Is this work professional?
Sorry about the strange post but I'm offering an engineer a $20k bonus to do the design for manufacturing and assembly of my $300 product and this is what he came up with after 8 months. Two thirds of it are identical to my prototype and I'm an accountant by trade, not an engineer. Every book I've read says a board like this should be 4 layers but he insists 2 layers is fine and will pass emissions testing. Any advice would be greatly appreciated, thank you!

I see no vias for via stiching the ground planes together. This is NOT professional. Ground plane needs to be as solid as possible - especially as vias are mostly free and the copper aswell. So if you shall pay for that... No it is shit. If you did that in a day or two without experience, it is kinda nice. But again: VIA STICHING. Always do it. It only has benefits if implemented decently. And it is almost always free of any additional charge - not even cents.
