Summary
👤
Senior🎓
Top SchoolOleksandr Karaberov is a Technical Lead in Core Infrastructure with 11+ years of hands-on experience designing and operating resilient, high-performance distributed systems from Lausanne, Switzerland. He specializes in platform and SRE practices, migrating legacy DBMS platforms to AWS with Infrastructure as Code, and building geographically distributed databases, adaptive video streaming, and event-driven systems using Elixir, Go, and Python. At SpotMe he moved the company off an IBM stack, patched and extended CouchDB’s Erlang core for production needs, and authored monitoring and platform services that improved reliability at scale. A pragmatic engineer who still dives into low-level bug fixes and test automation, he contributes to well-known open-source projects like Apache CouchDB and describes himself wryly as “just another eukaryotic entropy amplifier.”
