Saeed Al Tunaiji has extensive experience in managing projects and initiatives related to the book and publishing industry, as well as cultural and literary events. He has led many pioneering projects since 2003 that serve Abu Dhabi's ambition to achieve leadership of the Arabic language in the cultural, creative, and educational fields, and aim to strengthen Abu Dhabi's cultural position at the local, regional, and global levels under the umbrella of the Department of Culture and Tourism - Abu Dhabi, including the Sheikh Zayed Book Award, the Kalima Project for Translation, the Esdarat Publications Project, the Abu Dhabi International Book Fair, as well as Al Ain and Al Dhafra Book Festivals.

Al Tunaiji assumed his duties of executive management of the Abu Dhabi Arabic Language Centre in 2022 with the aim of supporting the centre's strategic programmes, directing the centre’s work within those programmes’ strategic framework, and achieving the centre’s goals. The centre has been able to accomplish many achievements under his leadership, most notably doubling the number of visitors at the 2022 Abu Dhabi International Book Fair compared to previous editions, and the presentation of the Al Ain and Al Dhafra Book Festivals in a revamped look and presence that helped drive a literary and cultural movement by registering a 50% increase in the number of visitors to both events. He also helped launch the first edition of the Kanz Al Jeel (Treasured Sayings) Award that supports the rich Nabatean poetry heritage.

Al Tunaiji moved up the administrative ladder and gained excellent expertise. He started his career as a journalist, working in several Emirati newspapers and held many positions at the Department of Culture and Tourism - Abu Dhabi, the most important of which was the Director of Media and Public Relations. He has published several books including "From and to the Depths of the Nation", "Mosaic", "Her Majesty’s Mistakes", "Inspired by Emirati Poetry", and "Immortal Despite Being Absent".
