Hire the Best Arduino Experts
in Argentina

👋 About Me I'm an Electronics Engineer, with strong expertise in hardware design, control systems, and medical device development. I bring over 3 years of hands-on experience taking projects from concept to production — including system architecture, schematic design, PCB layout (rigid and flex), prototyping, testing, and manufacturing support. I currently lead the hardware development at CHLAB, a consulting firm dedicated to custom electronics. My daily work involves designing complex circuits, selecting components, building and debugging prototypes, and validating systems in a fully equipped electronics lab. Some highlights from recent projects: 🩺 Non-invasive arterial monitoring system: Designed and built the entire hardware for a wearable device that extracts markers like arterial stiffness and pulse wave velocity. Worked closely with doctors and researchers to test the system on real patients. 💡 Sphere-shaped LED product: Integrated 600 addressable LEDs on a flexible PCB inside a tennis ball–sized enclosure, with onboard battery and control electronics. ⚙️ High-power LED drivers: Developed constant-current and PWM dimmers up to 100 W, including thermal design and EMC compliance for mass production. I thrive in multidisciplinary teams where engineering meets real-world impact — especially in wearable health devices, sensor systems, and smart embedded hardware. I'm proficient with tools like Altium Designer, KiCad, Eagle, SolidWorks, and MATLAB/Simulink, and I regularly work with STM32 and ESP32 platforms for embedded development. Whether you're prototyping a new idea or refining a design for production, I can help you move fast with reliable, high-quality hardware.
