Summary
🤩
Rockstar🎓
Top SchoolMoti Cohen is a Principal Software Engineer based in Israel with over 8 years of professional experience and a deeper engineering career spanning embedded, driver, firmware, security, and distributed systems roles. Currently at Redis, he contributes to one of the most widely used in-memory databases, focusing on Sentinel stability, memory allocation optimizations, and resilience around reconnections and timeouts. His background includes security software at CyberArk, WiFi driver development at Intel, and storage firmware at Broadcom, giving him a rare blend of low-level systems expertise and large-scale back-end reliability work. A Cum Laude MSc and BSc in Computer Science from Ben-Gurion University underpin his analytical approach to tough debugging and performance problems. Colleagues describe him as a pragmatic refactorer who finds subtle fixes that prevent outages rather than flashy features, and his open-source fixes have improved Redis Sentinel’s robustness in real-world deployments.
