    I chose Maryam to undertake my project because she struck me as a very capable and talented engineer, and she has proven that is true. My correspondence has not been with Maryam directly, and I understand that culturally a woman can't talk to a man, but having a go between has made "attention to detail"...

    I had a really good experience working with him on my hardware project. I originally came in with just an idea, some rough requirements, and a general concept of what I wanted to build, and he helped turn it into a real working prototype step by step. He handled everything from the schematic design and...

    Maryam was great! I needed a PCB for a project and I have 0 experience building small electronics. I gave her a description of what I wanted and was nervous I did not explain well enough due to my little knowledge, but she delivered exactly what I was looking for! She was fast to respond and answered...

    This is the start of a large job that I asked to be made into steps. But it is very clear that even by the rough draft, there is an exceptional level of understanding and passion in the work. I am legitimately excited to see the next steps and the end result! Thank you!!
