👤
Senior🎓
Top SchoolSérgio Hilgert is a Senior Software Engineer and Technical Lead with 10+ years building scalable, resilient fintech and marketplace systems from São Paulo. He combines hands-on engineering in Ruby on Rails, VueJS, PostgreSQL and Kubernetes with cloud-native infrastructure expertise in AWS and Terraform to deliver high-availability payment platforms. As an early technical hire at Lia he architected an intelligent payment router that supported growth from zero to hundreds of thousands of clients and processed millions of transactions. Previously he led engineering at Quero Educação, migrating legacy AWS workloads to Kubernetes, introducing Kafka, and managing teams that kept a million-plus monthly visitors platform running. He mentors engineers, promotes infrastructure-as-code and compliance, and is comfortable oscillating between product discovery and low-level system optimizations. Outside of core roles he’s repeatedly shipped end-to-end products that turned into critical company financial systems—demonstrating both product sense and deep operational ownership.
