Rockstar🎓
Top SchoolAndrew Berlin is a software engineer with 11 years of experience building high-performance, highly available systems, currently contributing at Cloudflare from the Netherlands. He has strong back-end and storage expertise demonstrated by contributions to the YDB distributed SQL database—optimizing blob storage thresholds and runtime configurations—and by designing transaction processing systems for banking at Solanteq. At Meta he researched JVM bytecode compression and compiler/runtime optimizations, reflecting a blend of low-level performance work and production engineering. Known for pragmatic storage and performance tweaks that matter in large-scale deployments, he pairs an ITMO Computer Science background with hands-on experience across distributed databases, JVM internals, and financial systems.
