Independent Embedded Software Consultant

Embedded software engineering, built for your hardware.

I'm Lars Brodersen, a freelance embedded software engineer based in Aalborg, Denmark. I help companies design, build and ship reliable firmware — from first prototype to production. I also take on smaller projects and individual tasks within larger projects, including troubleshooting software-to-hardware interface issues, and more.

I work across ARM Cortex-M platforms (including STM32 and Nordic), with protocols such as I2C, SPI, UART, CAN, and BLE, as well as sensor interfacing, battery monitoring/surveillance, RTOS-based systems, and low-power design

Services

What I can help with

Focused, hands-on embedded engineering — from a first prototype or test rig to a production-grade firmware audit.

⚙

Firmware & driver development

C/C++ firmware for microcontrollers and embedded Linux, including low-level drivers, bootloaders and board bring-up.

⏳

RTOS & real-time systems

Design, implementation and debugging of real-time embedded systems where timing, power and reliability matter.

🔍

Code review & technical audits

An experienced, outside perspective on existing firmware — architecture reviews, debugging support, performance audits.

🧪

Prototyping & proof of concept

Fast, pragmatic prototypes that validate a hardware/software concept before you commit to full-scale development.

🔌

Prototype & test hardware

Small, purpose-built hardware with matching firmware and PC tools — test jigs and programming fixtures, sensor evaluation setups, data loggers, interface adapters and simulators for devices that don't exist yet.

📚

Legacy system support

Maintenance and modernization of older embedded and telecom codebases — expertise fewer engineers still carry.
