Work Experience

Graduate Energy Trader (National Grid Ventures) at National Grid
March 1, 2025 - Present
Achieved trading authorisation rapidly and ramped to top-tier desk performance in a high-pressure, real-time environment. Delivered consistently positive net PnL by deploying a forecast-and-constraints execution framework, converting probabilistic signals into objective, rule-based decisioning with explicit risk limits. Built and maintained production Python analytics for imbalance/regime forecasting, integrated into trader workflow (tools/checklists) to improve entry/exit timing and capacity allocation. Improved model robustness by calibrating thresholds using settlement-period stratification and like-for-like benchmarking; monitored performance drift and adjusted assumptions as market conditions changed. Reduced adverse selection by incorporating FR/BE microstructure drivers into execution logic during volatile / liquidity-thin regimes. Led an internal REMIT tool overhaul end-to-end (delivery, DQ controls, risk/timeline management, director updates), ensuring reliable pre-market prep
Graduate Power System Engineer at National Grid
September 1, 2024 - March 1, 2025
Assessed early-stage options for complex, high-dependency transmission projects and produced investment cases aligned to Net Zero 2050 with structured scenario analysis and rigorous CBA. Advanced cross-functional pilots by defining delivery strategy, governance, schedules and risk controls to move options toward investment-grade decisions; coordinated engineers and external stakeholders to align assumptions and outputs. Partnered with consultants to redesign workflows and tooling, improving delivery efficiency by >3× and establishing repeatable playbooks for future projects.
