This revolutionary Class II medical device, FDA-approved under K233077, was developed by a multinational team of 10 engineers and medical advisors under my leadership.
The device employs a groundbreaking approach to chronic wound treatment, combining non-coherent light therapy with advanced camera systems to assist operators and ensure patient safety.
This complex system integrates multiple custom and OTS PCBs, supports a variety of communication protocols and programming languages, and features an intuitive user interface designed for seamless operation. Led it from the start to the production.
Developed under tight financial and supplier constraints, this mechanical insufflation-exsufflation device (commonly known as a cough assist) outperforms competitors like the Philips Philips E70/T70.
Optimized to its core, just as an example, the device runs its GUI, control and sensing loops, machine states, and other critical functions on a simple 8-bit microcontroller.
This was the first approved medical device where I had a critical impact—a project that marked the beginning of my journey, taught me invaluable lessons, and still inspires ideas for improvement. I am feeling nostalgic now...
This portable medical device enhances physicians' diagnostic capabilities by extracting key wound parameters invisible to the naked eye. It achieves this through a combination of specialized cameras, light sources, sensors, and AI.
Integrated with an online platform, it has the potential to revolutionize the wound-assessment market, benefiting countless patients.
Developing this device introduced new challenges, including design for manufacturability (DfM) for high production volumes, image processing and refinement, and the development of AI features tailored to medical applications.
Currently under development and strict IP protection, this project has introduced me to the unique challenges of endoscopes. These include image processing and comparison techniques, specialized insulation requirements, and other specific needs of this class of devices.
Developed and certified during the critical days of the COVID pandemic, this mechanical ventilator was designed for Brazilian patients not fully dependent on mechanical ventilation for survival.
Its development faced huge challenges, including shortages of raw materials, electronic components, and specialized workforce. To overcome these hurdles, our team partnered with Whirlpool engineers, finding innovative solutions.
These hard times provided valuable lessons and strengthened my ability to adapt and deliver under extreme conditions.
Prior to the development of this device, the Brazilian veterinary market faced a significant gap: the lack of a cost-effective, purpose-built solution tailored specifically for veterinarians that needed a portable anesthesia and ventilatory device.
This project introduced me to new areas such as customer-centric design, user interviews, field performance evaluations (that’s me in the picture), and direct collaboration with the client.
The result was a functional, user-friendly device that remains affordable for the majority of veterinarians, addressing a critical need in the market.
Managing the certification process, including documentation and hardware testing, for medical devices developed by third parties (often Chinese companies) entering new markets.
Development and implementation of hardware, firmware, and software of a 27 degrees of freedom (DoF) Inertial Measurement Unit (IMU) based on Madgwick and Kalman Filters.

Designing consumer-grade PCBs focused on scalability, wide operational temperature ranges, and diverse usage patterns.
For example, the Buck converter shown in the image was engineered to connect to an external battery and regulate the output voltage from 4.5V to 12V, delivering up to 30A with a maximum temperature rise of 28°C, all while meeting EMC requirements.
To reduce the discomfort of traditional polysomnography and complete my graduation, I developed a battery-powered sleep analysis system. This was my first PCB project, consisting of three boards designed to monitor various aspects of sleep.

Designed the analog front-end, signal processing, and data storage for a portable electrocardiograph interfacing with iOS and Android devices via Bluetooth 2.0. The project focused on cost-effectiveness for the Brazilian market while adhering to Apple's stringent documentation requirements. The result was a functional prototype that was able to communicate with iPhones and had a pretty decent SNR.
