    Excellent work and delivered all the parts of the project I requested. The team also gave me the special attention I asked for, since I was not well-versed in setting up the new environments. They took the extra time to guide me through the setup. Thanks.

    Literally he gave me a ppt block with three blocks, no any information, no any calculations, no justification of nothing. I also shared with him my code and pcb design for receiving back nothing. VERY POOR EXPERIENCE. NOT RECOMMENDED.
