Summary

Senior🎓
Top SchoolŽilvinas Urbonas is a Senior Director of Engineering with 13 years of hands-on full-stack experience and a decade focused on cloud-native systems, infrastructure automation, and Kubernetes cost optimization. He rose through multiple leadership roles at Cast AI—from founding engineer to senior director—building autoscalers, workload optimizers, cost reporting, and AI/ML enablers that bridge ML workflows and cloud efficiency. Comfortable shipping both front-end and back-end solutions, he has a strong track record in product-facing features, production support and architecting cost-sensitive platforms for scale. Prior roles in fintech and property tech (Railsbank, Hostmaker, INVENTI) sharpened his skills in payments, banking integrations and customer-facing systems. Based in Lithuania, he combines engineering management training with practical product delivery and a personal habit of testing ideas outside work—often on a gravel bike or a long run—so he brings curiosity and endurance to technical and organizational challenges.
