Really enjoyed working with Alfredo. He is very knowledgeable of hardware and PCB boards, LED strips etc. but also a good understanding of software. When things got tough he did not quite, he worked with me to get through it and finish what we started. I will be using his services again very soon.

Circuit simulation for neurostimulator

Fantastic! Al made suggestions that I didn’t even know I needed, and provided a schematic and simulation that exceeded my expectations. Very knowledgable about electronics design and manufacture.
