Karol Konaszyński

Karol Konaszyński is a Polish software engineer and competition-math and competitive-programming veteran. He represented Poland at the 2009 International Mathematical Olympiad in Bremen, winning a bronze medal (22 points). He was a two-time finalist of the Polish Olympiad in Informatics (2007/08 and 2008/09) and is associated with the Institute of Mathematics at the University of Wrocław. He later competed at the ACM-ICPC World Finals (2014, with Saarland University) as Codeforces user 'Karoluch' / Topcoder 'karoluch'. He is now a Senior Software Engineer at Google (Account Security).

• Now a Senior Software Engineer at Google on Account Security, based in Switzerland (ch.linkedin.com) - a security-platform role that follows naturally from a competition-math and algorithms background.2025
• Represented Poland at IMO 2009 in Bremen and won a bronze medal with 22 points (rank 168 of the field), the same score as teammates Damian Orlef and Tomasz Pawłowski.Jul 2009
• Competed at the ACM-ICPC 2014 World Finals (rank 94) on team COMEFROM Saar of Saarland University, indicating he moved to Germany for graduate study after Wrocław.Jun 25, 2014
• Was a two-time finalist of the Polish Olympiad in Informatics (2007/08, 2008/09), so he was already a strong competitive programmer before university - the through-line to his later ICPC and industry career.2009
• Studied mathematics at the Institute of Mathematics, University of Wrocław (listed as 'student IM' among the faculty's math-olympiad laureates) - the same institute that produced IMO medalists like Kamil Duszenko.2009
• Competitive-programming identity is unified under the handle 'Karoluch' across Codeforces and Topcoder, with CPHOF listing Germany as his country by the mid-2010s.2014
• His Olympiad strengths split cleanly across the paper: full marks on P2 and P5 but only 1 point on P3 and P4, a profile that suggests geometry/inequalities clicked while the hardest constructions did not.Jul 2009
• No GitHub account or personal blog is discoverable under his name, which is unusual for a Google SWE and suggests he keeps his engineering work inside the company rather than in open source.2025
• Social footprint: Instagram @karolkona and a public Facebook profile (facebook.com/karol.konaszynski); no dedicated personal site or blog surfaces in search.2025
