Johan Gunardi

Johan Gunardi is a Singapore-based trader at Jump Trading LLC. He represented Indonesia at the International Mathematical Olympiad in 2010 (bronze) and 2011 (silver) while a student at SMAK PENABUR Jakarta, then studied Mathematics at the National University of Singapore, where he received the Lee Kuan Yew Gold Medal and Medal of Excellence in Mathematics at Commencement 2015. His professional history reported in index data runs Barclays (quantitative analyst intern, 2014), Credit Suisse (FX structurer, 2015-2016), DRW (trading analyst 2016-2021, then a non-compete period 2021-2022), and Jump Trading (trader, 2022-) - the post-2014 roles at market-making and trading firms are the quantitative-finance relevant ones.

• Quant employment verification: UNRESOLVED. Employment evidence: LinkedIn index data reports a continuous trading career (Barclays quant intern 2014, Credit Suisse FX structurer 2015-2016, DRW trading analyst 2016-2021, DRW non-compete 2021-2022, Jump Trading trader 2022-) at firms that genuinely operate in quantitative finance (market-making proprietary trading at DRW/Jump; bank trading desks at Credit Suisse/Barclays). Employer classification: all relevant. However, no primary source (the person's own LinkedIn page, a company team page, press) was independently read, and directory aggregators repeating the same index data do not constitute independent confirmation; the identity bridge from the IMO medalist to the trader is likewise not explicitly documented. Status is therefore UNRESOLVED rather than CONFIRMED.Sep 17, 2026
• Quant employment verification: UNRESOLVED - see dedicated note below.
• Career timeline reported in LinkedIn index data (index-only, not independent primary confirmation): Trader, Jump Trading LLC, Singapore, 2022-present; DRW 'Non-Compete', Singapore, 2021-2022; DRW Trading Analyst, Singapore, 2016-2021; Credit Suisse FX Structurer, Singapore, 2015-2016; Barclays Quantitative Analyst Intern, 2014.
• Identity bridge caveat: no single source read states that the Indonesian IMO medalist Johan Gunardi (2010/2011) is the Singapore-based trader. The link rests on the shared name plus a consistent Indonesia->NUS Mathematics->Singapore finance trajectory; treat the Olympiad achievements and the finance employment as separately sourced.
