Buy-side and sell-side fixed income platform analysis — pre-trade data delivery, portfolio management tooling, FIX and GUI interface design, and transaction cost analysis for execution price benchmarking.
Power and Gas trade brokering platforms integrated with Trayport — requirements capture, functional design, counterparty matching workflows and trade lifecycle management for energy commodities.
Business analysis for institutional-grade crypto trading platforms — matching engine design, fee and rebate model re-engineering, funding pools, liquidation logic and smart order routing for spot and margin trading.
End-to-end delivery of centralised middle office platforms — integrating front and back-office systems, automating workflows, ensuring regulatory compliance and boosting operational efficiency.
