Anton Antonov

Engineering Manager and Principal Software Engineer, focused on developer experience, platform engineering, and distributed systems.

Go practitioner for many years, building distributed systems, sometimes with Raft consensus. Kubernetes practitioner focused on cluster ops, multi-cloud, and security (cert-manager, PKI automation). Nowadays also writing production Rust. I’ve built closed-source platform systems and open-sourced pieces of them along the way — see projects.

By preference: Go, Rust, CockroachDB, Redis, Terraform, and whatever cloud environment the problem actually needs.
