Since 2018 I have been a member of the Scientific Committee of the National Informatics Olympiad, having authored or co-authored multiple problems, written various problem statements and prepared the students for international competitions:

Problems authored by me include*:

• Qualifications: 

  • 2020 - Problem B; 

  • 2023 - Problem A (co-authored with Pedro Paredes); 

  • 2023 - Problem C (co-authored with Pedro Paredes); 

  • 2024 - Problem A; 

  • 2024 - Problem D; 

  • 2025 - Problem A;

  • 2025 - Problem D;

  • 2026 - Problem B.

• Finals: 

  • 2023 - Problem C (co-authored with Kevin Pucci); 

  • 2024 - Problem C;

  • 2025 - Problem C; 

  • 2026 - Problem A.

• Selection Tests: 

  • 2021 - Problem D; 

  • 2023 - Problem B; 

  • 2024 - Problem D (co-authored with Alberto Cavaleiro);

  • 2025 - Problem D.

Furthermore, I served as Deputy Leader of the Portuguese Delegation at the International Olympiad in Informatics in 2023, in Hungary.

I was also a Judge in the International Collegiate Programming Contest Southwestern Europe Regional Contest (ICPC SWERC), in both 2024 and 2025. 

*I do not claim all of these problems to be fully original, they were often inspired by other problems from programming or mathematics competitions and I would later find some of them elsewhere, even if I had independently thought of them (for instance, 6 years after having the idea for problem D of the 2021 Selection Test I found out it was the subject of an earlier paper).
