Robust Software for Critical Systems

We build applications that hold up in production for years: written in Rust, on long-lived, maintainable architecture — and designed to be thoroughly testable.

src/main.rs
#[tokio::main]
async fn main() -> Result<()> {
    let listener = TcpListener
        ::bind("0.0.0.0:8080")
        .await?;
    serve(listener, app()).await?;
    Ok(())
}

Rebuilding a legacy application in Rust

We supported the team through the rebuild: an onion architecture with the domain logic in Rust and Crux as the stable core, UI and device integration as replaceable shells around it, shipped as a multi-platform app built with Flutter.

From proof of concept to production

We stabilized the software for the hardware test lab: reproducible test runs against the real device instead of a model of it — from proof of concept into continuous operation. Handover with documentation and an operations runbook for the in-house team.

Architecture review before rollout

We reviewed the platform's architecture — the dependency analysis done with our own tool, TangleGuard, backed by a review of the code. The result is a report with a prioritized backlog — first and foremost the tests that make stable further development possible.
