Work Experience

Software Developer Mid-Level at Sidia Instituto de Ciência e Tecnologia

July 1, 2022 - Present

Developed a solution for automated validation of features directly within the binary code used in Samsung mobile devices during the pre-release cycle for the Latin American market. The tool analyzes and validates the binary before deployment to physical devices, enabling early detection of regressions and functional issues. This reduced validation time from 2-3 days to approximately 10 minutes, significantly accelerating the release cycle and improving delivery quality. The solution is used by engineers and technical teams to ensure feature integrity and compliance before official rollout. Technologies used include NextJS, Axios, Material-UI, TypeScript, Styled Components, Python, Flask API, BeautifulSoup, Docker, and MongoDB.
