Freelancer Overview

Electrical Engineer with 10 years of experience in the Brazilian energy sector, complemented by a solid background in Data Science (Python, R, SQL, Power BI) and independent mobile application development (Flutter/Dart). I have hands-on experience working with structured and unstructured data, building analytical dashboards, and applying machine learning concepts to real-world operational problems. My technical foundation enables me to handle complex AI training tasks involving reasoning, code evaluation, and data quality assessment with precision. As an independent app developer under Torlaco Systems, I designed and published AI-assisted features for finance and productivity apps targeting the Brazilian market — giving me practical insight into how AI models behave in production environments. Native Portuguese (Brazilian) speaker with advanced English, I am well-positioned to contribute to NLP and RLHF tasks involving PT-BR language data, a domain with high demand and limited supply of qualified annotators.
