In 2025, due to professional dissatisfaction and payment-related complications, he announced his retirement from professional screenwriting. However, in 2026, he jointly won the National Film Award for Best Story with Raihan Rafi for the film Surongo. Currently, he is focused on writing literature.
Nazim Ud Daula completed his Bachelor of Business Administration (BBA) and Master of Business Administration (MBA) in Marketing from the University of Dhaka. After finishing his education, he briefly taught as a lecturer at a private university in 2016. However, lacking interest in teaching, he later joined the corporate sector and engaged in creative work.
Nazim Ud Daula has been practicing writing since his teenage years. Initially, he wrote on various blog sites and Facebook. In 2012, his first story, 'Kobi' (Poet), was published in the 'Kalantor Sahitya Samayiki' (Kalantor Literary Magazine). While studying at the University of Dhaka, his first thriller novel, Incarnation, was published at the 2015 Ekushey Book Fair. In August of the same year, his second novel, a historical thriller titled Bloodstone, was published. These two books brought him immense popularity among readers during his student life. By 2019, he had published five books. His notable literary works include Mohajatra, Mithya Tumi Dosh Pipra, Scarlet, Bridge Rokkhok, Sotyer Moto Bodmash, and the Detective Mansur series books Prohelika, Kuhelika, and Jobonika.
After completing his studies, he briefly worked as a lecturer at a private university. However, driven by his interest in creative work, he left teaching and entered the advertising industry. From 2017 to 2018, he served as a Project Manager at an agency named 'Geeky Social'. He subsequently joined the digital marketing agency 'Analyzen Bangladesh Limited', where he worked for four years. In November 2022, he resigned from his position as 'Creative Supervisor' at Analyzen. During his time there, he used the pseudonym 'Masud Rana'. Later, he also worked as a Creative Manager at the production company 'Alpha-i'. Working in advertising agencies for a long time helped him acquire the technical skills of storytelling and screenwriting.
In 2018, after reading his book Mohajatra, Abdul Aziz, the head of Jaaz Multimedia, found the vibe of 'Masud Rana' in his writing style. Consequently, he offered Nazim to write the screenplay for the film ' (2023). This was his first project as a screenwriter. To prepare, he completed a two-month virtual screenwriting course from an institution in Hollywood. He prepared about 16 drafts of the film's screenplay and showed them to the original author, Qazi Anwar Hussain, who highly praised the script. However, Nazim noted that due to technical complications and foreign locations, the film's shooting could not fully follow his original screenplay.
Although his career began with a film screenwriting offer, his formal journey started through the small screen. In 2018, Vicky Zahed directed the short film Aaj Amar Pala based on his story. He also wrote the screenplay for Vicky Zahed's drama Lovers Food Van. In 2021, Nazim wrote the screenplays for two fiction episodes, Akash Bhora Tara and Ek Bhai Champa, from the 'Shortcut' series directed by Shafayet Mansoor Rana for the OTT platform Bioscope. He also worked on Sanjay Samaddar's web fiction Lohar Tori. His other notable web contents include The Dark Side of Dhaka, Khachar Bhitor Ochin Pakhi, Buker Moddhye Agun, Shuklopokkho, and The Silence.
His feature film debut was the 2022 film Shaan, directed by M. Raahim. This was his first screenplay to be released on the big screen. Following this, he wrote the screenplays for Dipankar Dipon's Operation Sundarbans (2022) and Raihan Rafi's Damal (2022). Regarding Damal, he mentioned that due to technical limitations, his screenplay could not be entirely translated onto the screen.
Nazim Ud Daula's screenwriting philosophy involves blending commercial and artistic elements in films. Even when considering the Censor Board, controversial topics, or the political situation, he generally structures the story in his own way first and later modifies it according to the director's and producer's demands. He has frequently collaborated with directors like Raihan Rafi, Sunny Sanwar, and Dipankar Dipon. He claims that about 95 percent of his screenplay was faithfully portrayed on screen in Raihan Rafi's Surongo (2023). During the scripting of Surongo, he regularly visited the shooting spot and instantly planned and wrote the scenes inside the tunnel while sitting on the set. He even injured his leg once during the filming of this movie.
His final works as a professional screenwriter include Insaaf (2025) and NeelChokro (2025).
On 18 September 2025, Nazim Ud Daula announced on social media that he would no longer work as a professional screenwriter. He alleged that the Bangladeshi entertainment industry does not give writers the respect, credit, and proper remuneration they deserve. Out of frustration over unpaid dues and lack of proper evaluation of his work, he expressed regret over turning from a "creative writer" into a "commissioned writer".
Currently, he is focusing entirely on writing original literature. Even after receiving the National Film Award in 2026, he told the media that he would not return to professional screenwriting.
Nazim Ud Daula is married and has one child. After taking a break from writing for the screen, he is currently running his own startup business.
