Software that
runs where it
matters.

From the CAN bus to the cloud. We build the firmware, diagnostics and infrastructure that keep modern vehicles and systems talking.

Capabilities

From silicon to signal to service.

Two decades in production automotive software — the low-level details done right, and the systems around them kept running.

01

CAN & CANopen

Raw bxCAN drivers, CANopen stacks to CiA 301, bus-off recovery and message routing built for real harnesses.

02

AUTOSAR

Classic and Adaptive AUTOSAR — from BSW configuration and RTE down to SOME/IP service behaviour.

03

Embedded Firmware

STM32F4xx on Keil MDK-ARM: register-level drivers, self-test, flash CRC and MISRA-aware C you can ship.

Diagnostics & Logs

DLT log analysis at scale — tracing sleep-inhibit, version-mismatch and timing faults across hundreds of thousands of messages.

05

Infrastructure

Self-hosted, hardened Debian stacks: mail, web, Nextcloud and media — with fallback and automated sync.

Tooling & Scripts

The glue that saves hours: OCR parsers, log converters, batch pipelines and the small automations teams actually use.

People

A small studio, by name.

Work here is done by people you can reach, not a queue. Get to know who you're talking to.

Selected work

Built for the road,
and everything behind it.

ECU firmware, bus drivers, log-analysis tooling, GPS hardware projects and full self-hosted infrastructure. A closer look at representative projects is on its way.
