Python developer at CIn/Motorola Project improving device-specific test selection with FastAPI and Python.

Brazil
Message

At CIn/Motorola Project, I develop Python and FastAPI backend features that help testers select test cases based on each device’s requirements. I implemented a system connecting product documentation to test plan generation, reducing unnecessary test executions.

I maintain test selection workflows used by major U.S. mobile network carriers and coordinate regression test executions to support software release quality.

As a Software Development Intern at CIn/Motorola Project, I maintained Python tools and REST APIs for test planning and automation. I deployed solutions on Google Cloud Platform, integrated BigQuery, and built Power BI dashboards for test data analysis.

At Softex, I developed Dart and Flutter features for a cross-platform student academic performance app and implemented its PostgreSQL backend integration using TypeScript and TypeORM. I also research Python solutions related to the SZZ algorithm at Juá Labs (UFRPE) and contribute to CommitChecker, a tool for predicting critical software changes and potential defects.
