Rust
I use Rust where reliability and deployable binaries matter more than framework fashion: Axum services, CLIs, and control-plane pieces that have to survive constrained networks. Typical work: shared cores behind CLI + REST + TUI (aurum-rs), gateway-style services (NebulaGrid), DNS helpers (dnstt-kit), and Cargo workflows when crates.io is unreliable (cargo-rust-network-ir). The goal is boring production behavior — clear interfaces, explicit errors, and installers that work offline-ish.
