Anderson Rodrigues

Senior Software Engineer @ Nubank • Distributed Systems & Clojure

Hello! I’m Anderson, a Senior Software Engineer with over 8 years of experience designing, building, and operating high-throughput backend services and distributed systems.

Currently at Nubank, I engineer credit and payment capabilities at scale using Clojure and functional programming principles. My focus includes post-purchase installment financing, automated financial refund workflows, and high-concurrency payment eligibility engines.

Throughout my career, I’ve worked with microservices, event-driven architectures (Kafka), and JVM performance optimization across fintech, banking, and enterprise environments. I also explore AI engineering workflows, having built internal AI-assisted tools for real-time incident diagnostics and evidence collection.
