Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

Research Assistant (WHK), FPGA Development – BrassSense Project at HAW Hamburg / Prof. Peter Schulz
- Real-time tone detection on FPGA (~20 ms latency target) using a filter bank architecture with a fuzzy-logic decision stage, avoiding FFT due to its window-length/frequency-resolution tradeoff.
- Responsible for system integration and architecture.

Robert B.
Last position:
Team Lead; Software Developer at Provider of industrial control systems for manufacturing and digital transformation
Industrial Communication | Proof of Concept: Controller-to-Controller Communication with OPC UA FX
Proof of Concept for OPC UA FX-based controller-to-controller communication between virtual programmable logic controllers (vPLC) on an industrial edge platform. A virtual test environment was set up on Debian Linux in two phases (including VMs and vPLCs), shared-memory communication (real-time information bus) was activated, and the RIB solution was integrated into a customized product firmware (including shared memory and PROFINET support) and deployed in containerized environments (Docker). Additionally, a virtual Ethernet connection was developed to simulate the network topology. Finally, commissioning, functional tests, sample application creation, comprehensive documentation, and customer support were completed.

About the technology
Hardware Description
Device Tree is a data structure that describes hardware to an operating system without requiring platform details to be hard-coded in the kernel. It is widely used with embedded Linux, especially on ARM, PowerPC and RISC-V boards. Device Tree Source files are compiled into Device Tree Blobs that boot firmware and kernels can read.
Board Support
Device Tree experts define CPUs, memory, buses, interrupts, clocks, regulators, GPIO lines and peripherals. They connect these descriptions to Linux drivers through compatible strings, properties and phandle references. Correct hardware modelling is essential when bringing up a new board or adapting an existing board support package.
Tooling And Ecosystem
The work usually spans the Linux kernel source tree, bootloaders and cross-compilation environments. Common formats and tools include DTS and DTSI source files, DTB binaries, the Device Tree Compiler and U-Boot. Strong specialists also understand bindings, schema validation and the Linux driver model.
- Create or extend board-level DTS and DTSI files
- Validate bindings and resolve compiler warnings
- Trace boot logs and inspect live device trees
- Align firmware, kernel and hardware revisions
When Expertise Helps
Companies bring in freelance Device Tree expertise during board bring-up, product maintenance and kernel upgrades. Support is especially useful when a peripheral is not detected, a boot sequence fails, or a vendor description conflicts with upstream conventions. In Germany, this work often supports industrial controls, automotive electronics, robotics and connected devices, with remote collaboration combined with on-site lab access when needed.
Project Deliverables
A specialist may deliver a clean board description, validated binding changes, bootloader configuration and documented hardware dependencies. They can also isolate whether a fault belongs to the schematic, firmware, kernel driver or Device Tree data. Useful handover material includes reproducible build instructions, test evidence and notes for future kernel updates.
Signs Of Quality
Experienced professionals read schematics and kernel code rather than treating Device Tree as a collection of copied properties. They choose established bindings, keep vendor extensions narrow and test changes on real hardware. Look for clear reasoning about boot order, interrupt routing, power domains and the differences between a source description, a compiled blob and the live tree exposed by Linux.
Frequently asked questions
Before you brief your next project: the most common questions about Device Tree.
Device Tree describes hardware components and their relationships so an operating system can initialise them without embedding board-specific details in kernel code. It is commonly used for embedded Linux boards, bootloader handover and hardware variants that share a kernel.
Device Tree separates hardware description from much of the Linux kernel and driver logic. Compared with hard-coded board files, it can make board variants easier to maintain, while still requiring accurate bindings, compatible strings and driver support.
Device Tree projects commonly use DTS source files for board descriptions and DTSI files for reusable includes. The Device Tree Compiler turns these sources into a DTB, also called a Flattened Device Tree Blob, which firmware or the kernel can consume.
Device Tree work benefits from embedded Linux, C, bootloader configuration and Linux driver knowledge. Familiarity with schematics, serial consoles, Git, cross-compilers and hardware debugging helps a specialist connect a software symptom to the underlying board design.
Device Tree projects vary from a focused peripheral change to complete board bring-up. The right specialist should have handled hardware description, kernel integration and testing on real targets that resemble the project’s processor, boot flow and peripherals.
Device Tree changes can often be prepared, reviewed and tested remotely with shared logs, build access and reproducible hardware setups. On-site work may still be valuable for first board bring-up, lab measurements or debugging peripherals that are unavailable to the remote specialist.
Device Tree quality is shown by valid bindings, clean compilation, correct boot logs and reliable peripheral behaviour. Ask the specialist to explain the hardware relationships, test approach and reason for each non-standard property instead of accepting copied descriptions.
Device Tree expertise goes beyond editing nodes until a device appears. A strong professional understands kernel conventions, power and clock dependencies, interrupt routing, schema validation and upstream-friendly design, and communicates clearly with hardware and firmware teams.
