São Paulo, Brazil
Summary
👤
Senior🎓
Top SchoolEdwi Feitoza is a Senior Systems Engineer specializing in fraud prevention with roughly a decade of production experience building high-availability payment and banking systems across Brazil’s largest financial institutions and marketplaces. He began in hardware and networking as a teen and evolved into a Java- and cloud-focused engineer who routinely designs resilient microservices on AWS, Kubernetes, and observability stacks for transaction-critical platforms. His background spans end-to-end delivery—from low-level infrastructure and performance tuning that cut latency and bandwidth costs, to architecting Open Banking integrations and AI-driven legal automation. Comfortable in high-pressure environments like IBM, Itaú and Caixa, he pairs strong programming and business-analysis skills with practical security and data-science training (MBA in Big Data), making him effective at translating fraud risk into scalable technical controls. An underappreciated strength is his long-term hands-on ops experience, which informs pragmatic, cost-conscious architecture decisions.
