Summary
👤
Senior🎓
Top SchoolKain Kalju is a seasoned infrastructure and site reliability leader with over 12 years of experience building and operating large-scale internet services, now serving as Head of Infrastructure at LHV. He brings deep, hands-on expertise across the full stack—from kernel and networking evolution to distributed object storage, high-throughput databases, and multi-cloud deployments—having worked on systems handling hundreds of thousands of users and 100K+ QPS. A long-time open-source practitioner, Kain’s career traces Linux, containers and observability shifts from their earliest days to modern CI/CD and containerized runtimes, and he pairs that historical perspective with practical SRE leadership at companies like Bolt, Starship, and NFTPort. As co-founder of FlyCom OÜ, he mixes entrepreneurial grit with operational craft, and his hobby work in home automation and IoT shows a curiosity for low-level embedded systems rarely found in senior infra leaders.
