Senior🎓
Top SchoolVladimir Rodionov is a Senior Staff Software Engineer in the San Francisco Bay Area with over a decade of deep experience building high-performance, memory-efficient backend systems for big data. He has a strong track record in distributed systems and open-source contributions, including work on Apache HBase and Apache Presto, and founded Carrot Data to commercialize his research into cache efficiency. Vladimir designed Memcarrot and membench to push memory and SSD-optimized caching at scale, and more recently created MC/DC to bring Zstandard dictionary compression into Memcached/Redis ecosystems with replication-safe, per-namespace compression and hot dictionary reloads. His background spans Hadoop-era enterprise platforms to modern SQL caching engines, repeatedly driving multi‑x memory savings through custom compression and object-layout optimizations. Known for marrying pragmatic engineering with research-grade performance tuning, he also builds tooling that simulates billion-object workloads to validate real-world gains. Trained in applied mathematics and physics at MIPT, he blends rigorous analysis with hands-on systems craftsmanship.
