Kassem held several positions away from the field of literature, working in the Information Department of the UNESCO National Division from 1975 until 1977, then at the Institute of Commercial Art of the Technological College of Alexandria as Head of the Library Department from 1977 until 1984, and at the Egypt Foreign Trade Company of Alexandria from 1984 until 1985.

He used his scientific studies to present stories about science in a simplified manner, and to gather knowledge to create encyclopedias for the development of peoples. He published about ten novels in the past, 20 books on Egyptian cinema, and more than 10,000 articles in Arabic newspapers and magazines. he began writing articles in 1980 for the Evening Journal, and then for the Kuwaiti Arabic Magazine. Despite the publication of 25 encyclopedias, Al-Kassem refused to be named by anyone as the writer of the encyclopedia because he had done nothing but plant the first seed: gather information, give responsibility to cultural institutions to take over the rest of the process, and avoid discussing his work at seminars and cultural gatherings.

In addition, Al- Kassem translated 12 works into French, including four issues by the Egyptian-French writer, Albert Qasiri. He also produced television and radio series for adults and young people, including "Adventures of Gilgel and Pepper," which were shown on Egyptian and Arabic radio channels. The author of the film "Terrorism and the Kebab," "A Deposed Lawyer," and "Tell Yashahr Zad," was critical of the work of the senior Senarist, Wahid Hamid, and even admired for writing about the relationship of the weak citizen with powerful authorities and his use of rebellion and protest to combat his current situation.
