What I'm looking for

I'm seeking junior-level opportunities to apply programming and data analysis to precision agriculture and smart farming.

At SEA Tecnologia, I develop and maintain corporate web applications using React, TypeScript, and Liferay, integrated with REST and GraphQL APIs. I also investigate application defects and take part in code reviews, testing, and production rollouts.

I conceived and developed AgroIA, a personal digital agriculture platform aimed at helping small and medium-sized farmers access AI and data-driven decisions. Its planned features include image-based crop problem diagnosis, agricultural assistance, contextual recommendations, and weather monitoring; I developed its mobile MVP with React Native.

My web development experience also includes building websites and applications as a freelancer with React, Vue, and Next. I'm currently pursuing a graduate specialization in Digital Agriculture at PUCPR, studying Python, data science, machine learning, big data, and precision agriculture.
