🤩
RockstarBrent Gardner is a pragmatic software engineer with 12 years of experience building distributed systems, databases, and tooling, currently helping Coralogix evolve query capabilities while contributing to Apache projects. He’s an active Rust developer and sponsored contributor to Apache Arrow/DataFusion, having added FlightSQL support to Ballista and implemented interval types, subquery decorrelation, and DML features in DataFusion. Brent combines hands-on systems work—prototype transactional databases and query optimization—with platform-level engineering from his time as Director of Cloud Engineering and staff SDE roles. Comfortable across languages and domains (from IoT and computer vision to large-scale data pipelines), he has a knack for turning benchmarking and API gaps into production-ready features. Based in Fort Collins, he quietly balances open-source stewardship with pragmatic product delivery for small teams scaling into medium-sized companies.
