Im André Luiz Vale de Araújo, a professional with experience in Database and Data Science. I have a degree in Computer Engineering and a Master's degree in Computational Intelligence from the University of Pernambuco. During my Master's degree, I developed a model for predicting Sepsis in ICUs based on clinical data, using a committee of classifiers.
I work as a Senior DBA at the Court of Justice of Pernambuco and as a Data Scientist in the Bastião project at the same institution. In this project, I worked on creating predictive models for predatory actions in legal proceedings. I used advanced statistical modeling techniques, metrics analysis and visualizations. I have expertise in data pre-processing, filling in missing data, class balancing with SMOTE, and database optimization with intelligent algorithms (PSO, ABC, BRKGA).
In the area of predictive models, I applied Random Forest, Logistic Regression, Decision Trees and MLP to classify data. Developed NLP models to calculate document similarity, using the BERTimbau model to generate embeddings.
My experience includes leadership in data modeling and bank maintenance projects, such as Banco Topázio and CrediBRF, with a focus on volumetrics and migration of large volumes of data. I have skills with DBMSs such as Oracle, PostgreSQL, SQL Server and MySQL, and cloud environments with AWS (S3, RDS, CloudWatch).More...
