Rockstar🎓
Top SchoolAlexei Kornienko is a Rust developer and senior software engineer with 14 years of experience building high-performance, cloud-native systems and leading DevOps teams from Ukraine. He combines deep backend expertise (Python, Rust, C++) with hands-on DevOps—designing CI/CD, Kubernetes orchestration, and self-hosted production clusters that sustain high-throughput workloads. Alexei has significant OpenStack experience and contributed tracing and deployment enhancements to the Rally benchmarking tool, and he’s worked on core ØMQ functionality in Rust, highlighting a strong systems and networking focus. As a solutions architect and team lead he has migrated legacy services to async Python, implemented autoscaling on AWS EKS, and delivered storage-backed services handling hundreds of durable writes per second. He brings a pragmatic blend of low-level protocol work and operational reliability, and often surfaces observability and tracing improvements that reveal hidden performance issues.
