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,...

Noor was very helpful in creating my PCB. I did have to make some changes midway through and the lead time was a little longer than I’d hoped but it was understandable given the amount of detail I gave her. She was very responsive when I had issues and made the necessary changes.

It was quite a good 1st project. For sure I will come back for more work. The part I need to learn is that I expect the freelancers do what I ask them to where the freelancers think they need to do more (check my question) where it's not needed, except when I explicitly ask for it.

Provided detailed files and helped me understand the circuit board since I am a beginner. Went above and beyond in helping me order and answer any questions I had. I will definitely come back for the next board revision and will stay in touch long term. Thank you again.

This is my second time working with Noor. She was able to make modifications to the PCB based on mechanical design changes. She was patient and delivered high quality layout and SMT files.
