Dermot D.

I build the tools trading desks depend on: FIX connectivity, broker API integrations, real-time Excel add-ins, Bloomberg data pipelines and risk management. I’ve spent 13 years on the trading floors of ING Barings Japan and UBS Securities Japan, both as a desk developer and as a sales trader on the electronic trading desk. I understand how traders work, what they need, and how little room for error there is. Since 2012 I’ve worked independently for hedge funds, prop traders, fintech firms and broker-dealers. Typical work: - Broker connectivity and live strategy execution (FIX/QuickFIX, IBKR TWS API, Schwab Trading API, IRESS API) - Real-time Excel/VBA and Excel-DNA add-ins and desk tools - Bloomberg API data pipelines and analytics - Stock and options screeners - Risk, P&L and fund reporting systems (Python, Azure SQL Database, Plotly Dash, Excel/VBA) Stack: C#/.NET, Python, Java, Excel/VBA, SQL Applied Physics degree. Passed CFA Level 1. I specialise in complex trading and financial systems where reliability, precision and a deep understanding of market workflows are essential. I'm particularly interested in challenging, long-term engineering work involving trading infrastructure, data pipelines and financial applications.
