    I would definitely recommend Alex to anyone and work with him again in the future. He was professional and friendly, accommodated my wishes and changes, and demonstrated great expertise—he really knows his stuff and offered good counter-suggestions.

    Alex has amazing attention to detail and an exceptional understanding of electronics and PCB design. I have had a terrible experience with a previous freelancer who failed to meet my PCB specifications and I needed someone new to help me finish the job correctly. Alex was the perfect choice. I will definitely order again soon.
