What I'm looking for

I’m looking to lead architectural vision while staying hands-on in designing and implementing high-throughput, low-latency solutions that scale, and to turn ambitious product visions into production-ready platforms.

At Percona, I architected Percona Everest from scratch and directed its multi-team engineering execution, delivering the stable GA release 50% ahead of schedule. I also redesigned ClickHouse telemetry storage and query paths, reducing executive dashboard load times from 60 seconds to 2 seconds.

At PortaOne, I architected a Kubernetes-based Plugin Marketplace and helped transform cloud-native delivery. Earlier, I managed engineering teams and worked on carrier-grade telecom systems, including a C++ call-routing engine whose throughput increased 20x after refactoring.
