Rockstar🎓
Top SchoolGabriel Erzinger is a Senior Software Engineer with 9 years of experience building high-throughput, distributed backend systems that power payments, card issuing, and large-scale microservices ecosystems. He has led PCI-DSS-certified card manager implementations, architected a PIX payment pipeline handling thousands of transactions per minute, and built DAG-driven saga orchestrators that automated ops and cut churn and human error. At Brex and iFood he drove reliability, migration efforts (Elixir to Kotlin), and integration-test adoption, and helped launch Brex Embedded partnerships that unlocked new revenue. An active backend contributor on open-source projects like the Pitaya game server—where he improved etcd service discovery and bootstrapping—he blends production-hardened systems thinking with pragmatic testing and documentation. Based in São Paulo, he pairs a focus on algorithmic problem-solving with a taste for product impact, and off-hours you might find him refining his tennis backhand or exploring wine regions.
