in the United States

I’m a Professional Engineer of California in Electronics, Communications, and Controls, experienced in RF, embedded systems, and automated test development for hardware-focused teams. I am educated on the West Coast in Electrical Engineering with an emphasis on wireless technologies and am working toward a Graduate degree in Signal and Image Processing. Whether you need help with prototyping, validation, troubleshooting, or building reliable engineering workflows, I can help. - Experience with RF systems, embedded hardware, Python tools, and lab/test automation - Loves to work on long-lasting custom wearable tech! - Support from concept development through integration, validation, and production handoff - Strong communication, documentation, and cross-functional collaboration

Professional Summary: Electrical Engineer experienced in developing electronic products for medical, industrial and aerospace/defense programs. Responsibilities include application of electrical hardware experience, analog / digital circuit design including simulation, validation, project management, efficient documentation including new product cost and excellent oral / written communication skills.

With more than 15 years of experience developing electronic devices, I have been leading R&D and manufacturing teams using innovative approaches to design, test, assembly and validateinnovative products. I am an experienced electrical engineer with experience developing innovative products integrating technoligies, such as RFIDs, Battery Management Systems, Robots, Drones and IoT devices. I provide my customers with the engineering packages to be transfered to manufacturing. I develop and guarantee my customers the suppy chain for their products. I have a fully equipped laboratory to design, prototype and validate the systems. I have also access to capabilities for microfabrication (cleanroom facility) for the development of sensors and integrated circuits.
