Posts rarely on X (16 followers), almost entirely about parametric complexity theory - treewidth, W-hierarchy, maximum independent set - and campus life at KAIST (a lecture by Dabeen Lee). The narrow, technical focus and low follower count read as a graduate-track CS student using the account as a personal outlet rather than a professional surface.

• Won a silver medal at IOI 2021 for Bangladesh, ranking 72nd of 351 with a score of 302, his best IOI result after three prior appearances (2018-2020) without a medal - a four-year climb to the podium.Jun 25, 2021
• Public contact email [contact omitted], listed on his IOI statistics profile.
• Serves on the National Scientific Committee of the Bangladesh Olympiad in Informatics (BdOI), the body that runs the national olympiad he once competed in - a move from contestant to organizer.
• Research intern at the Huawei Hong Kong Research Center (HKRC), pointing his interests toward research beyond contest programming.
• Competed at IOI in 2018 (rank 170), 2019 (rank 212), 2020 (rank 212) and 2021 (silver) - a rare four-time Bangladeshi IOI contestant, which anchors him early in Bangladesh's competitive-programming scene.
• Uses the Codeforces handles 'memento' and 'TheeLooser'; the latter appears in his X bio, tying his CP identity across platforms.
• Teaching Assistant for CS.30202 Formal Languages and Automata at KAIST, indicating graduate-level coursework strength in theory.
• Worked as a problem setter for CodeChef, converting his contest skill into setting problems for a global platform.
• Co-author of 'Dynamic Programming Book', a DP textbook in Bangla (hosted at dp-bn.github.io) - an effort to make CP theory accessible to Bangla-speaking students.
• Studied at Chittagong College before KAIST; LinkedIn lists a Bachelor's in Mathematics and Computer Science at KAIST.
• Maintains a competitive-programming blog at mamnoonsiam.github.io with posts on segment trees, shortest paths and interactive problems, plus unfinished notes on interactive/communication tasks.Jan 1, 2022
• Recorded BdOI preliminary contest analysis and intro-to-DP lecture videos under 'CP at CJC' (Chittagong College), suggesting he mentors Bangladeshi students.
