Wael Ajam was born in Hila in 1978, and received his Bachelor's degree in architecture at the University of Technology in Baghdad in 2001. He studied façade design and construction and received a Master's of Enginnering at Hochschule Ostwestfalen- Lippe University of Applied Science, Germany.
After the Iraq War of 2003, a wide reconstruction movement was necessary across the country. Modern building materials and techniques were utilized to rebuild some old Islamic sites. Within that wave, Wael Ajam and his architect partner Shubber Falah have been involved in the restoration of several historic Islamic monuments. The first historic work was the old mosque of Safi-Safa in Najaf, next to Imam Ali’s shrine. They were commissioned to set out the design in 2008 by the Architectural Designer for Engineering Consultancy (known as ADEC) office, which was redeveloping the master plan of the Old Town of Najaf. In 2009, the design of the perimeter wall of Salman Al-Farsi’s tomb to the South of Baghdad were assigned to Shubber & Wael. In 2010, the design of Kumayl's Shrine and Mosque in Najaf was also assigned to them. In 2010, Shubber & Wael signed a contract to design a massive expansion for Al-Sahlah Mosque, opened in 2014. While the design of the expansion was ongoing, the administration of Al-Sahlah Mosque asked the designers to review the new design of the Al-Sahlah historic Mosque, which was under construction at the time.
