You need hardware that doesn't just work—it needs to be reliable, power-efficient, and secure. I help startups and product teams turn complex hardware concepts into production-ready firmware. Whether you are building an IoT sensor network, a secure access system, or an autonomous monitor, I bridge the gap between abstract requirements and stable, real-time code. Why work with me? 1. Production-Ready Mindset: I don’t just write code; I design for reliability, power optimization, and scalability. 2. Full-Stack Embedded: Proficient across ARM platforms (Nordic nRF, STM32) and RTOS environments (Zephyr, FreeRTOS). 3. Proven Track Record: From Autonomous Structural Health Monitoring (BLE Mesh) to NFC-based access control, I have navigated the challenges of custom driver development and real-time sensor integration. My Core Capabilities: 1. IoT Connectivity: BLE Mesh, NFC security, and multi-hop communication networks. 2. Firmware Development: STM32/nRF firmware, custom sensor drivers, and peripheral integration (I2C, SPI, UART). 3. RTOS & Power Optimization: Managing task scheduling in Zephyr/FreeRTOS and designing LPN (Low Power Node) logic for battery-operated devices. Your hardware project doesn't have to be a headache. Let's discuss your requirements—send me a message, and let's see how we can get your prototype or product on the right track.
