About

I am a data scientist and engineer, holding a Ph.D. in Agronomy from São Paulo State University (Unesp), with a focus on statistical modeling of agricultural experiments using linear mixed models. I completed an M.Sc. in Crop, Soil, and Environmental Sciences from the University of Arkansas (USA), with emphasis on genetic improvement and fertilization strategies; a B.Sc. in Information Technology with emphasis on data analysis from the Virtual University of the State of São Paulo (Univesp); and a B.Sc. in Biological Sciences from Vale do Acaraú State University (UVA). I am currently in the final year of a B.Sc. in Data Science at Univesp, focusing on data engineering, machine learning, and large-scale data processing. I have experience in database management, manipulation and analysis of structured and unstructured data, exploratory and business-oriented data analysis, variable selection for statistical models, algorithm development for problem-solving, tool creation for task automation, and the design of complete data pipelines from data collection and cleaning to the implementation of predictive models. In addition to developing ETL/ELT pipelines, I also work on data integration via APIs and the orchestration of workflows in distributed environments. I have hands-on experience with Big Data tools, including Hadoop and Spark, as well as agile software development methodologies. I leverage strong analytical skills to solve complex problems involving large volumes of heterogeneous data. I also work on implementing scalable architectures and using cloud services and solutions, which allows me to develop web applications and implement secure and scalable data storage and processing solutions.

I am currently a Data Science Analyst at the Forests, Land Use & Agriculture Program at WRI Brasil, where I design and implement data engineering solutions, maintaining APIs and ETL pipelines optimized for geospatial data processing. As part of the Data & Monitoring Management team, I focus on organizing, processing, and analyzing complex datasets both geospatial and tabular to develop tools and methodologies that support evidence-based decision-making in forest restoration, sustainable land use, and environmental monitoring.

Education

I hold a Ph.D. in Agronomy from the Universidade Estadual Paulista (Unesp), where I specialized in linear mixed models applied to agricultural and biological experiments, focusing on the influence of covariance structures on estimator precision and accuracy. I also earned an M.Sc. in Crop, Soil, and Environmental Sciences from the University of Arkansas (UARK), with research centered on enhancing winter wheat productivity through advanced genetic improvement and fertilization strategies. In addition, I hold a B.Sc. in Information Technology from Univesp and a B.Sc. in Biological Sciences from Universidade Estadual Vale do Acaraú, with a specialization in crop production systems in semi-arid agroecosystems.
