• Quant employment verification: CONFIRMED. Miliauskas worked as Core Engineer at XTX Markets, Jan 2016 - Feb 2018 (London area), per his LinkedIn profile text (search snippet) and corroborated by Crunchbase ('previously worked at XTX Markets as a core engineer') and Wellfound ('XTX Markets, Core Engineer, 2 years'). XTX Markets self-describes as 'a leading algorithmic trading firm' producing price forecasts across 53,000+ instruments - a genuine algorithmic/quantitative market maker.
