What I'm looking for

I’m looking for a role where I can own derivatives and counterparty credit risk analysis, partner with trading desks on capital/clearing constraints, and turn stress-test insights into actionable execution and portfolio decisions.

Right now, I’m a Trading Risk Management Analyst at ING, where I analyze and stress-test counterparty credit exposure across a €72bn EAD portfolio of derivatives and securities lending. I translate risk findings into senior-level credit decisions, and I deliver monthly exposure and capital analysis to senior management and the trading desk.

Before ING, I was a Trader at Mint Tower Capital, managing a €1bn global portfolio across Europe, Asia, and the Americas. I exploited volatility and credit mispricings to deliver a 25% annual return, while conducting fundamental credit and equity research on convertible bond issuers to drive investment decisions in convertible bond arbitrage. I also served as a key market advisor to issuers on convertible-bond placement, advising on pricing, market appetite, and trade execution strategies to maximize deal success.

Earlier, as a Financial Analyst at Slim Cloud, I supported fundraising by preparing financial forecasts and engaging with VCs and investors for equity and debt financing. I helped grow pipeline by identifying and qualifying new business leads from client cloud cost statements—estimating potential savings and generating targeted outreach strategies.
