I specialize in developing robust and scalable firmware architectures, built to the highest professional standards. My background as an electronics engineer with a deep understanding of both digital and analog hardware allows me to tackle complex technical challenges with confidence and efficiency. Notably, three devices featuring firmware I personally developed were showcased at CES 2018, CES 2019, and CES 2022 — a testament to the reliability and real-world impact of my work. My expertise and skills include: - Platforms: nRF52x, nRF53x, nRF9160, EFM8, EFM32, CC26x2 - Languages: C, C++, C++Builder, Delphi, Assembler MCS-51 - Tools, IDE: Visual Studio Code, Keil, Segger Embedded Studio, IAR, STM32CubeIDE, RAD Studio, etc. - Technologies, libraries: nRF Connect for VS Code, nRF5 SDK - RTOS: Zephyr, FreeRTOS, TIRTOS - FOTA (Firmware Over The Air): Nordic nRF52 - BT/BLE: u-blox Nina-B1, Holyiot 18010, Nordic nRF52x, SimCom SIM868, Texas Instruments CC2642/CC2652 - GNSS: u-blox SAM-M8Q, TranSystem EB-240, Trimble, Rockwell, etc. - Long range communication: GSM (GPRS/CSD/SMS), 3G/4G LTE (u-blox SARA-R4, SimCom SIM800/868/900, Siemens, Telit, etc.) - Short range communication: ISM (434 MHz, 868 MHz, 2.5 GHz), Bluetooth, NFC - Digital interfaces: USB, RS-232, RS-485, UART, SMB, SPI, I2C, 1-Wire, etc. - Source control: Bitbucket, Sourcetree, GitHub I bring a pragmatic, results-oriented approach to firmware engineering — always focused on reliability and performance.

I help companies transform embedded product ideas into reliable, production-ready devices. I'm a Principal Embedded Software Engineer with 20+ years of experience developing commercial embedded systems from concept through manufacturing. I work across the entire product lifecycle—from system architecture and firmware development to hardware bring-up, production testing, and manufacturing support. My background combines deep low-level firmware expertise with practical product development. Earlier in my career, I spent more than 10 years developing RTOS components, networking stacks, USB stacks, bootloaders, device drivers, and low-level embedded software. This foundation allows me to quickly understand complex systems, identify root causes, and design robust solutions. I don't just write firmware—I help build complete embedded products.
