Rockstar🎓
Top SchoolYun Park is a seasoned engineering leader and founder with 11 years of experience building scalable cloud and AI systems, currently serving as CTO and Co-Founder of TierZero, an AI platform that automates incident response and reliability for production systems. Previously engineer #25 at Databricks, he led AI Agent Framework and model serving efforts and scaled a 40-person organization responsible for enterprise admin products like identity, billing, and cloud security. He blends hands-on backend development (notably Spring Boot and JPA best-practices work on his GitHub) with product-facing systems design, shipping both ML-serving infrastructure and mission-critical platform features. Known for turning operational pain points into automated workflows, he focuses on pragmatic, test-driven engineering that reduces incident toil. Based in San Francisco and educated at UC Berkeley, Yun brings startup grit and large-scale engineering rigor to building reliable AI-first tooling. An interesting detail: he pairs deep platform leadership with active repo-level contributions documenting practical Spring and JPA learnings for other engineers.
