Featured Projects
IoT Soil Sensor
Client: AgriSense GmbH
Developed firmware for a low-power agricultural sensor node. Implemented a custom driver for a moisture sensor and integrated a LoRaWAN stack for long-range communication, focusing on minimizing power consumption for a 5-year battery life.
ECU Bootloader Optimization
Client: Ziegler Automotive
Refactored and optimized the bootloader for an automotive Engine Control Unit (ECU). Reduced boot time by 40% using hand-tuned Assembly for critical startup routines and improved the reliability of the CAN bus firmware update process.
Real-Time ECG Monitor
Client: MedTec Instruments
Built the complete data acquisition firmware for a portable medical-grade ECG device. Utilized FreeRTOS for task management and implemented a high-speed SPI driver for the ADC, ensuring deterministic, low-latency data sampling for accurate diagnostics.
About r64
r64 is founded on a passion for elegant and efficient engineering. In the world of embedded systems, every byte and every clock cycle counts. My approach is to write clean, maintainable, and highly optimized code that is tailored to the unique constraints of your hardware. With a deep understanding of the metal, I bridge the gap between hardware capabilities and software requirements, delivering solutions that are both powerful and reliable.
