Amir El Arbi

Amir El Arbi is a Tunisian competitive programmer and mathematics/computer-science student. He represented Tunisia at the International Olympiad in Informatics (IOI) 2022 in Yogyakarta, Indonesia, scoring 109.75/600 (rank 220 of 349) and earning an Honourable Mention; he competed again at IOI 2023 (130/600, rank 212). Raised in Sfax, he attended Lycée Pilote de Sfax, then the CPGE MP2I at Lycée du Parc in Lyon, and is now enrolled in Mathematics and Computer Science at ENS Paris-Saclay in France. On Codeforces he competes as a Candidate Master under the handle AmirElarbi, and he has served on Tunisia's national competitive-programming team within the Informatics Tunisian Association (ITA).

Signal

Public footprint is dominated by competitive programming rather than social media: no X/Twitter account is linked, and his visible activity is IOI appearances, a Codeforces Candidate Master profile, and a single 2022 blog post rallying the community to crowdfund Tunisia's on-site IOI trip. The signal is that of a strong student competitor who engages through olympiad/CP channels rather than general social platforms.

• Won an Honourable Mention at IOI 2022 (109.75/600, rank 220/349) representing Tunisia, and returned to IOI 2023 (130/600, rank 212) - only the minority of IOI participants compete twice, marking him as one of Tunisia's stronger recurring contestants.Aug 15, 2022
• In July 2022 he led a public crowdfunding campaign on the local cha9a9a.tn platform, posted on Codeforces as AmirElarbi, to fund the Tunisian team's on-site travel to IOI 2022 - the team otherwise could not afford the Tunisia-Indonesia trip, underscoring funding gaps for Tunisian olympiad competitors.Jul 5, 2022Helping the Tunisian National Team participate in the on-site IOI 2022 - crowdfunding appeal to cover travel from Tunisia to Indonesia; signed 'Amir Elarbi', IOI 2022 team member.
• Academic trajectory Lycee Pilote de Sfax -> CPGE MP2I at Lycee du Parc (Lyon) -> ENS Paris-Saclay Maths & CS places him on France's elite grande-ecole pipeline for math/CS rather than a purely Tunisian university path, which suggests he emigrated for study after high school.
• Competes on Codeforces as Candidate Master under handle AmirElarbi (from Sfax, Tunisia).
• The IOI 2022 Tunisian team was Amine Ouesleti, Amir El Arbi, Hedi Chehaidar and Mohamed Ali Saidane, a small stable cohort that also recurs across Codeforces.Jul 5, 2022
• Held leadership in the Microsoft Tech Club at Lycee Pilote de Sfax as President and Manager of Training, i.e. teaching younger students before university - an early teaching/organising signal alongside his own competition record.
• Listed as a member of Tunisia's Competitive Programming National Team within the Informatics Tunisian Association (ITA), the body that runs Tunisia's olympiad selection.
• Tunisian press (Le Temps, Realites) covered the national IOI 2022 team's qualification, framing olympiad performance as a route to elite universities abroad - the same path that led him to ENS Paris-Saclay.Aug 11, 2022
