A non-standard transliteration; the five-syllable shape is rare and probably matches an East European or compound surname. Each piece is a stock transliteration syllable:
克 (kè, common for 'kr-'),
瑞 (ruì, 'auspicious' but here phonetic for '-e-'),
斯 (sī, '-s-'),
迪 (dí, '-di-'),
克 (kè, again for the closing '-k').
