What I'm looking for

I'm seeking an internship or early-career software role where I can expand my technical expertise and professional experience through full-stack web development, web design, and innovative technologies.

I'm building cloud-operated payroll software for the USA at SAP SuccessFactors Payroll, developing Spring Boot and Java services for complex payroll calculations, reporting, and BSI integration.

Previously at SAP Datasphere's Billing Metrics team, I developed the client-facing BDC Estimator price calculator, optimized backend systems, and expanded product features. I wrote Mocha and Cypress unit and integration tests that maintained over 90% test coverage.

I've also built AI voice and knowledge-quiz features with SAP Innovation Academy and presented the work at SAP AI Day and WOW Week.

At UFRGS, I led AI module development in NetLogo, integrated QGIS mapping, modularized a Python front end, and connected NetLogo, Python, and Mininet-WiFi to simulate complex scenarios. I'm continuing my Computer Engineering degree while pursuing opportunities to grow through full-stack development, web design, and innovative technology.
