowledge base, classifying, enriching, and updating information to improve data quality and accuracy. I also supported project quality by guiding new contributors through initial training, helping them follow workflows, and meeting quality expectations—bringing the same attention to detail I developed through teaching and source validation.
