Mateusz L.

I'm professional electrical engineer specializing in development of embedded systems with strong focus on ARM family of micro-controllers. In embedded world I'm equivalent of full stack developer. I can formulate project technical specification, design PCBs, develop and deploy firmware and prepare manufacturing process. My strong points are wireless communication technologies (especially Bluetooth LE) and embedded cryptography solutions. I have also worked with Sigfox, LORA, NB-IOT and LTE-M devices and have working knowledge of certification and design requirements. I'm also experienced in low power devices (multiple years of life on single charge). As for relevant experience I've designed, built and developed hardware and firmware for modular IoT development kit 'Smablo' ([login to view URL]). The heart is Nordic nRF52 Bluetooth LE MCU supplemented with over 30 sensors/actuators with the complete set of drivers in form of SDK. All Smablo components were mass produced based on my design and assembly documentation. During this project I've also worked on a projects for a few notable companies like Intel, Samsung Poland, Orange Poland and others. We've provided a complete package designing product from an idea to fully working device ready for market. Recently I've designed debugged and implemented real time electric grid monitoring system based on Intel Apollo Lake platform for one of the biggest Nordic electric companies. This amounted to designing whole PC motherboard, custom set of sensor interfaces, uninterruptible power supply with battery management, custom PC BIOS and measurement firmware. I was also responsible for complete manufacturing and assembly documentation.
