At Revelo, I evaluated and validated generative code model outputs, wrote reference solutions, and designed unit tests. I also analyzed failures and documented technical feedback.
On my “Plataforma Steam” project, I processed JSON files through ETL and exploratory data analysis, applied sentiment analysis with NLP, and developed an API deployed on Render. I also created an item-to-item recommendation system.
At DSTGroup, I implemented an AWS data lake with Amazon S3 and automated ETL using AWS Glue and PySpark for incremental loading into a data warehouse. I designed the warehouse in Amazon Redshift and used a VPC to connect it with Power BI and train a machine learning model.
