• Quant employment verification: CONFIRMED. Hudson River Trading (hudsonrivertrading.com) is a quantitative/algorithmic trading firm - its own About page states 'We research and develop automated trading algorithms using advanced mathematical techniques', and its founders were Harvard/MIT CS and math graduates - so the employer qualifies as quantitative finance, not merely a name containing 'quant'. The role is a current full-time Software Engineer position per the LinkedIn enrichment index, alongside a continuous seven-year Google engineering career and the absence of the HRT role from any student-program framing. Identity is supported by the personal site (basnieuwenhuizen.nl) cross-linking the same LinkedIn/GitHub/Twitter accounts that carry the Google and RADV history, and by his own About page confirming the Google SRE identity. Caveat: the HRT role is carried by the LinkedIn enrichment index and the LinkedIn public directory, which are index/aggregator sources rather than independent primary-source confirmation; no HRT-run page independently naming him was located.
• LinkedIn enrichment (local index, not an independent primary source) lists current role as Software Engineer at Hudson River Trading in London starting 2026, after seven years as a Google Site Reliability Engineer in Zurich (2016-2026) and a 2011 stint at Moog.
• Also competed at Google Code Jam 2013 (rank 20, $100 prize) and reached the ACM-ICPC World Finals twice: 2013 with Universiteit Leiden team 'Geen Syntax' (rank 63) and 2016 with Radboud University team 'That empty teamname' (rank 53, $1050) - an unexplained shift from Leiden to Radboud between 2013 and 2016 that is not captured in his LinkedIn education history.
• LinkedIn enrichment (local index, not an independent primary source) lists his current role as Software Engineer at Hudson River Trading in London, UK starting 2026, after seven years as a Google Site Reliability Engineer in Zurich (Site Reliability Engineer 2016-2020, Senior SRE 2020-2023 on user-generated-content storage systems, Senior SRE 2023-2026 on Vertex AI model serving), and a 2011 'Aankomend software engineer' role at Moog.
• Self-described in his site's About page: 'For my day job I am an SRE at Google Switzerland and outside of that I develop graphics drivers' - primary-source confirmation of the Google SRE identity, written before his 2026 move to HRT.
• Co-started the RADV open-source Vulkan driver for AMD hardware with Dave Airlie in 2016 as part of the Mesa project; it grew to about 4 full-time contributors able to run most games via DXVK/VKD3D-Proton - an unusual depth of GPU-driver work maintained alongside a full-time SRE job.
• Competed for the Netherlands at the International Olympiad in Informatics in 2010 (silver medal, rank 52, 655/820) and 2011 (silver medal, rank 59, 401/600) - both confirmed by the IOI statistics profile and CPHOF timeline.Jul 29, 2011
• Competed for the Netherlands at the International Olympiad in Informatics in 2010 and 2011; the IOI statistics site lists both appearances, with a silver medal in each year (rank 52 in 2010, rank 59 in 2011).
• Maintains a personal blog on open-source GPU drivers (RADV/Vulkan) at basnieuwenhuizen.nl, which links his GitHub (github.com/BNieuwenhuizen), Twitter (@b_nieuwen), a Mastodon account (@bas@mastodon.gamedev.place), and a second LinkedIn profile URL (linkedin.com/in/bas-nieuwenhuizen-b336a838).
• His personal site links his GitHub (github.com/BNieuwenhuizen), Twitter (@b_nieuwen), a Mastodon account (@bas@mastodon.gamedev.place) and a legacy LinkedIn URL (linkedin.com/in/bas-nieuwenhuizen-b336a838) - corroborating that all these accounts belong to the same person.
• Started his hobbyist emulator/JIT-compiler work during high school and early university (writing successive tracing JIT compilers for CPU emulation) before moving into graphics drivers when AMD pushed open-source drivers - a self-directed systems/compiler trajectory predating his professional roles.
• LinkedIn public directory snippet (an index/aggregator derived from LinkedIn, not independent primary-source confirmation) displays 'Bas Nieuwenhuizen - Software Engineer at Hudson River Trading, Adliswil', consistent with the enrichment backbone's HRT role.
