About

Building next-generation wearable cardiac monitoring systems at ARETEUS. As Executive Director at ARETEUS, I lead operations and strategic execution for a wearable cardiac platform focused on continuous, multimodal physiological monitoring. At ARETEUS, we are developing scalable biosensing systems integrating ECG, motion, respiration, and SpO₂, powered by ultra-low-power edge AI architectures. My role centers on translating advanced engineering innovation into structured execution across R&D, product development, team coordination, manufacturing support, and cross-functional alignment. With a background in broadcast media and large-scale production environments, I bring experience in high-pressure operations, global coordination, and systems-level execution — now applied to building medical technology platforms. Currently focused on: • Operational scaling of wearable medical hardware development • Supporting R&D and engineering execution • Building cross-functional teams across Mexico and international partners • Advancing noninvasive cardiac monitoring technologies ARETEUS operates as a U.S. company with R&D in Mexico, enabling efficient prototyping and vertically integrated development. Open to collaboration in medtech operations, manufacturing, and strategic partnerships.
