Bartosz Wawrzynek

I am an experienced Embedded and IoT Software Engineer with over 8 years of professional experience in the industry. I have worked on designing and delivering reliable software for embedded systems, industrial devices, and IoT products operating in real-world, mission-critical environments.

After many years of hands-on engineering and product development, I founded Asbar Technology to continue growing technically and to provide clients with high-quality, flexible, and future-proof software solutions.

My expertise includes:

• Embedded software development for RTOS (Zephyr, ThreadX, NuttX) and Embedded Linux
• Designing platform-independent and portable applications
• Software architectures resilient to hardware and platform changes
• Secure wireless communication: LoRa, BLE, radio-based systems
• Security-focused designs compliant with Cyber Resilience Act (CRA) requirements
• CI/CD pipelines, unit testing, static and dynamic code analysis
• DSP and signal processing (including FMCW radar algorithms)
• End-to-end device-to-cloud integration (AWS IoT, OTA updates, monitoring, Python backends)

How I work:

• I focus on clean, maintainable, and well-tested code,
• I design systems ready for long-term scaling and product evolution,
• I think beyond code — with a strong product and system engineering mindset,
• I value clear communication, documentation, and real business impact.
