Rockstar🎓
Top SchoolIvan Carrero is a seasoned software engineer and founder with 17 years of experience building large, high-performance distributed systems across startups and enterprises. He blends deep systems architecture expertise—from Akka/Scala and Go to Kubernetes and secure CI/CD pipelines—with hands-on product delivery, having led migrations from monoliths to Go microservices and GraphQL/GRPC architectures. At companies like Netflix, VMware and One Concern he drove platform reliability, k8s integrations, and ML workflow orchestration, while at Reverb and BackChat he improved latency and introduced continuous delivery and observability. A long-time open-source contributor and maintainer (notably on json4s, Scalatra, Akka integrations and go-swagger/openapi tooling), he often implements low-level fixes that improve stability and interoperability. He favours pragmatic engineering practices—TDD/BDD, CD and strong team communication—and has repeatedly scaled small teams into mature engineering organizations. Based in Gilroy, CA, he now leads Knub.ai, continuing to focus on Go as his preferred language for combining execution speed with rapid development.
