BrazilWhat I'm looking for
At Accenture, I developed a feature for deploying and versioning machine-learning models in an anti-fraud engine without restarting the system. Using Java, Spring Boot, Python, and PostgreSQL, I helped improve team efficiency by 80%.
I also developed a dual-confirmation feature for critical actions, using Kafka and a microservices architecture. It reduced failures in those actions by 70%.
At Fderivs, I developed financial insights and real-time risk-monitoring features for stock market assets. I also developed a chat feature integrated with the Llama model, which reduced the need for human support by 95%.
Earlier, at Cresol, I optimized APIs and developed an activity logging system for auditing. I began at EISA, where I worked as an Intern before becoming a Software Engineer and developed features and performance optimizations for the core platform.
