• Quant employment verification: CONFIRMED. LinkedIn profile enrichment (index/provider-sourced, not independent primary confirmation) lists Wojciech Śmietanka, United Kingdom, as a Quantitative Developer at Quadrature beginning 2017-08; Quadrature (quadrature.ai / Quadrature Capital, London) is a systematic/quantitative trading firm, so this is an actual quantitative-finance role rather than a name-only 'quant' match. Identity is supported by the exact name 'Wojciech Śmietanka', a Polish background consistent with the IMO 2005/2006 Poland representative, and a quantitative/software profile. Caveat: the employment evidence rests on the index/LinkedIn profile and was not corroborated by an independent primary source in this run; a secondary 'Software Engineer at G.' entry in the same index is internally inconsistent and was not treated as a confirmed employer.
• LinkedIn lists the role 'Quantitative Developer' at Quadrature with a start of 2017-08; this is index/provider-sourced (self-reported profile data), not independent primary-source confirmation.
• Quadrature (quadrature.ai / Quadrature Capital) is a London-based systematic/quantitative trading firm, so the indexed Quantitative Developer role is a genuine quantitative-finance employer rather than a name-only 'quant' match.
• Represented Poland at IMO 2005 (bronze medal, 15 pts, rank 207) and IMO 2006 (silver medal, 21 pts, rank 98).
• Won a gold medal and 2nd place at the ICPC World Finals 2012 for the University of Warsaw, one of the strongest competitive-programming results on record.
• Enrichment also lists a second current role 'Software Engineer at G.' with an implausible date range (2012- ), which is inconsistent with a 2017-08 Quadrature start and is treated as unreliable index data rather than a confirmed concurrent employer.
• Competes under the handle 'kefir' on Codeforces and TopCoder; TopCoder Open Algorithm 2010 top-24 and Google Code Jam 2010 final qualifier (per competitive-programming Hall of Fame profile).
• Member of the University of Warsaw team 'Warsaw Forfiters' (with Tomasz Kulczyński and Jakub Pachocki) that placed 3rd in the Open division of IPSC 2012.
• MIMUW (University of Warsaw Faculty of Mathematics, Informatics and Mechanics) records list team placements for his teams including 2nd place at the 2012 Academic World Championship in Team Programming, consistent with his ICPC World Finals result.
• His competitive-programming circle overlaps with Jakub Pachocki (OpenAI chief scientist), a University of Warsaw contemporary teammate at IPSC 2012, indicating a strong Warsaw CS cohort.
