All of your questions can be answered if you come in paid analysis. Navneet Khanna jee will answer your questions. First you asked your marriage. Later you asked for IT job. Now you are asking to explain mangal dosha, period analysis, Sade sati etc. This forum is meant for answering one question. Please contact Navneet Khanna Jee.
It is better to trust your local astrologer, who said that Mars dosha is minimal. Saturn is conjoined with Moon in 2nd house. It gives you postponements, lethargic life etc.
Without beating the bush, I answered your questions. If that does not happen you ask. It can be answered.
Mars dosha : If Mars is in 2nd (addition to family), 4th house (domestic happiness), 7th (kalatra), 8th (mangalaya) and 12th (bed comfort) from either Moon, Venus or Lagna, it is said as Kuja dosha or Mars dosha. Mars is in 11th bhava from lagna it is good. From Moon it is in 10th sign. From Venus it is in 2nd sign. From Venus it is there. But Mars is in its own sign. It is ineffective. So you need not worry. Keep trust in your local astrologer. If you have any more doubts, please consult him.
Good Luck
