Summary

Rockstar🎓
Top SchoolAlexey Zatelepin is a Staff Software Engineer with 13 years of experience designing and optimizing distributed storage and data-processing systems, currently working on Yandex Database. He specializes in correctness, performance, and pragmatic simplicity, with deep hands-on experience in replication engines, partition balancing, transactions and cluster metadata from contributions to Redpanda and ClickHouse. At Redpanda he was a main contributor to partition balancing and stabilizing replica distribution—work that directly improved cluster performance and resilience in a Kafka-compatible streaming platform. A former lead developer on ClickHouse and long-time Yandex engineer, he combines rigorous applied-math training from MIPT with production-first engineering discipline. Notably, his code focuses as much on race-free recovery and concurrency safety as on throughput, reflecting a preference for elegant, robust solutions over brittle optimizations.
