Harbour.Space takes over SWERC by winning gold and silver for the first time in its history and will go to the ICPC World Finals. Congratulations to all of our participants and coaches that made this a reality!

This is a very important moment in Harbour.Space and Codeforces long partnership, with 127 educational rounds being organized and a big Harbour.Space Scholarship Contest held on July 22th. We have selected contest winners (early-morning-dreams, Meijer and amanbol) to form our current teams.

Since its creation, one of Harbour.Spaces’s goals has been to win SWERC and compete at a high level in the ICPC globally. On April 24th, that objective was accomplished when Harbour.Space’s team RAW POTS (read it backwards!) won the gold medal and the overall contest against Southwestern Europe’s top contenders.

Harbour.Space

Team Raw Pots — gold medal:

Maksym Oboznyi (MaksymOboznyi), Marco Meijer (Meijer), and Danil Zashikhin (early-morning-dreams)

Team Kempirqosaq — silver medal:

Temirlan Baibolov (bthero), Dinmukhamed Tursynbay (DimmyT), and Amanbol Kanatuly (amanbol), ranked 4th and won a silver medal.

Team Harbour.Backspace — ranked 27th:

Anier Velasco (aniervs), Fadi Younes, and Ekaterina Podruzhko, ranked 27th.

The faculty, current students, alumni, and everyone involved with Harbour.Space would like to congratulate the winners and participants at SWERC 2021-2022 for their wonderful performance and hard work.

As usual, we are always excited to see Codeforces participants as our students here at Harbour.Space. That’s why we encourage you to apply to our latest apprenticeship program in partnership with Hansgrohe, as a Kotlin Developer until May 31st, 2022.
