I didn't consider reverse engineering. But still I doubt they have produced anything noteworthy. They said they reserve engineered or engineered so many things and all of them failed or they show some shady photoshop pictures. For example that Gaher Iranian fighter or American stealth UAV. Most experts say those things can never fly. They are made of wood from the inside. Maybe this time they managed to do something and that air system can really fire but I wouldn't be surprised if those barrels are empty.
The difference between real military industrial countries and Iran is this. Iran says they produce something and let the whole world know by big billboards with big text behind mishmash products while the latter doesn't feel the need to do this. I mean we still haven't seen one Iranian product that worked. They simply don't have the trackrecord. They have been lying and manipulating so what is different this time? If somebody is lying for years he can be right once but I rather not believe him anyways since a liar doesn't change overnight.
LOL, not even one!!!
Here I just post some AD assets videos for you to see:

I disagree that Iran is advanced on all fields. Pakistan has nuclear power and Iran doesn't. If they want they can nuke Iran to oblivion. The only think Iran produced was UAV but they are almost on the same tech level as the toy RC planes you can buy in toy stores. You shouldn't blame Pakistani or other people that people look at Iran's public anouncements with skeptic eye. They have been trying to fool their own people the most and also neighboring countries with things they failed to develop. Instead of putting all that energy in photoshop, vegas pro and doubleganger monkeys they should produce actual products.
