Rockstar🎓
Top SchoolAntonio Filipović is a software engineer based in Berlin with six years of experience specializing in databases, distributed systems and C++, currently working on search and pruning at Snowflake. He holds a Master's in Computer Science and has driven production-grade improvements at Memgraph, including a new analytics storage mode that halved import times and memory optimizations that cut some customer workloads from gigabytes to megabytes. Antonio implemented high-availability failover using nuRaft, built a jemalloc-based memory tracker, and designed O(1) batch processing for large migrations—demonstrating a focus on stability and resource efficiency. He contributes to open-source projects like Memgraph, improving C APIs, iterators, and LOAD CSV memory behavior, showing a strong attention to low-level correctness. Comfortable across C++, Python, Typescript and cloud tooling, he combines systems-level rigor with practical application delivery. Colleagues describe him as a hands-on engineer who finds elegant, measurable wins in performance and reliability.
