Cristiano Pinheiro
@cristianopinheiro
I build high-volume backend systems, APIs, and cloud workloads with Java and Node.js.
BrazilWhat I'm looking for
At SAP, I develop enterprise software for SAP S/4HANA Financials and optimize cloud execution for REINF government-reporting workloads processing about 5 million files per run.
I improved cloud performance through parallel execution and critical-logic optimization while supporting the move from on-premise to cloud processing. I work daily in English with globally distributed teams and product stakeholders.
Previously at Rech Informatica, I built Java/Spring Boot and TypeScript/Node.js backend services, redesigned an ERP synchronization workload to eliminate recurring customer instability, and improved fiscal-invoice query times from about 60 seconds to roughly 10–15 seconds.
I also build AI-assisted workflow tools that turn natural-language requests into executable actions, alongside delivery automations that reduce repetitive engineering work.
