Rockstar🎓
Top SchoolAntonio Anđelić is an Engineering Manager at ClickHouse with a decade of experience building and leading teams that deliver high-performance data systems. He progressed rapidly through engineering roles into management at ClickHouse after a string of technical leadership positions at Memgraph, where he contributed to core database internals and implemented Bolt protocol support for a production graph database. Antonio blends deep back-end and database engineering expertise with hands-on experience in streaming and query execution pipelines, making him adept at both architecture and low-level optimization. Based in Croatia and holding a Master's in Computer Science from FER, he is comfortable navigating complex distributed systems while mentoring engineers and driving pragmatic delivery. An often-overlooked strength is his history of modifying interpreter and memory-management components, which gives him uncommon insight into performance trade-offs in modern analytic databases.
