Our Systems Expertise

  • From standalone team to leading your team
  • Fixed price or T&M engagements

Systems engineering

We help our clients to build modern, memory-safe systems components with Rust.
Our expertise includes:
Asynchronous programming and network applications including our Rust implementation of the Network Time Protocol.
Building core internet protocol implementations, new internet protocols, and Linux utilities such as sudo in Rust.
Integrating Rust into existing systems using language interoperability and cross-platform tooling.
Performance optimization like the optimization for speed of our zlib implementation, but also optimizing for memory usage and power consumption.
Contributing to Rust itself to add functionality or improve the performance of dependencies we use.

Why choose us?

Infineon Technologies:

Tweedegolf’s Rust ecosystem expertise was a decisive factor in the reliable and effective stabilization of TrustZone feature support for Cortex-M devices. Their close involvement with the Rust project and community made the RFC review process transparent and understandable, giving us the confidence to use the feature in production.

Tiago Manczak
Principal Firmware Engineer - Infineon Technologies

Internet Security Research Group:

Delivering solid results quickly, comes from a team that is focused on the task at hand. That definitely is an aspect of TG's work that we appreciate because it leads to impressive efficiency.

Blogs and cases to judge our experience by

Emergency response

Dutch emergency services (fire brigade, (air) ambulance, police, etc) depend on the P2000 paging system to respond to alarms. This system is from the 90s, making resources and bandwidth extremely limited. We worked on a new Rust implementation, including scheduling and encoding messages for the pagers, in collaboration with our client's engineers, Technolution.

Sudo and su

Sudo and su

For the ISRG, the creators of Let's Encrypt, we implemented sudo-rs, a Rust implementation of the ubiquitous Linux 'sudo' command, critical on open-source operating systems that power the Internet.

The project is a joint effort with Ferrous Systems.

Time synchronization

Running on millions of devices and servers, NTP and PTP are vital building blocks of the Internet and other critical infrastructure. Our initiative, Project Pendulum, provides memory-safe time synchronization.

Funded by Sovereign Tech Fund, Prossimo and NLnet Foundation.

Committed to Rust

Software must become safer, and not just our own. We are committed to consolidating the adoption of Rust:

  • Education

    We developed teach-rs, a ready-to-use university course to help teachers of computer sciences to get their students started with Rust.

  • Open-source work

    We contribute to the community by doing our work open source whenever we can.

  • Advocacy

    We support the community as a silver member of the Rust foundation and as a co-organizer of RustWeek, Europe's largest Rust conference.
