Noor was pleasant to work with, but the final quality of the deliverable wasn't quite production-ready. To be completely fair, she did try to correct errors after final delivery, but after about 4 attempts, I figured it was time to let go. The final result still had USB-footprint hole-clearance DRC errors,...

I have made several revisions (as separate orders) together with this developer, as I tested and updated my requirements for my board. What I can say is that they are committed to delivering a product you are satisfied with, are open to feedback, quick to respond, provided aid in adjusting for parts...

Noor did an excellent job updating the firmware for our custom fan-control PCB. She understood the hardware requirements, clearly explained the control strategy, and responded quickly to questions and requested changes. She was professional, knowledgeable, and easy to work with throughout the project....

Can't say I would order again unfortunately. I was provided a board with a short circuit in it that I had previously pointed out and was told it was removed but was again in my final delivery. The design also had a very large component in the design that did not fit on the component foot print, which...

You need to have the same level of technical knowledge as the freelancer to be able to continuously identify and correct the errors. Several mistakes were repeated multiple times, and in the end I had to correct them myself. At first, I thought the problem was related to the compensation, so I even...
