Engineering across the full stack — from the printed circuit board to the cloud.
For decades, BAUER GROUP has built industrial electronics and software in-house. The same organization designs the PCB, writes the microcontroller firmware, develops the Linux kernel driver that exposes it, speaks the fieldbus and IoT protocols, operates a large self-hosted cloud platform, and ships the modern web and .NET applications on top.
This vertical integration — silicon → firmware → driver → fieldbus → edge → cloud → application — lets us own a problem end-to-end: a sensor on a conveyor line, the CAN frame it emits, the USB/Linux bridge that carries it, the service that ingests it, and the web UI an operator uses to act on it — all engineered under one roof.
Our roots reach back to the early 1990s — industrial automations and applications written in Delphi (Object Pascal) running on Windows 3.11 — and that continuity of engineering, 30+ years and counting, still runs through everything we build today.

One bridge, every bus. Our open USB-Multi-Bus-Bridge (RP2350) exposes CAN 2.0B, I²C, SPI, UART/RS232/RS485, 1-Wire, I²S and DMX over USB — with its own framing protocol, a gs_usb/SocketCAN-compatible interface, signed OTA, custom KiCad boards, and a matching Linux kernel driver packaged via DKMS. Firmware in C, userspace tools in Rust.
Fieldbus to enterprise — no black boxes. A hand-written Modbus stack (TCP and RTU, master and slave), a structured CAN messaging API, an MQTT layer, and PLC abstractions (Siemens LOGO!/S7) connect the shop floor directly to our applications. Production conveyor stations — infeed, labeling, carton printing, weighing/sealing, and Pick-by-Light — run on hardware and code we built.
Modern web, done thoroughly. Our accessibility SaaS (WCAG 2.2 AA / BFSG / EN 301 549) ships a scanner, statement generator, API and a widget with first-class integrations for React, Next.js, Vue, Nuxt, Svelte, Angular and Astro — TypeScript monorepos on Turborepo/Vite, plus Shopware, Magento, TYPO3 and a fullstack Shopify app.
A platform we run ourselves. An enterprise .NET foundation on current LTS (FastEndpoints, MassTransit, SignalR, OIDC/Passkeys) and a Python MCP-server framework sit on top of a self-hosted platform of 80+ container stacks (Traefik, NATS, RabbitMQ, EMQX, MinIO, Zitadel, Coolify) provisioned via Ansible, Terraform, NixOS and MAAS.
