My background is centered on ML model governance, auditing, and risk management, with hands-on experience validating fraud, AML, and credit risk models under Brazil Central Bank guidelines. I have worked across the full model lifecycle, from development and feature engineering to validation, monitoring, drift analysis, and audit-ready documentation. I am comfortable translating technical findings into clear, defensible recommendations for business stakeholders, compliance teams, and regulators. In addition to validation, I have built predictive models and data pipelines using Python, SQL, Spark, Databricks, and related analytics tools, improving performance and reducing operational effort. I also bring experience in software development and cybersecurity analysis, which strengthens my ability to assess systems holistically and identify technical and governance risks early. ## Skills ### [Python](https://jobicy.com/talent/python.md)[SQL](https://jobicy.com/talent/sql.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Agile](https://jobicy.com/talent/agile.md)[Cybersecurity](https://jobicy.com/talent/cybersecurity.md)[Power BI](https://jobicy.com/talent/power-bi.md)[Data Science](https://jobicy.com/talent/data-science.md)[ETL](https://jobicy.com/talent/etl.md)[Databricks](https://jobicy.com/talent/databricks.md)[Spark](https://jobicy.com/talent/spark.md)[API Development](https://jobicy.com/talent/api-development.md)[Data Governance](https://jobicy.com/talent/data-governance.md)[AML](https://jobicy.com/talent/aml.md)[SAS](https://jobicy.com/talent/sas.md)[Pandas](https://jobicy.com/talent/pandas.md)[scikit learn](https://jobicy.com/talent/scikit-learn.md)[MLOps](https://jobicy.com/talent/mlops.md)[Penetration Testing](https://jobicy.com/talent/penetration-testing.md)[Fraud Detection](https://jobicy.com/talent/fraud-detection.md)[Classification](https://jobicy.com/talent/classification.md)[XGBoost](https://jobicy.com/talent/xgboost.md)[Credit Risk](https://jobicy.com/talent/credit-risk.md)[LightGBM](https://jobicy.com/talent/lightgbm.md)[Random Forest](https://jobicy.com/talent/random-forest.md)[SHAP](https://jobicy.com/talent/shap.md)[LIME](https://jobicy.com/talent/lime.md) ## Tech Stack & Tools ### Application Hosting [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/azure/azure-original.svg) Azure](https://jobicy.com/talent?tool=azure.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/hadoop/hadoop-original.svg) Apache Hadoop](https://jobicy.com/talent?tool=hadoop.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/javascript/javascript-original.svg) JavaScript](https://jobicy.com/talent?tool=javascript.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/python/python-original.svg) Python](https://jobicy.com/talent?tool=python.md) ## Experience Data Scientist — Model Validation & Development @ Banco Bradesco Jun 2021 - Present Worked in a dual role validating high-risk ML models and developing predictive models for business support.
