Development & IT Consultation with Muhammad A.

4.9 · 111 reviews

I'm a PhD scholar in RF & Microwave antennas arrays with seven years of professional experience and a stronghold in research with several publications.
I'm an expert in different software's including CST Studio Suite 3D EM simulation, Advanced Design System (ADS), High Frequency Structure Simulation (HFSS), AWR Microwave Office, and MATLAB.
I offer assistance and consulting in a variety of areas, including concept formulation and design, prototyping, testing, measuring, and troubleshooting. I have complete access to a standard anechoic chamber fully equipped with network analyzers, EMI test equipment, PCB assembly tools, and so on.
For the last couple of years, I have been involved in a research project related to modern communication technologies, designing, prototyping, and testing RF and microwave communication circuits and antennas.
Aside from that, I help and support with the writing of reports, extended essays, dissertations, thesis, and scientific publications, from developing the proposal and working hypothesis (research outline) to proofreading and editing.

    RF Remote Modeling and RF performance recommendations Dr. Muhammad is capable at RF modeling and likely a very good engineer. Communication was disappointing on this project, however. We had a meeting to review the project and requirements and outcomes. We were modeling a 433MHz RF module and antenna to place into our product and talked about this extensively, including the fact that the manufacturer of the module would not provide the design files for the module or the antenna. I shared datasheets and step files of the module and antenna however. Muhammad said that this would not be a problem. Once we began the contract Muhammad began modeling the antenna on an ESP32 2.4Ghz module antenna, which we had never talked about. Once Muhammad provided modeling feedback on the 2.4GHz antenna (which he was told to ignore), he said that he could not model the 433MHz module since he did not have design files. Perhaps I was not clear enough, but I don't know how I could have been more clear. This was all very disappointing but likely a simple misunderstanding. Perhaps if I had the module design files I would consider working with Muhammad again, but I would be concerned about continual miscommunication.

    Part 1 (topology review): Good communication that made it easy to look into the developing stages of the contract. I will hire him again in the future.
