Generative AI in Bradesco's virtual assistant

Context

BIA, Bradesco's virtual assistant, ran on predictive AI and was being moved to generative AI. The new models were in Python; the bank's services ran on Java.

What I did

I was part of the team that adapted the Python libraries so the Java services could use them. I also delivered features in the Core API, which coordinates more than 50 microservices, and built secured REST APIs with Spring Security and JWT, test-first.

Built with: Java, Spring Boot, Spring Security, Python, JUnit

How it works

Hover, focus or tap a step to see what it does.

Constraint

Everything went through a bank's security requirements, which shaped how every change was designed and reviewed.
