Rockstar🎓
Top SchoolLuben Karavelov is a seasoned senior software development engineer with 12+ years building large-scale distributed data and database systems, currently driving cloud infrastructure for AWS Lambda from Dublin. He architected and led StreamQuery at AWS—an ultra-high-throughput, real-time streaming analytics engine written in Scala/Akka—and has deep operational expertise with PostgreSQL, Oracle, and large storage fleets. Equally at home in low-level systems, he contributes JNI bindings for zstd and has implemented multithreaded native compression features, reflecting strong C/Rust proficiency alongside Scala and Python. His background spans systems and network administration, DBAs, and machine learning systems, giving him a rare blend of production rigor and research-minded problem solving informed by graduate studies in philosophy. Notably, he combines hands-on implementation of performance-critical native code with leadership in secure, distributed cloud services.
