Summary
🤩
Rockstar🎓
Top SchoolJure Bajić is a software engineer with 11 years of experience specializing in high-performance database internals and distributed systems, currently advancing vector search and context-aware features in ArangoDB using C++ and RocksDB. He has a proven track record delivering core engine improvements across query planning, indexing, and cluster orchestration, including integrating FAISS for vector search in production cluster settings. Prior work spans Memgraph and Neon contributions, where he fixed low-level storage/read-path bugs, improved serialization and observability, and helped make serverless Postgres and graph databases more reliable at scale. Comfortable in C++ for performance-critical paths and Python for orchestration, he also experiments with Rust and Go—having implemented a Bolt proxy in Go and small Rust solutions. Jure pairs systems-level curiosity with pragmatic engineering: he optimizes perf with profilers, builds CI/CD pipelines, and has hands-on customer integration experience. Outside of code he pursues continuous learning through reading, podcasts, and staying physically active at the gym.
