Yep, he's the man for figs but he will need to know your location and type of fig - photos would be very helpful. Photos of the fig tree, the leaves and a wide shot of the area where the fig tree is growing.
This time of year many fig trees get brown leaves from a fungus. Some fungus can be caused by high humidity or too much rainfall. Sometimes low fig fruit production can be caused by too little water or irregular watering schedule. (That's all the knowledge I have.)
