Engineering Services

We don't just use Linux, we build it

No matter which stage your project is in, we can support you. Our ongoing contributions to open source keep us aligned with current development, so we deliver efficient and accurate solutions without reinventing the wheel.

With over 20 years of experience, our team consists of senior software engineers, cryptography experts, and active Linux kernel contributors. Because IT security is our other core pillar, everything we build is engineered with security in mind from day one.

Core Engineering Capabilities

Linux Kernel & Driver Development

Custom development at the lowest levels of the operating system. We write, review, and optimize kernel code, device drivers, and bootloaders tailored to your hardware.

Write kernel code, device drivers, and bootloaders
Tailor everything to your specific hardware
Write, review, and optimize code ready for upstream

Real-Time Linux Systems (PREEMPT_RT & Xenomai)

Deterministic, ultra-low latency systems for industrial automation, robotics, and critical control loops. We actively contribute to Xenomai and PREEMPT_RT, so we know the deepest intricacies of real-time scheduling.

Build deterministic, ultra-low latency systems
Tune real-time scheduling, interrupt handling, and jitter
Target industrial automation, robotics, and control loops

Embedded Linux & BSP Engineering

We build robust, reproducible, and secure embedded Linux platforms, with custom Board Support Packages using industry-standard build systems.

Develop custom Board Support Packages (BSPs)
Build with industry-standard systems like Yocto and ELBE
Deliver robust, reproducible, and secure platforms

Filesystem Development & Analysis

We have deep expertise in how filesystems work internally. We help you choose, optimize, and analyze complex Linux filesystems for constrained or high-performance environments.

Choose, optimize, and analyze Linux filesystems
Support deeply embedded and constrained environments
Optimize for high-performance storage

Security Engineering & Architecture

Bridging our two core pillars, we design secure architectures, implement hardware-backed cryptographic solutions, and build systems that are natively hardened against attacks.

Design secure architectures from day one
Implement hardware-backed cryptographic solutions
Harden systems natively against attacks

MVP & PoC Development

We help you prove your concepts quickly and securely. We rapidly prototype secure embedded systems and software architectures so you can validate your hardware and business logic.

Prototype rapidly and securely
Validate hardware and business logic early
Draw on knowledge across multiple technology stacks

Custom Services

If the services above do not fully meet your needs, get in touch to discuss additional work. We are happy to tailor our offerings to your requirements.

How We Solve Engineering Challenges

Your Scenario

"We are building an industrial robotics platform that requires strict, deterministic response times without jitter."

Our Approach

We draw on our deep expertise in Real-Time Linux Systems. We integrate and tune PREEMPT_RT or Xenomai, optimize your drivers, and ensure deterministic execution of critical control loops.

Your Scenario

"We are drowning in technical debt because we maintain thousands of lines of custom, out-of-tree Linux patches."

Our Approach

We deploy our Upstreaming services. As kernel contributors and maintainers, we know exactly how to refactor your code and work with the community to get your patches merged into mainline Linux.

Your Scenario

"Our embedded devices are experiencing data corruption and we need a custom storage solution."

Our Approach

We bring in our Filesystem Development experts. We analyze your flash storage, optimize the filesystem, and implement authenticated, resilient storage.

Your Benefits

In the Linux world, code speaks louder than certifications. Our team maintains several kernel drivers and subsystems and authors industry-standard tools like squashfs-ng and mtd-utils. That close involvement gives us a deep understanding of Linux-based systems, which directly benefits your projects.

Open Source is in Our DNA
We believe in the open source model because we are an active part of it. We work directly with upstream maintainers and communities to engineer sustainable solutions.

Zero Technical Debt
Maintaining large out-of-tree patchsets is a nightmare for your teams. We help you upstream your patches into mainline projects, cutting your long-term maintenance overhead.

Security by Design
Because we are also security auditors and cryptographers, we do not bolt security on at the end. We engineer it into the architecture from day one.

Time to team up

Some customers hire us because they are stuck, others lack the manpower to fulfill their engineering ambitions. No matter the challenge, we get to the bottom of it. The best way to do that is to get to know you and your team and work out the right solution together. Let’s team up and get things done.
