Senior🎓
Top SchoolChristian Nau is a Lead Principal Software Engineer with 16 years of experience designing and shipping highly available, scalable backend systems for SaaS and enterprise products. Based in San Diego, he specializes in Java, Spring, Hibernate, PostgreSQL and cloud-native patterns—having driven monolith-to-microservice extractions, Pub/Sub-driven asynchronous pipelines, and performance optimizations that materially improved API latency and throughput. He’s led architecture and mentoring efforts across payments, routing, and fare-collection domains, and has deep hands-on experience tuning complex queries and database schemas for both OLTP and read-heavy workloads. Notably, he built a denormalized real-time payments ledger and a Slack onboarding bot that only runs on demand, reflecting a pragmatic focus on operational efficiency and cost-conscious design. Colleagues rely on him for elegant, low-defect implementations and practical systems that scale predictably.
