At Compass UOL, I develop and maintain Node.js microservices and Azure Functions that coordinate communication between recommendation engines and Adobe AEM. I also built a Java Spring Boot data-sync service for sensitive data ingestion, with PGP encryption and Elasticsearch indexing.

At Compass UOL, I’ve also integrated back-end services with Genesys to automate customer service flows. Before that, I developed Java and Quarkus REST APIs as a freelancer, and as a Data Engineering Intern at Compass UOL, I optimized AWS data extraction processes, reducing execution time by 30%.
